ZZYP Self-operated Pressure Control Valve
Overview:
ZZYP self-operated pressure control valve does not need external power supply, it utilizes the energy of mediums itself as a push force, and the force is guided into acting diaphragm chamber to automatically adjusting the movements of throttle parts. The valve has composite functions of measurement, action, control. It could work in non-gas, non-electricity conditions. It is widely used for automatically controlling with pressure-reducing, pressure-stabilizing, pressure-releasing of various gas, liquid, steam and other mediums in automatic control systems of petroleum, chemical industry, power station, light industry, etc. ZZYP series products consist of diaphragm type, piston type. According to acting modes, there are two types: after valve adjusting pressure for pressure-reducing purpose (type B), before valve adjusting pressure for pressure-releasing purpose (type K).
Specifications:
Size: DN 20~300
Pressure: PN16, 40, 64
Applicable temperature: -60℃~+450℃
Pressure of air supply: 0.5 MPa
Features:
There is no need to set external power supply. Self-operated pressure control valve could work in a condition of non-electricity, non-gas. So that it is convenient, also saving energy.
The pressure ranges are divided in details and they are intersecting with each other. So the adjusting accuracy is high.
The pressure pre-set value could be continuous changed during operating.
It adopts pressure balance principle, which makes the valve responds sensitively, being controlled precisely.
