130CL Series Spring Bottom Brass Shut Off Valves for Water and Air Systems

A small shut off valve can decide whether a water process line is easy to isolate or a maintenance task becomes slower than it needs to be. In air supply systems, the same part can affect how quickly a branch line, gauge, fixture, or device can be taken in and out of service.

The 130CL Series Spring Bottom Brass Shut Off Valves are built for that kind of practical, repeated use. They are compact brass plug valves designed for instantaneous off-on operation, with a standard 360° rotation and an optional 90° off-on rotation when the application calls for a shorter handle movement.

The series is rated at 30 psig and covers a temperature range of -40° to 250°F. The valve body and plug are made from lapped brass, and each body and plug are individually mated. That matters because the fit between those two parts affects how smoothly the valve turns and how reliably it seals in normal service.

A compact brass shut off valve is often used where quick isolation matters.

What makes the 130 brass shut off valve series useful in process piping

The main appeal of the 130 series is the combination of simple operation, brass construction, and multiple connection styles. These valves are not complex control valves. They are meant to provide fast, direct shut off in systems where a manual on-off function is needed.

The standard operation uses a 360° rotation. In practical terms, that means the valve can be turned fully through its range in a continuous motion. For installations where a more defined quarter-turn motion is preferred, a 90° off-on rotation can be furnished.

That optional 90° rotation can be useful when:

• The valve is installed in a tight panel or pipe rack

• The operator needs a clear open or closed position

• Nearby components limit handle travel

• Repeated operation favors a shorter, quicker motion

  
  

The 30 psig rating makes the valve suitable for low-pressure services such as many water process piping layouts and air supply systems. It is not a high-pressure valve, and it should not be treated as one. Matching the valve to the pressure and temperature of the service is the first step in choosing the correct part.

The broad temperature range, from -40° to 250°F, gives the series room to serve in cool ambient conditions as well as warm service environments. As with any brass valve, the full application should still be checked against the fluid, pressure, temperature, connection method, and installation conditions.

The lapped brass body and plug are the core of the design

Plug valves depend on fit. The plug rotates inside the valve body to open or shut the flow path. If the fit is rough or inconsistent, the valve can feel stiff, wear unevenly, or fail to provide the smooth action expected in service.

The 130 series uses a lapped brass body and plug. Lapping is a finishing process that helps create a close, smooth mating surface. In this series, the body and plug are individually mated. That means the two working parts are matched as a set rather than treated as fully interchangeable generic pieces.

This construction supports three practical benefits.

Lower operating friction

A smoother fit helps the valve turn with less effort. That is especially useful when valves are used often, or when they are installed in locations where awkward reach makes stiff operation frustrating.

Consistent shut off performance

The quality of the contact between plug and body plays a direct role in shut off. A well-mated plug and body help the valve do its basic job with less fuss.

Simple mechanical reliability

Brass plug valves are valued because they are direct and easy to understand. There is no complicated actuation system in the basic valve. The operator turns the valve, and the flow path opens or closes.

That simplicity is one reason these valves are used extensively in water process piping and air supply systems. The application may be ordinary, but the valve still needs to feel right and function consistently.

Common services include water process lines and air supply systems

The product brief points to two common uses: water process piping and air supply systems. Both services benefit from a compact valve that can be opened or shut quickly.

In water process piping, a valve in this class may be used to isolate small lines, sample points, instrument feeds, or utility branches. These are places where a full-size industrial valve may be unnecessary, but dependable shut off still matters.

In air supply systems, the valve may be used on smaller branch lines or at points where equipment needs to be isolated. Air systems often include many small connection points, and a compact brass shut off valve can make service work easier.

Typical selection questions include:

• What is the system pressure?

• What is the normal and maximum temperature?

• Is the service water, air, or another compatible fluid?

• Does the line use pipe thread, tube connection, or a combination?

• Is a straight-through, male, female, or tube-to-pipe configuration needed?

• Is 360° operation acceptable, or is 90° operation preferred?

  
  

The 130 series has also been produced in many special versions for other services. That does not mean every service is automatically suitable. It means the base design has been adapted before, and applications not shown in the standard listing may still be possible with the right review.

The available 130 series connection styles

The 130 series includes several catalog groups, each aimed at a different connection need. The part numbering uses suffixes such as J, L, N, and P to indicate size combinations. The available sizes include pipe thread connections, tube connections, and tube-to-pipe combinations.

The tables below organize the listed parts into a cleaner reference format. Always confirm the exact connection type, thread details, and service conditions before ordering or installing.

130 female by male pipe thread valves

The 130 group combines female and male pipe thread connections in matching nominal sizes.

