Three-Way Flanged Ball Valve Stainless Steel Carbon Steel Class 150 300 600 for Petrochemical Water Treatment China Manufacturer

Standardization of Materials and Manufacturing

Standardization of Materials and Manufacturing
01
The valve body is made of ASTM standard stainless steel or carbon steel, which is corrosion-resistant and suitable for various media such as water, oil, acid and alkali.
02
Compliant with international standards such as API and ANSI, suitable for mainstream pipeline systems worldwide.

Safety redundancy function

01
Automatic pressure relief in valve chamber
When the abnormal pressure rises, the valve seat moves backwards and disengages from the ball to release pressure. After pressure relief, it automatically resets to avoid the risk of bursting.
02
Anti static and anti valve stem detachment design
Some models are equipped with bottom mounted valve stem structures and anti-static devices to ensure safe operation.

Convenient operation and simple maintenance

01
Flexible driving mode
supports manual, electric, and pneumatic (single acting/double acting) control, and single acting can maintain the preset state in case of power source failure.
02
Modular design
Components such as valve seats and sealing rings can be disassembled and replaced, eliminating the need for overall disassembly during maintenance and reducing downtime costs.

Low flow resistance and high flow efficiency

Low flow resistance and high flow efficiency
01
Full diameter or reduced diameter spherical design, matching the inner flow channel with the pipeline, with low medium flow resistance (close to the same length of straight pipe section), reducing energy consumption.
02
Large circulation cross-sectional area, suitable for high flow scenarios such as chemical and petroleum transportation.

High sealing performance and wear-resistant design

High sealing performance and wear-resistant design
01
Sealing material optimization: PTFE, RTFE or metal hard seal valve seats are used, with strong corrosion resistance, suitable for high temperature (-196 ℃~550 ℃) and high pressure (PN16~PN64) working conditions.
02
Self compensation function: The valve seat is preloaded by a spring or butterfly spring, and automatically compensates for wear, maintaining sealing performance and extending service life.

Multi directional flow control capability

01
T-shaped and L-shaped core designs
T-shaped ball valve: realizes the diversion, merging or flow direction switching of three orthogonal pipelines, suitable for complex medium distribution scenarios.
02
L-type ball valve
only connects two vertical pipelines, used for single flow switching or medium distribution.Driven by electric or pneumatic actuators, the ball can be rotated 90 degrees to complete the operation, with fast response speed and support for remote automation control.

Integrated structure and lightweight design

Integrated structure and lightweight design
01
Adopting integrated casting or forging valve body, with few flange connections, compact structure and high reliability, reducing the risk of leakage.
02
Lightweight design reduces overall weight (some models can reduce weight by 30%) while maintaining high strength, suitable for space constrained pipeline systems.
