Metal seat ball valve is designed for use in severe services such as high temperature, high pressure, and abrasive fluids found in Oil & Gas, Petroleum, Petrochemical, Chemical, Power Generation, Pulp & Paper, and Mining industries.

Ball valves are designed with extensive safety consider-ations for users. Blow-out proof stems, provision of locking devices and prevention of misalignment of lever hand provide safe handling in the field and trouble-free operation in the plant. Antistatic devices, fire safe seal design and cavity pressure relief features all assure the economic benefits of smooth, steady plant operation. advancements in low emission design features contribute to the global battle against fugitive emissions while greatly reducing costs by product loss.

Advantages:

1. Valve Design according to ASME 16.34, API6D,ASME B16.10, ASME B16.25, BS 5351

2. The service temperature of O-ring sealed normal temperature metal seated ball valve is 一 29 °C 一〜200 °C, and the graphite sealed metal seated ball valve is -29 °C 〜425 °C. The specific service temperature depends on the shell material and sealing surface material.

3. The valve seat adopts the elastic seal structure of bellows to effectively solve the leakage of sealing surface caused by the pressure and high temperature of the valve.

4. The low torque design of the valve effectively reduces the operating torque of the valve and prolongs the service life of the sealing surface

5. The moving parts such as valve seat, valve stem and ball are treated with surface wear-resistant technology to reduce the abrasion, abrasion and erosion of internal parts.

6. The surface of the ball and the valve seat adopts the supersonic spraying technology, which improves the hardness and wear resistance of the sealing surface, thus improving the service life of the valve and broadening the working range of the valve

Surface treatment of contact surface of valve seat

7. The valve sealing surface and overflow surface shall be sprayed with wear-resistant and anti-wear coating to reduce the erosion of medium metal parts and the sticking and corrosion caused by the accumulation of dirt in the medium

8. Anti-fire design according to API 607,Anti-static design according to BS 5351.
