1. The five-piece flat gate valve structure without diversion hole is adopted. The five-piece structure of the gate adopts the telescopic structure, which greatly reduces the weight of the gate.

2. Significantly reduce the friction between the main gate and the seat in the opening process, further reduce the opening and closing torque, avoid the phenomenon of the main gate stuck, and extend the service life of the valve.

3. The upper end of the main gate is fixed to the valve stem, and there is a V-shaped bevel between the main gate and the contact surface of the slave gate, which greatly enhances the sealing effect

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

5. The valve is suitable for a variety of media, including water, oil, gas, etc., widely used in petroleum, chemical, metallurgy, electric power and other industries.

Q: Why choose the Five-piece flat gate valve without diversion hole?

A: Because it is less labor when it is opened and closed, it is compared with the globe valve, because whether it is open or closed, the direction of the ram movement is perpendicular to the direction of the medium flow.

 

Q: Are there compensating elements between the RAMS?

A: The inclined plate has a built-in tension spring and a fixed block, wherein the tension spring is stretched when the inclined plate is stretched;

 

Q: No sliding friction between the valve seat and the valve seat during the closing process to avoid wear of the sealing surface?

A: In the process of the wedge frame rising with the valve stem, the two inclined plates are unable to support the main gate. In order to make the main gate free from the seat, the two inclined plates are pulled back to the position by the contraction of the tension spring, which significantly reduces the friction between the main gate and the seat during the opening process, further reduces the opening and closing torque, avoids the phenomenon of the main gate sticking, and extends the service life of the valve.

 

Q: Can I request special configuration?

A: According to the specifications, we will meet your needs

 

Q: What does API mean?

A. It's the American Petroleum Institute.

 

Q: What is APIQ1?

A: It is the Quality Outline Specification for the Petroleum, Petrochemical and Natural Gas Industry.

 

Q: What types of valves does API6D contain? What are they?

A: API6D contains 4 types of valves, namely gate valves, ball valves, plug valves and check valves.

 

Q: What is the difference between API600 and API6D?

A: API600 is the "Steel Gate Valves with bolted caps for the Petroleum, and Natural Gas industries" standard, and API6D is the "Pipeline valves" standard, which includes four categories of valves, namely gate valves, ball valves, plug valves and check valves.

 

Q: If the inspection finds that the product does not meet the API requirements, what will happen to the API mark on the product?

A: Cancel the API identification.

 

Q: Which market is the CE certificate required for valve export?

A: The EU market.

 

Q: What is the difference between CE, API and ISO quality systems?

A:

API liaises with all sectors of the petroleum industry on standards, recommended practices, RPS, API newsletters and specialty publications

ISO: The international quality system is the organization, responsibilities, procedures, processes and resources for implementing quality management

CE: European goods indicate that they comply with the requirements expressed in a series of European directives on safety, health, environmental protection and consumer protection.
