Feature:
-Limiting of main or plate flow with two service ports
-Sandwich plate design
-Meter-in meter-out control
Functional Description, section:
Valves type Z2FS are double throttle/check valves in sandwich plate design. They are used to limit main or pilot oil flow at one or two service ports. Two symmetrically arranged throttle/check valves limit flow (by maens of adjustable throttle spools) in one direction and permit free return flow in the other direction.
Main flow limiting: fitted between the directional valve and the subplate
Pilot flow limiting: fitted between the main valve and the pilot
valve.
