Swing type flange check valve can only be installed vertically, can not be installed horizontally, swing check valve by the medium to the valve disc rotation direction flow to open, otherwise closed. Suitable for clean medium, not for medium containing solid particles and large viscosity.
Rubber seat Swing check valve can prevent liquid countercurrent phenomenon, protect pump equipment .due to the cantilever check valve, the fluid resistance is small; all plastic material manufacturing, play acid and alkali corrosive fluid strong corrosion resistance; Not only can the valve body be removed from the piping, but also the valve cap can be opened for internal inspection and maintenance.
metal seat swing check valve with rocker arm swing structure, all valve opening and closing parts are installed in the valve body, do not penetrate the valve body, in addition to the flange part with sealing gasket or sealing ring seal, the overall no leakage point, put an end to the possibility of leakage of the valve.
Carbon steel swing check valve refers to the opening and closing parts of the circular disc and by its own weight and media pressure generated action to block the media flow back valve.Automatic valve class, also known as check valve, one-way valve, backflow valve or isolation valve.Disc motion is divided into lifting and swing.Lift check valves are similar in construction to globe valves except for the stem that drives the disc. carbon steel swing check valve
