Pneumatic Segment Ball Valve

Pneumatic Segment Ball Valve

As the professional manufacture, we would like to provide you Pneumatic Segment Ball Valve. And we will offer you the best after-sale service and timely delivery. Pneumatic three-stage ball valve SQ641F pneumatic three-stage ball valve / pneumatic segmented ball valve / three-stage pneumatic ball valve / three-stage pneumatic cut-off valve / three-stage pneumatic ball valve / pneumatic two-stage ball valve / pneumatic piston three-stage cut-off ball valve / pneumatic three-stage loading ball valve / pneumatic three-stage ball valve / pneumatic three-stage stainless steel ball valve is a cut-off valve that can achieve two-step open or two-step close action, is By the three-stage that is: 0°- 45°- 90°or 0°- 90°- 180°segmented three-stage pneumatic actuator + ball valve composition.

Open valve stage: 20% open in the first stage, wait for stabilization, then open all in the second stage. Closing is also the same, 80% closed in the first stage, and when stabilized, all closed. By changing the piston stroke of the additional cylinder, the actuator and the valve angle are stopped at a pre-set angle (45°-90°), so that the valve flow is regulated. This device relies on two solenoid valves to control the flow of the valve. Due to the fast exhaust and throttling function in the actuator, the two-stage ball valve has excellent switching characteristics. So that the opening and closing speed of the valve is slowed down, so that the fluid in the pipeline changes smoothly, will not produce water hammer phenomenon due to the impact of the explosion of flammable fluids, and will not damage the flow meter and other instruments in the system due to the impact. Optional double-acting and single-acting (in case of failure, the valve automatically closes), can be equipped with a handwheel mechanism (in case of power failure, it can be manually operated), and thus is suitable for flow control systems in petroleum, chemical, light industry, national defense and other industries, especially for oil storage and transportation systems.

Three section cylinder parameters: three section cylinder has two models 0°-45°-90°and 0°-90°-180°, after the air inlet piston to both ends of the movement is designed at both ends of the auxiliary piston to produce mechanical restrictions to achieve the intermediate position, can be directly used outside the two ends of the adjustment bolt is easy to adjust the intermediate position angle, such as 20°, 30°, 50°, 75°and 95°, 120°, 130°, 150°, 175°, etc.
