Or you just changed your mind. 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. "Manual Override" On Solenoid Pneumatic Control Valves. Even when the solenoid is powered off, so long as the minimum air pressure is met, manually pushing the override button down on the solenoid valve will actuate the pilot valve as if the solenoid were powered on, thus changing the direction of flow to the powered on position.This feature allows you to test the control valve without powering the solenoid on, ensuring whatever pneumatic device you are controlling is operating at your desired specifications. The button may be twist-locked into place, thus keeping the solenoid positioned in the powered on direction of flow. This feature is critical if the direction of flow must remain in the powered on position even in the event of power failure or accidental disconnection of the solenoid to its power source. 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. Take a look at the symbol above. How many boxes does it have?
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? 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. When the solenoid is powered off, air will flow through the normally open position. When the solenoid is powered on, flow will redirect to a secondary set of flow. Can be mounted through pre-drilled mounting holes that run through the valve body.
Integrated manual override and manual test button with twist-to-lock feature. In order to change positions and the direction of flow, our pilot-assisted solenoid control valves require a minimum of 21.76 PSI.
Maximum operating pressure of 116 PSI. Furthermore, we will not mark merchandise values below value or mark items as "Gifts".
