The basic principle of American standard gate Industrial Valves has the following two programs: a. American standard gate valve opening procedure: 1 until to the fully open position, the valve stem to limit position, sphere rotation to the full open position. 2 in the closed position, the valve body by the Industrial Valves stem [ wiki] Mechanical [ / wiki] Pressure effect, press on the seat. 3 when turn the handwheel counterclockwise, the valve stem is reverse movement, the Angle at the bottom of the plane to make the ball off the seat. 4 stem continue to ascend, and valve stem guide pin of interaction in the spiral groove, the sphere began to rotate without some friction. 2. American standard gate valve closing procedure: 1 last laps of hand wheel rotation, the valve stem mechanically wedge Angle at the bottom of the plane to the oppression of a sphere, make its strong pressure on the seat, to completely seal. 2 is closed, the handwheel clockwise, stem began to drop and the ball left seat begin to spin. 3 continue to rotate the handwheel, the valve stem is embedded in the spiral groove on the role of the guide pin, make the stem and disc rotate 90 ° at the same time. 4 is close to closing the gate body has been in the case of contact with the seat without rotated 90 °.
os&y gate valve are required in the manufacture of almost every product and resilient valve water gate valve is one of the most common machines.
