Resilient Seated Flanged Gate Valves Cast iron gate valve

Advantages of valves

1. Small flow resistance.The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.
2. Less effort when opening and closing.Compared with the globe valve, because whether it is open or closed, the direction of movement of the gate is perpendicular to the direction of flow of the medium.
3, high height, long opening and closing time.The opening and closing stroke of the gate is large, and the lowering is carried out through the screw.
4, water hammer phenomenon is not easy to produce.The reason is the long shutdown time.
5, the medium can flow in any direction to both sides, easy to install.Gate valve channels are symmetrical on both sides.
6, the length of the structure (the distance between the two connecting ends of the shell) is small.
7, the shape is simple, the structure length is short, the manufacturing technology is good, the application scope is wide.
8, Compact structure, good valve rigidity, smooth channel, small flow resistance, sealing surface made of stainless steel and hard alloy, long service life, PTFE packing.Reliable seal.The operation is light and flexible.

Precautions for installation of Gate valves
1. The installation position, height and inlet and outlet direction must meet the design requirements, and the connection should be firm and tight.
2. Handle of all kinds of manual valves installed on the insulation pipeline shall not be downward.
3. Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
4. Gate valves with driving mechanism should be installed according to the instructions of the product.
