1. The shell is cast, which can make the appearance of complex shape and is more beautiful than the forged shell.

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 open, the flow resistance coefficient is very small, and the valve will eliminate the dirt on the function of the valve disc and 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. Simple shape, short structure length, good manufacturing process, wide range of application.

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

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

 

Q: What are the advantages of casting?

A:

1. Can produce complex shape parts Casting is a mold process, can manufacture complex shape parts, and the number is large, light weight, making the manufacturing cost is relatively low. It is widely used in the manufacture of various mechanical parts and appliances.

2. The casting process is flexible and can change the properties of the material, size and shape of the casting to meet the requirements of different fields. The traditional processing method requires the entire processing process to be reformulated, so the casting has higher efficiency and flexibility.

 

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: Does the valve have a flight-proof function?

A:Yes, under no circumstances does the stem have the possibility of ejection due to internal pressure.

 

Q: What are the main functions of the valve?

A: The main purpose of the valve is to be installed in various pipeline systems, as a pipeline control accessory, mainly used to change the passage section to control fluid pressure, flow and direction, such as truncation, adjustment, check, shunt, safety, decompression and so on.

 

Q: What are the requirements for stuffing boxes?

A: The standard has requirements for the width and depth of the stuffing box.

 

Q: What is the intergranular corrosion of rusty steel?

A: When Austenitic stainless steel is insulated at 450 ~ 850℃ or slowly cooled, Cr23C6 rich in Cr is precipitated on the grain boundary. The matrix around it produces chromium-poor zone, resulting in the formation of corrosion galvanic cell caused by.
