GA44H-16 Double Lever Safety Valve, WCB Cast Steel Flanged Full Lift Lever Weight Safety Valve for Steam Boiler

**GA44H-16 double lever full lift safety valve**, double lever dead weight loading structure. Balances medium pressure by dead weight gravity, free from spring aging and fatigue, stable long-term operation. WCB cast carbon steel body, alloy steel overlay sealing surface with high temperature and wear resistance. Flange connection, full lift design with large discharge capacity. Set pressure can be adjusted on site by moving the weight. PN16 nominal pressure. GB, ASME, DIN, BS, JIS flanges optional. Automatically opens for discharge when system overpressure and re-seats tightly as pressure drops. Widely used for overpressure protection of power boilers, thermal pressure vessels, steam pipelines and air compressor storage tanks.
