Dual Plate Check Valve

The Honeywell Dual Plate Non-Return Check Valve (Model: HWNRV) is a reliable and efficient solution for preventing reverse flow in HVAC, water, and fuel systems. Specially designed for chilled and hot water applications, this valve ensures smooth system operation and protects critical equipment from damage caused by backflow.

Built with a cast iron body (IS 210 FG 220 CI) and a lapped ductile iron disc, the valve offers excellent durability, strength, and long service life. The ASTM A276 Grade SS 410 shaft enhances mechanical reliability, while the dual plate design makes it lighter, more compact, and more efficient compared to conventional check valves.

With a nominal pressure rating of PN16 and a working temperature range of -10°C to +110°C, it is suitable for a wide range of industrial and HVAC applications. The flanged end connection ensures secure installation and compatibility with standard piping systems.

Engineered for performance, the valve provides low leakage (0.5 kg/cm²) and is tested for safety with 24 bar shell pressure and 17 bar seal pressure, ensuring dependable operation in demanding conditions.
