Product description
The gate of the fire-fighting grooved open-stem gate valve moves linearly with the valve stem. Usually there is a trapezoidal thread on the lifting rod. Through the nut on the top of the valve and the guide groove on the broad body, the rotation The operating torque becomes the operating thrust. By turning the hand wheel, the valve plate linked with the valve stem is raised or lowered through the advance and retreat of the thread of the hand wheel and the valve stem to achieve the purpose of opening and closing. The opening and closing part of the open-stem gate valve is a gate, and the moving 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.
