Air Pressure self operated regulator valve is mainly used to control pressure, temperature and flow of vapors and other industrial liquids. During its work, it can carry out the control through the medium itself without the need of using external energy.
Series - 150 To 300
The product is provided with the built-in bellows balanced structure with excellent control performance and agile response to medium changes. This product can serve as an important part in a system to ensure efficiency and stability of the system through its outstanding performance.
Design Features
- Self-reliance type pressure regulating valve does not need additional energy, can work in the absence of electric airless place, convenient and save the energy
- Pressure piecewise range is small and cross each other, high precision of adjustment
- Pressure setting can be set in a continuous during operation
- The ratio of front and back pressure is 10:1~10:8
- High detection precision, sensitive action
- Using pressure balance mechanism, the regulator is responsive, precise control
