Product Description

Self-operated Pressure and Differential Pressure Conbined Control Valve
(ZZYVP)

Summary:
Self-operated pressure and differential pressure combination valve has no additional energy, and it can work in the place without electricity and gas, so it is convenient and energy saving. It is mainly composed of pressure valve, differential pressure valve, two actuators and two sets of pressure spring. It is suitable for non-corrosive liquids, gases and steam, in the system pipe pressure or differential pressure control. Pressure segmentation range is fine and cross each other, the adjustment accuracy is high, according to the principle of priority action, it can not control two parameters at the same time.

Features:
Self-operated pressure and differential pressure combination valve can be a number of combination control. It requires no external control instrumentation. The system is simple and low-cost, and the pressure setting value can be continuously set during operation. The pressure balancing mechanism is adopted to make the regulating valve more responsive and control more accurate.
