TEMCo Industrial pneumatic air control valves feature a variety of manual actuators that allow the user to quickly change between a set of directions of flow, also known as "positions," in order to control the flow of pressurized air through desired ports. Thus, any single direction of flow, or "way," can be altered with a simple flick of a switch, press of a button, twist of a knob, or turn of a lever, as well as other manual options.

Application of these control valves are suitable for any pneumatic task, from DIY projects at home to burly industrial use. With varying port sizes from 1/8", 1/4", 3/8", and 1/2" NPT, diverse valve body sizes and forms, as well as pre-drilled mounting holes through the body of the controller, you're bound to find the right TEMCo pneumatic controller for your needs.

The most important feature to look for is the actuating type - the way in which you manually control the valve. Whether the controller you're currently looking at on this listing is or isn't the right one for you, take a moment to check out the other pneumatic control valves in our line and see if any of those and their features are better suited for your particular application.

Features

  • A manual push and pull button allows the user to change the direction of flow.
  • Intuitive design ensures simple interface for even the most complex applications.
  • Accurate spool cylinder ensures push or pull button interface achieves flow through the desired ports.
  • Can be panel mounted with the button's shaft or through three pre-drilled mounting holes in the valve's body.
  • Maximum operating pressure of 116 PSI.

Positions, Ports, and Ways

A "port" is the hole in the body of the control valve where a connector and attached hoses may be screwed in. Our port sizes are measured in NPT, ensuring you get the right fit for your application.

In regards to pneumatic control valves, a "way" is the direction in which air can enter or exit a control valve. This, however, can get confusing - not everyone uses the same exact definition of a way, which can lead to inaccuracies. If directions of flow are important to you, and you require more information about how our valves are going to work, check out our section on how to read pneumatic symbols.

A "position" is a set of ways through ports that are achieved by some manual control. For example, our push and pull button pneumatic control valves have two positions: the first position is when the button is pushed in, thus achieving a specified set of flow, and the second position when the button is pulled, achieving a different specified set of flow.

While looking for control valves, we highly recommend you consider how many ports and positions you will need for your particular application.


How to Read Pneumatic Symbols

There are many thorough explanations of these symbols online, but we want to provide with a quick crash course - just enough information for you to make the right purchase.

Pneumatic Control Valve Diagram

Take a look at the symbol above. How many boxes does it have? Two? Three? Each box represents one "position" a valve can have.

In one box, or position, you will see a set of arrows. The set of arrows indicate how air will flow when the pressure port, usually at the bottom middle of any given box, is pressurized. Why are some arrows pointing backwards, then? Because these valves are spool valves, excess air returns through the valve and exist through an exhaust port.

One neat fact is that you don't have to use the designated pressure port as your source of air. You can use any port as a pressure port, and just ignore the pointed ends of the arrows. Instead, imagine the lines as two-way channels, allowing the flow of air in either direction.

Take a look at the outside of the box. Levers, buttons, knobs, solenoids, etc. all have their own actuator symbols. Each actuator symbol's placement is representative of the device, which means that looking at the picture is exactly like looking at the device, as if it were in front of you.

Knowing that the valve and its symbol are oriented exactly, check out the photos of our product and imagine it in front of you, and that you're using it. The position you are in is intuitive: if your lever on the right-hand side of the valve is toggled left, you're in the leftmost position on the schematic symbol. If your push and pull button is on the left hand side of the valve and pushed in, you're in the rightmost position on the schematic symbol.

That's it! We know that this could get trickier, and we're happy to help answer any questions you have before you pick up one of these pneumatic control valves. Give us a call, and a real-live human being here in our California office will pick up and assist you.
