Stack-mounting Pilot-operated Check Valves SREDescriptionISO sizes 2 … 7, series SRE… / SREA… / SREZ… Pilot-operated check valves prevent any flow in one direction. In the opposite direction, free flow with minimal pressure drop is possible. By applying a defined pilot pressure at X, the checked flow direction is held open as long as the pilot pressure is maintained.Stack-mounting valves with ISO / DIN / NFPA / ANSI interface. Advantages
