ZZYP ZZYP-16 ZZYP-40 Self-actuated control valve is an energy-saving control device that does not require external driving energy, relies on the pressure of the regulated medium itself as the power source and its medium pressure change, and automatically adjusts according to the preset set value. It integrates many functions of detection, control and execution into one valve, forming an independent instrument control system.

Energy saving automatic control system without additional driving energy, low equipment cost, suitable for explosive environment; Simple structure and small maintenance workload; The set point is adjustable and the range is wide, which is convenient for users to continuously adjust within the set range; Compared with the cylinder type mechanism, the diaphragm type actuator has higher detection accuracy and sensitive action; The pressure balance mechanism is adopted in the valve to make the regulating valve responsive, precise in control and large in allowable differential pressure.
