BGTWF Type Pneumatic Butterfly Valve  

1.Summary

  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.

2.Introduction

According to many years’ valve manufacturing experience, we developed fully lined butterfly valve to replace gate valve, to meet high-performance, water conservation, energy needs. It’s with simple structure and excellent performance, and is widely used. The product can be installed in the petroleum, chemical, food, pharmaceutical, textile, paper, water, electricity, shipbuilding, urban drainage, metallurgy, energy and other systems, all corrosive and non-corrosive gas, liquid, semi-liquid, solid powder as the pipeline, such as regulation and closure devices. 
Fully lined butterfly valve pneumatic flange 
BGTWF pneumatic fully lined butterfly valve with flange is composed of full-lined butterfly valves and BGT pneumatic actuator. 
BAWWF pneumatic Fully lined butterfly valve with flange is composed of full-lined butterfly valves and BAW pneumatic actuator.

3.Feature

1.rubber vulcanization in the body inner wall, the rubber in contact with the body wall at no leakage. 
2.tight rubber lining, avoiding redundant and movement, highly reliable and durable. 
3.seal design of the valve is reasonable, small torque, high pressure seals, and no bubble. 
4.the valve is flanged, neutral, and can be used for pipe ends and arbitrary demolished when maintenances.

4.Performance

 Note: The length of the structure is accordance with ISO5752 standards.
