The opening and closing parts of the Gate Valve are gates. The direction of movement of the gate is perpendicular to the direction of the flow. The gate valve can only be fully opened and fully closed and cannot be adjusted or throttled. The gate plate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form a wedge shape, and the wedge angle varies depending on the valve parameters, usually 5°, and 2° 52′ when the medium temperature is not high. Gate valve has the following characteristics:
1. The sealing performance is good, the fluid resistance is small, and there is a certain regulation performance;
2. But the size is large, the structure is complex, the processing is difficult, the sealing surface is easy to wear, it is difficult to maintain, and the opening and closing time is long. Suitable for making large-diameter valves, in addition to steam, oil and other media, but also suitable for medium containing granular solids and high viscosity, and suitable for valves for venting and low vacuum systems.
We also have Globe Valve and Check Valve, which can be supplied in large quantities.
