ZZYP Self-operated Regulating Valve Overview
ZZYP Self-operated Regulating Valve produced and sold by Baigang valve group is a need without external
energy, the use of the controlled medium itself as a power source, the
introduction of the executive chamber~produce thrust~control the
movement of throttling components~achieve automatic adjustment. 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.
