Precise flow control can guarantee regulating quality and product quality.
With fine dynamic stability, it can also ,maintain stable operation even at emergency great pressure difference.
With silencing design, it can reduce operating noise.
With less leakage and less air consumption of the locator, it can reduce energy consumption and improve economic benefit.
With high-precision flow feature, it can monitor the control status in procedures.
With simple structure, it is convenient for maintenance and operation.
With great anti-cavitation and erosion resistance, product life is long.
It is convenient for dismantling, and maintenance time is short.
With high-performance Cv combination, it can meet different actual demands.
Products have smaller weight and stronger anti-vibration capacity, product design is efficient and multi-functional.
With smaller volume, it can use space more effectively.
With high-precision flow feature, control process can be under computer analog control.
Many Cv values, performance values are improved.
With smaller valve weight and volume, operating costs are reduced.
With multiple spring actuator, structure is compact and output is great.
Low noise, cavitation resistance, smaller unbalanced force in value, stable operation under great pressure difference.
