POPU Valve: Stainless Steel Swing Check Valve
Stainless steel swing check valve disc disc shape, around the seat channel of the axis of rotation movement, because the valve channel into a streamlined shape, flow resistance than lifting check valve is smaller, suitable for low flow rate and flow infrequent changes in large diameter occasions, but not suitable for pulsating flow, its sealing performance is not as good as lifting type.
