F.C. Kingston Inc. Model 298

Kingston Low Flow Side Port Air Control Valve Kingston Model 298-2-6 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 298-2-6 has a vertical bottom cylinder port and come without a tank valve e. 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. The design of the Kingston Model 298-2-6 Air Control Valve differs from the 296-2 only in the tank valve. The tank valve is only present on the 296-2
