Flange End Silent Check Valve
The silent check valve is a high-performance check valve specially designed to eliminate the Water Hammer effect and loud noise caused by the sudden backflow of the interrupted medium in the pipeline system. It represents an important technological upgrade of traditional swing and lift check valves.

Details Description
In a pumping system, when the water pump suddenly stops and the flow rate of the medium drops sharply, the traditional check valve disc (such as swing type) will instantly and abruptly close under the impact of the backflow medium and its own gravity. This sudden diversion will generate huge pressure waves that collide back and forth in the pipeline, which is the water hammer effect. The core mission of the silent check valve is to completely eliminate this destructive phenomenon.
Features
• Eliminating water hammer and noise: Core advantage, protecting the system, creating a quiet environment.
• Lightweight installation: Due to its performance not being affected by the installation Angle, it can be installed horizontally, vertically or at an Angle, greatly increasing installation flexibility (which is incomparable to traditional check valves).
• Low flow resistance: Spring-assisted opening, unobstructed flow path design, and minimal impact on system head loss.
Outstanding anti-backflow performance: The spring preload ensures rapid response and tight sealing with zero leakage.
• Low maintenance cost: It reduces the impact of water hammer on the system and extends the service life of pipelines, pumps and valves themselves.
