Product description

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

Features

1. The internal flow channel of the silent check valve adopts a streamlined design, which has low flow resistance and energy saving. It is closed by its own spring force to prevent water hammer.

2. When the pump is stopped, the valve flap has a short closing time in multiple springs, which can close quickly, avoid water hammer and prevent huge water hammer sound, forming a silent effect.

3. The valve needs to be installed vertically (the axis of the valve body is vertical).
