ZZYV Self Operated Micro Pressure Regulator, PN16, PN25, PN40, PN63

ZZYV Self operated micro pressure regulator is split into single seat self operated pressure regulator and double seat self actuated micro pressure control valve.It doesn't need exterior energy,and uses the power from the controlled medium because the source of energy.Self operated pressure regulator introduces the actuator to manage the positioning of the spool to alter the intercept area, thus altering the pressure difference and flow at both sides, and having reason for pressure stability (downstream type) or pressure relief (upstream type).Self operated micro pressure regulator is broadly utilized in micro pressure charge of gases in a variety of industrial equipments.

The Features of Self Operated Micro Pressure Reducing Regulator:

1. The pressure set point could be adjusted on-site inside the pressure adjustment range

2. The spring could be replaced based on the changes of needs on-site, so the pressure adjustment range could be rapidly altered inside a certain range

3. Self-operated single-seat micro pressure control valve generally adopts rubber diaphragm because the pressure balance component. The modification of upstream pressure has no effect on the pressure from the valve plug, greatly accelerating the response speed from the valve, thus increasing the control precision from the valve

4. The valve stem seal adopts a non-packing design, which greatly cuts down on the friction and also the upper seal is completely reliable

5.The self operated double-seat micro pressure regulator adopts self-balancing double-sealed double-seat valve plug because the throttle piece, that is appropriate for occasions with large valve diameter

6. The actuator adopts rubber diaphragm because the discovering component, that has small resistance, quick response, high adjustment precision, and incredibly micro pressure changes is going to be thought with the diaphragm amplification

7.Once the upstream pressure is >0.1 MPa, or even the medium is corrosive to rubber, or it's high temperature medium, the pressure balance element and also the actuator recognition element may use metal bellows.
