Product Description
Product introduction
The silent check valve is composed of a valve body, a valve seat, a fluid guide, a valve flap, a bearing bush and a spring. The internal flow channel adopts a streamlined design, the pressure loss is very small, the valve opening and closing stroke is very short, the pump opening and closing stroke is very short, and the pump can be quickly closed when the pump is stopped, preventing the huge water hammer sound and forming a silent effect. It is mainly used for water supply, drainage, fire protection and HVAC systems. It can be installed at the outlet of the pump to prevent backflow of the medium and damage to the pump by the water hammer.
