ZZYP self pressure regulating valve is a kind of without external energy, using controlled the media's own energy when the power source, is introduced to perform film chamber to produce thrust, throttle control element to achieve automatic adjustment. Comprehensive function ZZYP control valve has the measurement, implementation, control. Available in no gas, no electric place. Widely used in petroleum, chemical, power, light industry, printing and dyeing industry in the automatic control system of gas, liquid and various equipment steam medium pressure regulator (for deceleration, pressure regulating valve after the pressure relief, pressure) (for the valve before the pressure adjustment automatic control

ZZYP - 16 k/B self-reliance type pressure regulator when install and use, should put add cold water condenser, open the by-pass pipe cut-off valve, expel a mixture of condensed water and soda in line, in case of the relief valve opens to produce water there is damage to the valve, when no abnormal phenomenon, slowly turn adjusting screw clockwise, the outlet pressure to set the desired pressure (the table after the valve pressure shall prevail), after adjustment, the lock nut back tightly, screw on the cover. Pressure reducing valve should be installed before the filter, debris into the pressure reducing valve, in case the medium influence its performance. Should have a straight pipe before and after the installation of the pressure reducing valve, valve in front of the straight pipe length is about 600 mm, the valve after the straight pipe length is about 1 mm. General relief valve must require import and export pressure differential acuity 0.2 Mpa. Pressure reducing valve usually has a variety of specifications such as DN15 ~ DN400, valve before and after the work pressure respectively < 1 ~ 0.5 MPa and 0.1 MPa, the pressure regulating range of error of plus or minus 5% ~ 10%.
