HC42X/DRVZ silent check valve
Product Overview


A silent check valve, also known as a quiet check valve or quiet closure check valve, is a type of valve that helps reduce noise during operation. It is designed to prevent backflow of fluids, such as water or air, in a pipeline. The valve allows forward flow to pass through freely, but closes immediately when reverse flow occurs. This prevents any potential damage to the system due to backflow.

The main advantage of a silent check valve is its noise reduction capability. Traditional check valves can produce a loud banging or slamming sound when they close, which can be disruptive in certain environments or applications.


Product description:

HC42X/DRVZ silent check valve is mainly composed of valve body, valve seat, guide body, valve disc, bearing

It is composed of main parts such as spring and spring, and the internal flow channel adopts a streamlined design with minimal pressure loss. The opening and closing stroke of the valve disc is very short, and it can be closed quickly when the pump is stopped, preventing huge water hammer sound, and has the characteristics of silent closing. The valve is mainly used in water supply and drainage, fire protection and HVAC systems, and can be installed at the outlet of the water pump to prevent backflow and water hammer from damaging the pump.
