1. Only hand wheel drive, no need to match other driving components, low cost, widely used.

2. It has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy installation and easy disassembly.

3. When the valve is fully opened, the flow resistance coefficient is very small, and the valve will eliminate the function of the valve disc and the dirt on the sealing surface every time the valve is opened and closed.

4. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.

5. It is widely used in oil and water steam pipelines such as petrochemical industry and thermal power plants to connect or cut off the intermediate quality of pipelines. The sealing surface of the opening and closing device has compact structure and reasonable design.

Q: Does the force applied to the handwheel need to be large?

A: No, the force applied to the handwheel will be ≤360N.

 

Q: Does the inlet need to have a straight pipe section?

A: No need, this valve front and rear without straight pipe section.

 

Q: What kind of packing and shipping will be used?

A: We will pack and ship according to your specific requirements.

 

Q: Can I request special configuration?

A: In accordance with the requirements of the specification, we will meet your needs.

 

Q: What is the temperature and pressure scale used for materials?

A: Check nominal pressure at known working pressure and working temperature.

 

Q: What should be done to LCB materials to bring them up to standard for low temperature impact?

A: Do normalizing + tempering treatment. And then I'm doing the cryogenic treatment.

 

Q: How many gaskets are often used?

A: Often used gaskets are non-metallic gaskets, metal flat gaskets, metal ring gaskets, tooth combination gaskets, coated gaskets, wound gaskets, composite gaskets.

 

Q: What should be considered when making low temperature valves?

A: First of all, consider the low temperature brittleness of the material, consider the sealing performance of the filler at low temperature to prevent abnormal pressure.
