1.Adjustable and Controllable Closing Performance for Proactive Water Hammer : Suppression By adjusting the weight or moment arm of the counterweight, the closing speed and final seating force of the valve disc can be precisely controlled, enabling flexible configuration ranging from "quick closing" to "multi-stage slow closing". It actively decelerates during the final phase of valve closure and smoothly cuts off backflow, thereby effectively absorbing pipeline impact energy and protecting pumps, pipelines and connectors from water hammer damage.
2.Reliable Sealing Ensured Under Low Pressure and Complex Flow Conditions : The counterweight provides a stable supplementary closing force, which does not rely entirely on medium backflow.Even under operating conditions such as extremely low system pressure, upward flow in vertical pipelines, or high-viscosity media, it can still ensure the valve disc closes fully and tightly, preventing medium micro-leakage and enhancing system safety.
3.Enhanced Adaptability to Complex Operating Conditions : The external counterweight mechanism is insensitive to impurities and particles in the medium, and delivers stable closing force.It is highly suitable for media containing solid particles such as sewage, sludge and mineral slurry, and can better adapt to systems with frequent fluctuations in flow rate and pressure, reducing valve disc flutter and wear.
