The opening and closing part of the hard sealed gate valve is the gate plate, whose motion direction is perpendicular to the fluid direction. The gate valve can only be fully opened and closed without adjustment or throttling.
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 seali1
FEP(F46),PTFE(F4) Fluorine-lined butterfly valves are applicable for -50℃~150℃ nitrohydrochloric acid,sulfuric acid,hydrochloric acid,hydrifluoric acid of vanous concentrations and vanous organic acid, strongacid and strong oxidant.
Fluorine lined diaphragm valve is a special form of cut-off valve, appeared in the 1920s.Its opening and closing parts is a diaphragm made of soft material, the valve body cavity and valve cover cavity and drive parts separated, so called diaphragm valve.
