CRAGate Valve Casting

CRAGate Valve Casting

Most of the gate valves are forced to seal, that is, when the valve is closed, the external force is forced to press the gate to the valve seat to ensure the sealing of the sealing surface.

Most of the gate valves are forced to seal, that is, when the valve is closed, the external force is forced to press the gate to the valve seat to ensure the sealing of the sealing surface. The gate of the gate valve moves linearly with the valve stem, called the lift gate valve, also called the open gate valve. Usually there is a trapezoidal thread on the lifting rod, and the rotary motion is changed into a linear motion by the nut at the top end of the valve and the guide groove on the valve body, that is, the operating torque is changed to the operating thrust. When the valve is opened, when the lifting height of the shutter is equal to 1:1 times the diameter of the valve, the passage of the fluid is completely unblocked, but this position cannot be monitored during operation.


Advantage

1. The flow resistance is small. The inner medium passage of the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.

2. The length of the structure (the distance between the two connecting end faces of the casing) is small.

3. Simple shape, short structure length, good manufacturing process and wide application range.

4. 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.


Company honor

Moreover, the company has been awarded "Model Integrity Enterprise", "Honest Private Business", "Zhejiang AAA-grade Credit Enterprise", and "Enterprise with Harmonious Labor Relation in Longwan District", Wenzhou Well-known Trademark and Zhejiang Well-known Trade Name.
