Product Introduction
Brass swing check valve disc is cylindrical disk-shape, around the seat channel axis to do rotational movement, due to inner channel is the streamline, the flow resistance is smaller than the lift check valve, apply to the low flow rate and seldom flow changes large-caliber occasions, but it should not be used for pulsatile flow, its sealing performance is less than lift type. Swing Check Valve is divided into single disc, double disc, multi disc. These three types are mainly according to valve diameter, for the purpose to prevent the media stopping flow or reflux, reducing the hydraulic compact.
