Pneumatic Butterfly Valve
Pneumatic valve is a pneumatic valve angle of 90 ° , typically used to control high flow, low dropout fluids. Butterfly is characterized by small size, simple structure, small space required for installation, and low cost. Since the smooth flow path valve resistance coefficient, the higher the flow obtained is therefore suitable for high viscosity, with the fibers, particles and the sediment containing the regulation and pulp medium flow.
Pneumatic control valve can be chose different materials lining body and different materials valve plate according to different media.
According to the requirements of the production process, there are wafer centre line butterfly valve, flanged full-lining butterfly valve, triple offset metal-sealing butterfly valve, air butterfly valve.
The butterfly valves above all could open 90 ° , are characterized by approximately equal percentage, large flow capacity, greatly exceeds its rated value of the same caliber Kv other valves.
Pneumatic butterfly valve is composed by butterfly valve and pneumatic actuator, which can automatically adjust the temperature, pressure and flow rate of the medium. Pneumatic triple eccentric metal sealing butterfly valve could shut off and achieve zero leakage.
Feature
1. Small, light, easy installation and maintenance.
2. Simple structure, compact, 90 ° Swivel open and close rapidly, small operating torque, energy saving.
3. The opening and closing times can be up to tens of thousands of times, long service life.
4. Flow characteristics tend to be linear, with better performance.
5. Completely sealed, zero gas leak test.
6. Different materials could be applicable for a variety of media.
