Imported pneumatic regulating ball valve
Imported pneumatic regulating ball valve product overview:
American YLOK imported pneumatic regulating ball valve is a high-performance regulating ball valve, which is composed of a ball valve and a pneumatic actuator, a valve positioner and other accessories. It adopts intelligent control and positioning and has precise control functions. The pneumatic regulating ball valve can control the rotary opening of the ball valve core according to the input 4-20mA control signal and 0.4～0.7bar air source, and realize the precision adjustment of the pipeline medium pressure, flow, temperature, liquid level and other parameters. Adjustable pneumatic ball valve not only has strong adaptability and good sealing performance, it is widely used to control pulp, sewage, suspended media containing fibers and solid particles, high-temperature steam, dry gas and other media.
Imported pneumatic regulating ball valve performance specifications:
Single-action: Normally open or normally closed type, and return to the original position when the air is open or the air is closed.
Double acting: air-to-close type, air-to-close type, the valve position remains unchanged when the air is lost.
Available accessories:
Positioner, solenoid valve, air filter pressure reducer, retaining valve, travel switch, valve position transmitter
Manual mechanism: In case of air source failure, the valve can be opened and closed manually.
