SERIES 2000 Pilot-Operated Backpressure Sustaining Valves
Uses the economical Series 2000 "balanced piston" main valve.
Manufactured 1½ to 8-inch sizes (37 to 200 mm) in globe or angle body.
Threaded (1½ to 3-inch) or ANSI, BS, DIN or ISO flanges (2 to 8-inch).
Available in several variations to accommodate most common pressure control schemes.
Function and Applications
Sustains upstream (inlet) pressure to pre-set minimum regardless of variations in demand, closing tight if upstream pressure drops below minimum. Municipal and industrial uses include sustaining minimum pressure in a zone under periods of high demand, maintaining a minimum pressure against a pump or process (e.g., a pressure filter) and as a pressure relief valve.
