Pneumatic two stage ball valve principle
Pneumatic refers to the valve is automatic operation, power is compressed air;Two paragraph refers to the structure of the valve, that is, the body is composed of two parts connected by flanges, of course, there are other forms of a chip, three pieceTwo and two pieces mean one thing
By two pneumatic actuators and ball valve or butterfly valve, the piston stroke change additional cylinder, actuator and valve angle is stopped at a predetermined angle (45 degrees -90), so the valve flow can be adjusted. This device by two solenoid valve control valve flow. As the actuator uses the rapid exhaust and throttling function, so that the two segment ball valve has excellent switching characteristics. Slow open and close valve velocity, the fluid in the pipeline to change smoothly, not because of the impact of water hammer in the flammable fluid explosion, nor system flowmeter and other instruments damaged by the impact of the flow, it is suitable for the industries of petroleum, chemical industry, light industry, national defense and other control systems, especially suitable for oil storage and transportation system.
Two section type pneumatic ball valve, pneumatic piston two stage shut-off valve to achieve a two step or two step off the action of the cut-off valve is a special pneumatic valve, provides 0 degrees, 45 degrees, 90 degrees or 0 degrees, 90 degrees, three operating mode 180 degrees.
