Multiport Relief Valves

multiport-relief-valve

Multiport Relief Valve Springs cannot be compressed solid nor can the valve be locked closed by external adjustment. When springs are compressed to a maximum point by handwheel adjustment, the valve discs will open upon overpressure. Operating components are internal to the valve, which precludes tampering.

Request Information

Designed for maximum safety. The valve and springs are designed for the maximum initial relief pressure indicated on the nameplate. This pressure cannot be exceeded by external adjustment even though the valve is fully adjustable to all pressures within the zero to maximum pressure.
