What is the price of the gate valve?
Different brands and models will have different prices, and the price of gate valves is generally around 2000-3000 yuan. The movement direction of the gate is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the gate. Generally, the sealing surface will be covered with metal materials to increase the wear resistance, such as 1Cr 13, STL6, stainless steel, etc.
When the gate valve is closed, the sealing surface can only be sealed by medium pressure, that is, the sealing surface of the gate is pressed on the valve seat on the other side by medium pressure to ensure the sealing surface, which is self-sealing.
Most gate valves are forced to seal, that is, when the valve is closed, the gate is forced to press against the valve seat by external force to ensure the tightness of the sealing surface.

Matters needing attention
1, handwheel, handle and transmission mechanism are not allowed to be lifted, and collision is strictly prohibited.
2. Double-gate gate valves should be installed vertically (i.e. the valve stem is in the vertical position and the handwheel is at the top).
3. The gate valve with bypass valve should open the bypass valve before opening (to balance the pressure difference between the inlet and outlet and reduce the opening force).
4. The gate valve with transmission mechanism shall be installed as specified in the product manual.
