Flanged Gate Valve Dimensions Flange ends Gate Valve
The gate valve is a gate of the opening and closing member. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and closed, and the gate valve can only be opened and closed, and the gate valve is not suitable for door parameters, usually 5 °, and the medium temperature is not higher than 2 ° 52 '. The manufacturability of the gate valve is improved. The deviation of the angle of the sealing surface in the machining process is compensated, and the gate is called an elastic ram.
Nominal diameter: 1/2" - 24" (DN15 - DN600)
Pressure range: Class 150 - 900 (PN16 - PN150)
Working temperature: -196℃ - +560℃
Body material: WCB, WCC, LCB, LCC, WC6, WC9, C5, C12, CF8, CF8M, CF3, CF3M, CF8C, CN7M, etc.
Operation: HandWheel, Gear, Electricty, etc.
1.The flow resistance is small. The internal medium channel of the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.
2. It is easier to open and close. Compared with the globe valve, the gate movement direction is perpendicular to the dielectric flow direction, whether it is open or closed.
3.the height is large, the opening and closing time is long. The opening and closing stroke of the gate is large, and the drop is carried out by the screw.
4.The phenomenon of water hammer is not easy to produce. The reason is that it takes a long time to shut down.
5.the medium can flow in any direction on both sides, easy to install. The two sides of the gate valve channel are symmetrical.
6.the length of the structure (the distance between the two connecting ends of the shell) is small.
7.the body is simple, the structure length is short, the manufacturing process is good, and the scope of application is wide. The utility model has the advantages of compact structure, good valve rigidity, smooth passage, small flow resistance, stainless steel and cemented carbide, long service life and ptfe packing. The seal is reliable. The operation is light and flexible.
