Z2S16A,Z2S16B,Z2S16

- Porting pattern to DIN 24 340
- Leakage-free closure for one or two ports
- Sandwich plate valve, for use in
vertical stacking assemblies
- 4 cracking pressures, optional


Hydraulic pilot operated check valves type Z2S16 are sandwich plate
design. They are used for the leakage-free closure of one or two
service ports, even for long periods of time. Free flow occurs from A1 to
A2 or B1 to B2. Flow in the opposite direction is blocked.
When fluid flows from A1 to A2, the spool (1) is pressurised and is
pushed to the right, thereby opening the ball poppet valve (2) which
then opens the check valve(3).
In order to make reliable closure of the two check valves in the neutral
position, the service ports A1 and B1of the directional valve must be
connected to returning line .
