Fleyenda CF8 CF8M Pneumatic Control Valves
Fleyenda CF8 CF8M Pneumatic Control Valves
The pneumatic control valve is composed of an actuator and an adjustment mechanism The actuator is the thrust component of the adjustment valve. The valve body is the regulating component of the pneumatic regulating valve It directly contacts the regulating medium to regulate the flow, pressure, temperature and other process parameters of the fluid. Without additional explosion-proof measures. Application: petroleum, chemical, electric power, metallurgy, etc.
Pneumatic Actuator Features
- Corrosion resistance: After 1,000,000 cycles of life test, the performance is still reliable. Using high-quality material and metal coating treatment, strong corrosion resistance and longer service life.
- Larger Size: Longer air cylinder, higher air consumption
- Low and High Temperature Resistance: Lower to 30℃/86℉~Up to 180℃/356℉
- Certificate Insurance: ISO 5211 and Namur international installation standard, easy to install and maintain.
