Sandwich plate valve Porting pattern according to ISO 4401-05-04-0-05 4 pressure ratings 4 optional adjustment types:• Rotary knob• Sleeve with hexagon and protective cap• Lockable rotary knob with scale• Rotary knob with scale Check valve, optional (versions "A" and "B") Pressure gauge connection
Pressure valves of type ZDR 10 V are pilot-operated pressure reducing valves in sandwich plate design. They are used for reducing a system pressure.
The pressure valves basically consist of pilot control valve (1) and housing (2). The secondary pressure is set via the adjustment type (4).
Pressure reduction in channel P➀ ("P")
In initial position, the valves are open. Hydraulic fluid can flow from channel P➁ to channel P➀ without restrictions.
The pressure in channel P➀ acts simultaneously at the main spool (6), via the bore (5) at the spring-loaded inside of the main spool (6) and via the nozzle (9) on the pilot poppet (8).
If the pressure in channel P➁ exceeds the value set at the compression spring (7), the pilot poppet (8) opens.
Hydraulic fluid flows from the spring-loaded inside of the main spool (6) via the nozzle (9) and the pilot poppet (8) into the spring chamber (10). The main spool (6) assumes its control position and keeps the value in channel P➀ set at the compression spring (7) constant. The pilot oil return from the spring chamber (10) is realized via port TA.
Pressure reduction in channel A➁ and B➁ ("A" and "B")
For free return flow from channel A➁ to A➀ / B➁ to B➀ , a check valve can be optionally installed (not possible with version "P").
A pressure gauge connection (3) enables control of the secondary pressure.
