XUVAL lift check valve is applicable for medium steam,water,oil etc.it can prevent fluid from backflow by deadweight of disc and the pressure differences of fluid.
Check valve is also called reverse flow valve, check valve, back pressure valve, check valve.This kind of valve depends on the flow of the medium itself in the pipeline and automatically open and close the force, belongs to a kind of automatic valve.
Flange check valve is to rely on the flow of the medium itself and automatically open, close disc, used to prevent the medium backflow valve, also known as the check valve, one-way valve, reverse flow valve, and back pressure valve.
Stainless steel sandwiched check valve is also known as reverse flow valve, check valve, back pressure valve, one-way valve.This kind of valve depends on the flow of the medium itself in the pipeline and automatically open and close the force, belongs to a kind of automatic valve.
Wafer check valves are mechanical devices whose main function is to prevent backflow of media.
Check valves are automatic valves that open and close depending on medium pressure.
Silent check valve is to rely on the flow of the medium itself and automatically open, close the disc, used to prevent media backflow valve, also known as check valve, one-way valve, silent check valve backflow valve, and back pressure valve.
H71H(W) Check valve consists of valve body, disc, spring, etc. It is installed horizontally or vertically in the pipeline system to prevent media backflow. It has short structure, small volume and light weight.Fast disc closing, low water hammer pressure;The flow passage is unobstructed and the fluid resistance is small;Sensitive action, good sealing performance.
Internal screw swing check valves refer to opening and closing parts by the flow of media and force to open or close, in order to prevent the media backflow of the valve.
High precision, beautiful appearance, small shape, with spring device, vertical and horizontal installation can be.
