Resilient Seat Seal Gate Valves are also called lifting stem gate valves, also called rising stem gate valves. Usually there is a trapezoidal thread on the lifting rod, through the nut on the top of the valve and the guide groove on the valve body, the rotary motion is changed into linear motion, that is, the operating torque is changed into operating thrust. The opening and closing part of Resilient Seat Seal Gate Valves is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. It can only be fully opened and closed, but cannot be adjusted or throttled. The Resilient Seat Seal Gate Valves produced by Milestone Valve Company have stable performance and are used in various fields such as petroleum, chemical industry, and water conservancy.
