DUAL PLATE CHECK VALVE

उत्पाद वर्णन

Dual Plate Check Valve “ Compact, Energy-Efficient Non-Return Valve

The Dual Plate Check Valve is a compact, lightweight, and energy-efficient non-return valve designed to prevent reverse flow in pipelines. Featuring a dual-spring-loaded disc mechanism, it provides fast shut-off, reduced water hammer, and minimal pressure drop. Its wafer-type design fits snugly between flanges, making it ideal for installations with space and weight constraints.

Manufactured using durable materials like Cast Steel, Ductile Iron, SS304, SS316, and Bronze, our valve offers corrosion resistance, long service life, and tight sealing in both vertical and horizontal pipelines. This valve is widely used in water, steam, oil, gas, chemical, and HVAC systems.
