Pneumatic V-shaped regulating ball valve

Comprehensive information organization of pneumatic V-shaped regulating ball valve, combined with its technical characteristics, application scenarios, and market data:

1、 Product definition and core functions
Pneumatic V-shaped regulating ball valve is an industrial valve that drives a V-shaped notch ball to rotate through a pneumatic actuator, and has both flow regulation and shut-off functions. Its core advantages include:
Accurate flow control: The V-shaped notch design provides approximately equal percentage flow characteristics, with adjustable ratios up to 300:1.
Self cleaning and anti blocking: The V-shaped core and valve seat form a shear force, which can cut off fibers or solid particles and avoid medium accumulation.
High sealing performance: Metal valve seat leakage ≤ 10 ⁻⁶ x rated flow coefficient, suitable for high-pressure and corrosive media.
2、 Technical parameters and structure
Parameter specification range remarks
Nominal diameter DN25~DN600 (some support DN1000) flange/clamp type connection
Pressure rating PN1.6~10.0MPa (Class150~600) High pressure models require customization
Suitable temperature -29 ℃~450 ℃ High temperature type requires special materials
Drive mode: Pneumatic (single/double acting), can be equipped with a locator to achieve proportional adjustment
Key structure:
V-shaped core: The notch angle is usually 15 °~90 °, which determines the flow characteristics.
Execution mechanism: gear rack or piston type, response time 0.5-7 seconds.
3、 Typical application scenarios
Petrochemical industry: regulating corrosive media containing particles (such as crude oil and acid liquids).
Paper industry: Control high viscosity suspensions such as pulp and black liquor.
Electricity and Environmental Protection: Used for solid waste media such as desulfurization systems and sewage treatment.
