ZZYP Self Operated Pressure Regulating Valve Overview
ZZYP Self Operated Pressure Regulating Valve produced and sold by Baigang valve group is a need without additional
energy, the use of the controlled media its own energy as a power
source, the introduction of the executive chamber~produce thrust~control
the throttle element movement~automatically adjust. With measurement,
implementation, control of the integrated features. Available in no gas,
no electricity place. Widely used in petroleum, chemical, power plants,
light industry, printing and dyeing industry, automatic control system
for a variety of equipment, gas, liquid and steam media deceleration
pressure, regulator (for the valve pressure regulator) relief pressure,
Pressure control) automatic control. According~the user's different
conditions can choose different spool structure and different
implementing agencies, in order~achieve the best control effect.

Pressure
closed type: for the valve pressure regulator, when the valve pressure
increases, the valve closed, in order~achieve decompression, the purpose
of regulating.
Pressure type: for the valve pressure regulator, when the valve
pressure increases, the valve opens, in order~achieve pressure relief,
the purpose of regulating.
