Double-disc Swing Check Valve

Compact and lightweight: clamp-type connection, the structural length is shortened by 30%-50%, suitable for space-constrained scenarios.

Rapid valve closing: spring-assisted + short-stroke design, closing time ≤0.3 seconds, effectively suppressing water hammer (pressure peak drop of 70%) and impact noise (<65dB).

Intelligent sealing: spring pre-tightening maintains the normally closed state, and double seals (metal + elastomer) ensure zero leakage.

Wide-area adaptation: suitable for water supply and drainage/high-rise buildings/industrial systems, supporting solid-containing media (particles ≤15mm) and -20℃~180℃ working conditions.

Convenient maintenance: modular design, support online replacement of seals, maintenance time <1 hour.

The Double-disc swing check valve is mainly composed of important parts such as valve body, valve disc, valve shaft and spring. It adopts a lightweight design in the form of clamp connection. Due to the shortened closing stroke of the valve disc and the accelerated closing effect of the spring elastic force, water hammer and water impact sound can be reduced when the medium flows back. The valve disc is in a normally closed state under the action of the spring. This valve is mainly suitable for water supply and drainage systems, high-rise buildings and industrial areas. Since the structural length is shorter than that of ordinary check valves, it is most convenient for places with limited installation space.