Part number	Female by male pipe thread
130C-J	1/8 x 1/8
130C-L	1/4 x 1/4
130C-N	3/8 x 3/8

This style can be useful where one side of the valve needs to receive a male threaded component while the other side threads into a female connection. It can reduce the number of extra adapters in a compact assembly.

131 male pipe thread valves

The 131 group is listed with male pipe thread sizes.

Part number	Male pipe thread
131C-J	1/8
131C-L	1/4
131C-N	3/8

This style suits installations where the valve threads directly into a female port, manifold, fitting, or other receiving connection.

132 female pipe thread valves

The 132 group is listed with female pipe thread sizes.

Part number	Female pipe thread
132C-J	1/8
132C-L	1/4
132C-N	3/8

This style is often the natural choice when both connecting components have male threaded ends or when the valve needs to sit between threaded nipples.

133 tube by pipe thread valves

The 133 group connects outside-diameter tube to pipe thread. These valves are listed as complete with nut and sleeve.

Part number	O.D. tube by pipe thread
133C-4J	1/4 x 1/8
133C-4L	1/4 x 1/4
133C-5J	5/16 x 1/8
133C-5L	5/16 x 1/4
133C-6L	3/8 x 1/4

This group is helpful when a tube line must connect to a threaded port. The supplied nut and sleeve simplify matching the valve to the tube connection.

134 O.D. tube valves

The 134 group is listed by outside-diameter tube size and is complete with nuts and sleeves.

Part number	O.D. tube
134C-4	1/4
134C-5	5/16
134C-6	3/8
134C-8	1/2

This is the more direct choice for tube-to-tube shut off service where both sides of the installation use compatible tube connections.

135 O.D. tube valves

The 135 group is also listed by tube size, with suffixes that indicate related size variants.

Part number	O.D. tube
135C-4J	1/4
135C-4L	1/4
135C-5J	5/16
135C-5L	5/16
135C-6L	3/8
135C-8N	1/2

Because this group includes similar tube sizes with different suffixes, the suffix should be checked carefully against the required end configuration before selection.

136 O.D. tube valves

The 136 group includes common tube sizes.

Part number	O.D. tube
136C-4	1/4
136C-5	5/16
136C-6	3/8
136C-8	1/2

Like the other tube styles, these parts should be matched to the outside diameter of the tube, not just the approximate line size.

How to choose the right valve from the series

Choosing from the 130 series is mostly a matter of narrowing the service, size, and connection style.

Start with the operating conditions. The series rating is 30 psig, and the temperature range is -40° to 250°F. If the system runs outside those limits, the application needs a different valve or a special review.

Next, identify the connection type. Pipe thread and tube connections are not interchangeable, and tube sizing should be based on outside diameter. A 3/8 tube connection is not the same thing as a 3/8 pipe thread connection.

Then decide how the valve will be operated. The standard 360° rotation works well in many simple installations. If the operator needs a quarter-turn feel, or if space limits movement, the 90° off-on version may be a better fit.

Finally, look at assembly convenience. A valve complete with nuts and sleeves can save time when the connection is tube-based. In tight layouts, the right end configuration can also remove the need for extra fittings.

A clear selection process looks like this:

1. Confirm pressure and temperature.

2. Confirm service compatibility.

3. Choose pipe thread, tube, or tube-to-pipe configuration.

4. Match the exact size and suffix.

5. Decide between standard 360° operation and optional 90° operation.

6. Review any special requirements before purchase.

   
   

Special versions may solve unusual requirements

The standard catalog listing covers many common needs, but it does not cover every possible installation. The product brief notes that many special versions of these valves have been produced for other services.

That matters for older equipment, custom utility skids, replacement work, and compact process systems where a standard connection may not fit cleanly. If the required application is not shown, the practical next step is to compare the service conditions and connection needs against the available valve types.

A special or adapted version may be realistic when:

• The pressure and temperature remain within a suitable range

• The service is compatible with brass construction

• The required connection is close to an existing catalog type

• A minor change can avoid a costly piping redesign

• A low-friction manual shut off valve is still the right basic design

  
  

Not every request will make sense, but the 130 series has enough variation to make adaptation possible in some cases.

A practical valve for small-line shut off service

The 130 Series Spring Bottom Brass Shut Off Valves fit a clear role. They provide fast manual shut off for low-pressure water and air systems, with enough connection options to suit many small piping and tubing layouts.

Their value comes from the basics done well: lapped brass construction, individually mated body and plug, low-friction operation, and a useful range of pipe and tube sizes. For systems rated within 30 psig and -40° to 250°F, they offer a compact way to add dependable off-on control.

The best choice is the one that matches the service conditions and the physical connection without extra guesswork. Confirm the pressure, temperature, fluid, size, and rotation style before selecting a part number. When the standard table does not show the needed arrangement, a special version may still provide an economical path without changing the whole system.
