Bs5163 Stainless Steel Gate Valve manufacturers tell you that the gate of the gate valve moves linearly with the valve stem, which is called a lift-rod gate valve (also called a rising stem gate valve). Usually, there are trapezoidal threads on the lift rod. Through the nut at the top of the valve and the guide groove on the valve body, the rotary motion is changed into a linear motion, that is, the operating torque is changed into the operating thrust. The manufacturer of Bs5163 Stainless Steel Gate Valve tells you that the sealing surface can be sealed only by the medium pressure, that is, relying on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the valve is closed, the gate must be forced against the valve seat by external force to ensure the tightness of the sealing surface.

Installation and maintenance:
1. The Bs5163 Stainless Steel Gate Valve manufacturer tells you that the handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
2. The double gate gate valve should be installed vertically (that is, the valve stem is in a 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 according to the provisions of the product instruction manual.
5. The Bs5163 Stainless Steel Gate Valve manufacturer tells you that if the valve is used frequently, lubricate it at least once a month.
