FEP-Lined Self-Operated Micro-Pressure Regulator(ZPL630),It’s no need an external power supply or air source, and uses the pressure of the medium of the controlled pipeline as a power source to control the position of the valve spool, so as to change the pressure difference and flow at both ends, to achieve the purpose of controlling the pressure stability at outlet side (B-Modle) or pressure relief at inlet side (K-Modle). It has the advantages of quick response, good sealing performance, small pressure fluctuation, etc., and is widely used in micro-pressure control in various industrial equipment.
The acting form of ZPL630 have 2 typies,As following:
1.Outlet Side Pressure Regulating Valve (B-Modle):The valve’s spool initial setting position: OPENED.
2.Inlet Side Pressure Regulating Valve (K-Modle):The valve’s spool initial setting position: CLOSED.
