Swing check valve depends on the flow of the medium itself and open/closed the disc automatically, usually used to prevent the reserve flow of the medium of the valve, also named to the one-way valve, counter flow valve. And swing check valve can only be installed vertically not horizontally. Suitable for cleaning medium, not for medium containing solid particles and large viscosity.
