Imported pneumatic regulating butterfly valve (Germany Robert brand)
Product details
Germany Robert imported pneumatic regulating butterfly valve is composed of a high-precision pneumatic actuator and a high-performance sealing butterfly valve body. The pneumatic regulating butterfly valve has a simple and compact structure, is easy to process, can be easily made into a large diameter, has a self-cleaning function, has a small resistance coefficient and has a large flow capacity. In addition, it is equipped with a valve positioner, and the operation can be controlled by inputting the control signal () and the air source. Equipped with an electrical valve positioner or solenoid valve, air filter pressure reducer, and limit switch (valve position return device), the proportional adjustment and two-position cut-off control of the fluid medium in the process pipeline can be realized, thereby achieving the control of the fluid medium. Automatic control of flow, pressure, temperature, liquid level and other parameters. It is the best device for regulating flow and cutting off fluid in automatic control systems.
Product Features
The butterfly valve has a simple structure, compactness, light weight, easy installation and disassembly, and convenient maintenance
. It has small operating torque and is the smallest operating torque among all valves. It closes quickly
, has a simple structure, small volume, light weight, small flow resistance, large flow coefficient and good sealing performance. Large adjustment range
The sealing surface of the butterfly plate is made of cobalt-based hard alloy surfacing. The sealing surface is wear-resistant, has a long service life
, is corrosion-resistant, and has super durability and reliability.
