Seal type: Soft seal type
ZZYP Type Self-pressure regulating valve is a valve, valve seat, valve, balance springs and other components, is a kind of no external energy, the use of the media itself is adjusted automatically adjust to changes in pressure of the valve is based on the principles of mechanics accused medium introducing actuator generates force pushing the control valve element reaches the vertical displacement of the automatic adjustment of the valve before or after the constant pressure valve or pressure energy-saving products. The greatest feature of the product is able to work without electricity, no gas properties, pressure setting can be adjusted during operation. With quick opening flow characteristics, sensitive, good sealing performance, widely used in petroleum, chemical, power, light industry, printing and dyeing and other industrial equipment in gas, liquid, steam and other media pressure automatic control.
This series actuators are: film, piston type two; the role of the form: the valve before the pressure regulator (holding pressure relief type), after the pressure regulator valve (vacuum regulator type); attached compartment temperature in the condensation chamber use the following temperature ≤350 ℃. Depending on the working conditions can choose different structural types and different valve actuators, in order to achieve the best control effect.
