Product Detail

The LCB Pressure Seal Gear Operated Gate Valve is a high-integrity solution specifically engineered for high-pressure Nutrient Deaerated Water systems. Constructed from ASTM A352 LCB, it provides exceptional impact toughness and structural stability in varying environmental temperatures. The Pressure Seal design utilizes internal fluid pressure to tighten the bonnet seal, making it superior to traditional bolted bonnets for high-pressure isolation. Equipped with a high-ratio gear operator, this valve ensures smooth and reliable manual operation for boiler feed water and thermal power applications.

Design Description

Pressure-Responsive Sealing: The self-reinforcing pressure seal mechanism ensures that the higher the line pressure, the tighter the bonnet seal, eliminating the risk of gasket blowout in high-pressure deaerated water lines.
LCB Low-Temp Resilience: The A352 LCB material is ideal for facilities in colder regions or systems subject to thermal cycling, preventing brittle fracture where standard WCB might fail.
Optimized for Deaerated Water: Features Stellite-faced (Trim 5) seating surfaces to resist the "wire-drawing" effect and erosion typical of high-velocity deaerated water flows.
Mechanical Advantage (Gear Operator): The precision-engineered worm gearbox allows for effortless manual shut-off against high differential pressures, providing self-locking safety.
Full Port Flow: Minimizes pressure drop across the valve, ensuring efficient water supply to boilers and deaerators.
