Liquid Ball Valve Gas Ball Valve Stainless Steel Carbon Steel API 6D for Oil Gas Chemical Water China Manufacturer

Liquid Ball Valve, Gas Ball Valve

Liquid ball valve

A valve designed specifically for liquid media, which can be opened and closed by rotating a ball with a through-hole. It is made of corrosion-resistant materials (such as stainless steel and PTFE seals) and has an anti leakage structure. It is suitable for liquid transportation systems such as water, oil, acid and alkali, and is resistant to high pressure with reliable sealing.

Gas ball valve

Valves specifically designed for gas (natural gas, liquefied gas, etc.), with anti-static and fire-resistant treatment on the ball and seat, made of copper alloy or stainless steel, with dual sealing and explosion-proof design, strictly complying with gas safety standards to prevent gas leakage and explosion risks.

Medium resistance and long lifespan

Medium resistance and long lifespan
01
Copper alloy or stainless steel material is resistant to hydrogen sulfide corrosion and suitable for impurity containing gases such as natural gas and liquefied gas.
02
The sealing pair is resistant to particle erosion and has a lifespan 2-3 times that of ordinary valves, reducing frequent replacement.

Diversified control mode

Diversified control mode
01
Support manual, pneumatic, and remote control (such as RTU signals) to meet the operational needs of different scenarios.
02
Low torque design, requiring only 90 ° rotation for opening and closing, suitable for long-distance pipelines and high-risk areas.

Leak prevention and sealing enhancement

Leak prevention and sealing enhancement
01
Double sealing structure (metal+soft seal), the valve seat is made of elastic material, and the sealing force increases with the medium pressure.
02
Floating ball or spring preloaded valve seat design compensates for wear and maintains long-term sealing reliability.

Security protection and emergency shutdown

Security protection and emergency shutdown
01
Equipped with pressure sensitive components, it automatically cuts off the gas source in case of overpressure or abnormal pressure drop rate to prevent explosion accidents.
02
The valve stem anti flying design and fireproof structure ensure the integrity of the valve under extreme working conditions.

Convenience of operation and maintenance

Convenience of operation and maintenance
01
Rotate 90 ° to quickly open and close, support manual or automated control, easy to operate.
02
The upper structure or detachable valve seat facilitates online replacement of seals and reduces maintenance costs.

Low flow resistance and high pressure adaptation

Low flow resistance and high pressure adaptation
01
Full bore channel design, low fluid resistance, close to pressure loss in straight pipe sections, improving transmission efficiency.
02
The valve body has a compact structure and can withstand high-pressure conditions (such as chemical and petroleum pipelines). The sealing surface is isolated from the medium to reduce erosion.

Corrosion resistant materials and sealing structures

Corrosion resistant materials and sealing structures
01
Adopting stainless steel valve body and PTFE corrosion-resistant sealing ring, it can withstand long-term corrosion from liquid media such as water, oil, acid and alkali.
02
Bidirectional elastic sealing design enhances sealing performance with increasing medium pressure, effectively preventing leakage.
