Stainless Steel API Standard Rising Stem 150LB Pressure Flanged Gate Valve

Introduction

The opening and closing part of the gate valve is the gate. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, not adjusted and throttled. The ram has two sealing surfaces. The most commonly used mode is that the two sealing surfaces of the ram valve form a wedge. The wedge angle varies with the valve parameters, usually 50. When the medium temperature is not high, it is 2 ° 52 '. The gate of wedge gate valve can be made into a whole, which is called rigid gate valve; It can also be made into a ram that can produce slight deformation to improve its manufacturability and make up for the deviation of the angle of the sealing surface in the processing process. This kind of ram is called elastic ram. Stainless steel gate valves are divided into 304 stainless steel gate valves, 316 stainless steel gate valves and 321 stainless steel gate valves. The expression method is Z41W-150LBP
