Swing Disc- Vent Valve


UCC 2 ½” vent valves were designed for on/off service in vessel venting applications on pneumatic conveying systems. The design is rugged, maneuverable, clean operating and easy to maintain. This valve has a replaceable tungsten carbide disc and seat which improves wear resistance and reduces the operating costs. The access covers allow the valve to be adjusted and maintained without removing it from the vent line. UCC 2 ½” vent valve can be shipped pre-piped and fully assembled with an air cylinder and a variety of limit switches and solenoid valves which reduces field assembly and installation costs.
