ZZYP ZZYP-16 ZZYP-40 ZZYP-64 Self-actuated control valve

Overview of ZZYP ZZYP-16 ZZYP-40 ZZYP-64 Self-actuated control valve

ZZYP ZZYP-16 ZZYP-40 ZZYP-64 Self-actuated control valve is an energy-saving control device that does not need additional driving energy, relies on the pressure of the regulated medium as the power source and its medium pressure change, and automatically adjusts according to the predetermined setting value. It integrates many functions of detection, control and execution in one valve, and forms an independent instrument control system

Working Principle of ZZYP ZZYP-16 ZZYP-40 ZZYP-64 Self-actuated control valve

The regulating valve is composed of electric actuator or pneumatic actuator and regulating valve. The regulating valve is usually divided into straight through single seat regulating valve and straight through double seat regulating valve. The latter has the characteristics of large flow capacity, small imbalance and stable operation, so it is usually especially suitable for occasions with large flow, high pressure drop and less leakage .The regulating valve is used to regulate the flow, pressure and liquid level of the medium. The opening of the valve is automatically controlled according to the signal of the regulating part, so as to achieve the regulation of medium flow, pressure  and liquid level. The regulating valve is divided into electric regulating valve, pneumatic regulating valve and hydraulic regulating valve

Features of ZZYP ZZYP-16 ZZYP-40 ZZYP-64 Self-actuated control valve

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