Working Principle (Filter Regulator with Backflow Function)
AW10
AW20K to AW60K
When the inlet pressure is higher than the regulating pressure, check valve w closes and operates as a normal regulator (Figure 1).
When the inlet pressure is shut off and released, check valve w opens and the pressure in the diaphragm chamber q is released into
the inlet side (Figure 2).
This lowers the pressure in diaphragm chamber q and the force generated by pressure regulator spring e lifts the diaphragm. Valve r
opens through the stem, and the outlet pressure is released to the inlet side (Figure 2).
When the inlet pressure is higher than the regulating pressure, the check valve operates as a normal regulator (Figure 1).
When the inlet pressure is shut off and exhausted, any inlet pressure applied to valve q will be lost. The force for seating valve q is the
valve spring w force only. When the valve q is opened using the outlet force, the outlet pressure will be exhausted at the inlet side.
(Figure 2)
When the set pressure is 0.15 MPa or less, valve q may not open due to the force of valve spring w.
