Z2S 16 Pilot Operated Check Valve
The Bosch Rexroth Z2S 16 is an industrial-grade, pilot-operated check valve in a sandwich plate design used for the zero-leakage, drop-free locking of one or two actuator ports. It is engineered as a modular stacking component (Size 16, NG16) that sits vertically between a directional control valve and a standard subplate.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
