Pressure Reducing Valve/ CETOP3
Sandwich pressure reducing valves FZDR6 are commonly used in hydraulics to reduce pressures in one segment or branch of circuit. These are 3-way direct operated valves in sandwich design suitable for vertical stacking with CETOP3 (ISO4401) mounting interfaces. The reduced pressure (secondary pressure) can be monitored through gauge port available as standard on the valve.
These valves are direct operated type with pressure reducing in P or A lines as option. The standard valves are internally piloted with external pilot oil return. When the primary pressure is lower than the secondary pressure setting, the oil flows from P to P1 without any intervention of the reducing valve, but the pressure is monitored through internal pilot line. When the primary pressure increases beyond the secondary pressure setting, the secondary pressure is maintained as per setting.
In the event of fluctuations in actuator side and secondary pressure increases, the valve relieves the additional pressure and functions as a reducing cum relieving valve.
