Product Description

The HC42X-16Q silent check valve consists primarily of a valve body, valve seat, flow guide, valve disc, bearings, and springs. Its streamlined design ensures minimal pressure loss. It is widely used in water supply and drainage, fire protection, and HVAC systems, and can be installed at the outlet of a pump to prevent backflow and water hammer damage to the pump.

How It Works

The HC42X-16Q silent check valve has a very short disc opening and closing stroke. When the pump is shut down, the valve closes quickly, preventing loud pump noise and providing a silent operation.
