Technical Feature

OPERATION:
In its steady state, the valve allows flow from ① to ② . The spring chamber is vented to atmosphere.On attainment of a pre-determined pressure at ② ,the cartridge shifts to restrict input flow at ① ,thereby regulating pressure at ② .

ASSEMBLY INFORMATION:
1. Before screwing in the valve, loosen the lock nut and sealing nut until the travel stop.
2. Screw in the valve and tighten with the specified torque. The metallic sealing of the inlet to the outlet is formed between the facial sealing edge of the valve and the shoulder of the stepped hole in the basic body.
3. Tighten lock nut and sealing nut with specified torque.
