You can rest assured to buy customized Metal seated gate valve for corrosive fluids from Milestone. We look forward to cooperating with you, if you want to know more, you can consult us now, we will reply to you in time!The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge.
The opening and closing part of Metal seated gate valve for corrosive fluids is a gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces.
The two sealing surfaces of the most commonly used model gate valve form a wedge. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce slight deformation. In order to improve its manufacturability and compensate for the deviation of the angle of the sealing surface during processing, this kind of gate is called an elastic gate.
