Product Description

Overview of self-reliant pressure regulator with conductor
ZZYVP with conductor operation type self-operated pressure regulator is mainly composed of control valve, actuator and a pressure setting controller, simply said in general, direct acting type self-operated valve control accuracy is not high, two with the purpose of the controller is to increase the control accuracy. The valve without external energy, the use of the medium (gas) its own energy as a power source, the conductor into the detection actuator, to control the valve spool position, change the medium flow through the valve, so that the valve back-end pressure (type B) or front-end pressure (type K) to maintain at a constant value.


With the conductor self-reliant pressure regulating valve characteristics
The pressure setting value of the self-operated pressure regulating valve with a conductor can be realized on the conductor, and can be adjusted at will in operation. The control accuracy is about twice as high as that of the general direct operation acting self-operated valve, which is suitable for occasions with high control accuracy requirements; The detection and execution components are made of high temperature resistant materials. It can also be used in high temperature (200ºC) water steam situations without a condenser.

Self - operated pressure regulator with conductor
The conductor operation type self-reliant pressure regulator, when the pressure of the medium is raised, the pressure acting on the main valve diaphragm is greater than the above pressure, the spool moves up, the flow section is reduced, so that the pressure after the valve slightly decreases; Conversely, when the pressure of the regulated medium decreases, the pressure acting on the conductor diaphragm decreases.
