Pneumatic valve

Stainless steel V-shaped regulating clamp ball valve is a right angle rotary regulating valve that adopts clamp installation, consisting of V-shaped ball body, valve seat, valve stem, and piston type pneumatic actuator and other components. Its core structure includes a sphere with a V-shaped notch, which is driven by an actuator to achieve 0 ° -90 ° rotational motion and accurately adjust the cross-sectional area of the medium flow. The valve body is made of stainless steel material, which has the characteristics of corrosion resistance and high temperature resistance, and is suitable for complex working environments.

Structural design characteristics

1. ‌V型球体与阀座‌The surface of the ball core adopts precision machined V-shaped notches, matched with hard or soft sealed valve seats to ensure high sealing performance (leakage level GB/T4213 IV-VI). During the opening and closing process, the V-shaped incision forms a shear effect with the valve seat, effectively cutting off fiber impurities and preventing medium deposition.

2. ‌对夹式安装‌Compact structure, small volume, clamped between pipeline flanges with bolts during installation, suitable for working conditions with limited space.

3. ‌活塞式气动执行器‌Adopting a double acting or single acting cylinder structure, the gear transmission design has a large output torque and supports fast response (opening and closing time ≤ 2 seconds). The actuator is equipped with a manual operating mechanism and limit switch for easy on-site debugging and status feedback.

Performance advantages

• ‌精准调节‌The flow characteristics are approximately proportional, with an adjustable ratio of 300:1, suitable for large-scale flow control.

• ‌抗堵塞能力‌The V-shaped sphere and flow channel design can handle suspensions or powdered media containing fibers and particles, avoiding blockages.

• ‌高可靠性‌Integrated casting process for valve body, high compressive strength; The metal valve seat has self compensating function, extending its service life.

Application scenarios

This valve is widely used in the fields of papermaking, wastewater treatment, chemical engineering, and energy, especially for flow regulation of scaling prone media such as pulp and wastewater. In the automation control system, it can be linked with pressure and temperature sensors to achieve emergency shutdown or closed-loop control of process parameters.

By driving the actuator with air source pressure, the valve can be remotely or automatically controlled, meeting the dual requirements of safety and efficiency in industrial scenarios
