Metal Seat Gate Valve Characteristic:Medium: Water, Waste Water, Air, OilTemperature: -20 to 425ºC

The opening and closing part of the metal seat gate valve is a 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.According to the sealing surface configuration, it can be divided into wedge gate valve and parallel gate valve. Wedge gate valve can be divided into: single gate, double gate and elastic gate; parallel gate valve can be divided into single gate Plate type and double gate type. Divided according to the thread position of the valve stem, it can be divided into two types: open stem gate valve and dark stem gate valve.

Application:

1. The resilient seat gate valve is suitable for non-corrosive gas and liquid medium at room temperature (≤80ºC). Such as clean water, air, oil, water treatment sewage and other pipelines. And has a very good sealing effect, almost zero leakage can be achieved.

2. The Metal seat gate valve is suitable for high temperature (≤425ºC) with slightly corrosive gas and liquid. Such as steam, heat transfer oil, sewage, petroleum, chemical industry, metallurgy, pipelines. Can have a certain degree of wear resistance.

3. The difference between resilient seat gate valve and metal seat gate valve is that the sealing performance of resilient seat is better than metal seat, but the temperature resistance and wear resistance of metal seat gate valve are better than resilient seat gate valve.
