  • INQUIRY
This valve is a actuator product which doesn't need any additional energy, using medium own energy to achieve automatic adjustment. The biggest feature of this product is that it can work in non-toxic, airless places, saving energy, and pressure settings can be textile, machinery manufacturing and residential buildings and other industries for the automatic controlling of a variety of medium like air, liquid and steam. It can be used in the temperature of ≤200℃ if equipped with condenser. The valve no need additional energy, equipment cost is low, suitable for explosive environments. Structure is simple, maintenance workload is small; Setting point is adjustable and adjusting range is wide, easy to adjust the user within the set range;Diaphragm actuator detection precision is higher than air cylinder actuator, action is sensitive, than the cylinder is the structure of high precision detection, action sensitive; Valve pressure balancing mechanism is equipped in valve, which makes the control valve has the advantages of sensitive response, precise controlling and high allowable pressure difference.
