A batch of NSV WCB Counterweight Check Valves has been shipped.

Constructed from high-grade WCB carbon steel, these heavy-duty valves are specifically engineered to provide positive backflow prevention in high-pressure industrial pipelines.

Unlike standard swing check valves, this design features an external lever and adjustable counterweight mechanism. The precise counterweight ensures the valve remains fully open at low forward flow and forces a rapid, positive closure the moment flow stops or reverses. This effectively eliminates water hammer, offering maximum protection for pumps and piping systems.

At NSV, we maintain rigorous quality control throughout the entire manufacturing process. Every unit undergoes strict pressure and sealing tests prior to dispatch, ensuring long-term reliability under demanding operating conditions.
