Valsteam ADCA’s PV25 On-Off valves are single seated, two-way body constructed with in-line straight connections. The PA pneumatic actuator features a rubber diaphragm and multi-springs, and its action can be DA-direct action (air to close) or RA-reverse action (air to open). Their wide application range allows these valves to be used with the most common process fluids, including water, superheated water, steam, air, gas and other non-corrosive fluids. Choose from either a single seated, two-way, direct or reverse action valve. The valve’s top flange is permanently attached to the body, meaning removal is unnecessary for replacing the actuator. Soft sealing comes as standard.
