Diaphragm valve PS46

pilot-operatedpressure sustainingfor steam

The ADCA PS46 series pressure sustaining valves are single seated, diaphragm or piston sensing bellows sealed controllers, that operate without auxiliary energy. These valves are designed for use with steam, compressed air, and other gases compatible with the construction. These valves are particularly suitable for sustaining steam pressure in all energy and process systems where minimum upstream pressures must be kept under control. Specially designed high durability bellows, providing pressure balancing and frictionless plug stem. Robust construction (fit-and-forget). Interchangeable actuators and adjustment springs. Soft sealing in PTFE/GR for use with steam. Soft sealing in nitrile rubber for use with air and gases. Low-noise flow divider. Sensing pipe on body. Steam, compressed air and other gases compatible with the construction. Limited use with liquids. Consult manufacturer before installing the valve with liquids.
