You don’t even know about gate valves
Introduction of gate valve
The opening and closing part of the gate valve is the 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.
Gate valve construction
It is generally composed of valve body, valve seat, valve stem, gate plate, valve cover, and sealing ring. It can be transformed into a variety of electric gate valves and pneumatic gate valves by equipping the transmission device and gate valve.
The difference between rising stem gate valve and dark stem gate valve：
The open stem gate valve is different from the dark stem gate valve in terms of transmission mode. The open stem gate valve is driven by the handwheel to rotate the nut in situ, and the valve stem rises and falls in a straight line to complete the switch; for the dark stem gate valve, the handwheel drives the valve stem to rotate. The thread (equivalent to a nut) moves up and down to complete the switch.
