The opening and closing member of the gate valve is a gate. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled. The gate has two sealing faces. The two sealing faces of the most common mode gate valves form a wedge shape. The wedge angle varies with the valve parameters, usually 5°, and the medium temperature is 2°52' when the temperature is not high. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its processability and compensate for the deviation of the sealing surface angle during the machining process.
1. It is more labor-saving when opening and closing. Compared with the shut-off valve, the direction of movement of the ram is perpendicular to the direction of flow of the medium, whether it is open or closed.
2. The water hammer phenomenon is not easy to produce. The reason is that the shutdown time is long.
3. Compact structure, good rigidity of the valve, smooth passage, small flow resistance, stainless steel and hard alloy on the sealing surface, long service life, PTFE packing, reliable sealing, light and flexible operation.

4. Can LongZhu foundry supply machining service as well after casting?
Even if investment casting can reach excellent tolerances, but sometimes, for tighter dimensional tolerances, additional machining will be needed. So to supply finished products, we also have a mature machining production line.
5. What is the lead time of sand castings custom?
Normally, it will take us about 20-30 working days for 1 off sample, and another 25-35 working days for batch production.
