294A High Flow Side Port Air Control Valve
Kingston Model 294A-2 Air Control Valve is a “two step” valve designed for operating single acting cylinders such as those found on lifting devices. It features durable brass construction with Buna-N seals. Inlet stem is designed to provide restricted flow on initial opening with full flow achieved when fully open. Model 294A-2 is designed for a higher flow capacity, providing quicker cylinder operation. Standard valve includes a tank valve. Maximum operating pressure, 150 psi. A “two step” valve is operates when compressed air is directed through the inlet side, or “first step” of the valve to the cylinder port, the cylinder is extended. As long as the lever remains in the neutral position, the air pressure in the cylinder holds the piston extended. When the exhaust port, or “second step” is opened, the air pressure is exhausted to atmosphere, allowing the load on the cylinder to return the piston to its “rest” position.
