API Gate Valve

Product details

1. There are two sealing surfaces of the gate. The sealing surfaces form wedges, and the Angle of wedges varies with valve parameters, usually 5°.
2, the stainless steel gate valve sealing principle is by the wedge on the two sealing surface and the valve body when the two sealing surface wedges, so as to achieve the sealing performance.
3, stainless steel gate valves can be divided into rising stem gate valves (lifting stem gate valves) and dark stem gate valves (rotating stem gate valves) according to the different opening and closing modes of the gate plate driven by the valve stem.
4, stainless steel gate valves can be divided into flexible gate valves and rigid gate valves according to the different structure of the gate.
5. The valve body is cast and bolted to the valve cover, and the middle flange is sealed with wound gasket. If the customer has special requirements, it can be connected with metal ring.
6. Smooth channel and small flow coefficient.Sealing surface by medium erosion and erosion is small.
7. The sealing surface adopts alloy steel or hard alloy, with good abrasion resistance and abrasion resistance.
8, the use of flexible graphite packing, reliable sealing, light and flexible operation.
9, the flow direction of the medium is not restricted, do not disturb the flow, do not reduce pressure.
