Buy Resilient Seat Seal Gate Valves which Can be Customized From Our Factory in China
1.Introduction of Resilient Seat Seal Gate Valves
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.

3.Key points of operation of Resilient Seat Seal Gate Valves:
1) The opening and closing direction of Resilient Seat Seal Gate Valves should always be closed clockwise.
2. Pneumatic valves in the Resilient Seat Seal Gate Valves pipe network are often opened and closed manually, and the number of opening and closing revolutions should not be too much, that is, large-diameter valves should also be within 200-600 revolutions.
3) Resilient Seat Seal Gate Valves In order to facilitate the opening and closing operation of one person, the larger opening and closing torque should be 240N-m under the pressure of the pipeline.
4) The opening and closing end of Resilient Seat Seal Gate Valves should be a square tenon, with standardized dimensions, and face the ground so that people can directly operate it from the ground. Valves with roulette are not suitable for underground pipe networks.
