FAQ

What is the function of a pilot-operated check valve like the Z2S 10?

It blocks flow in one direction like a standard check valve but can be remotely opened by a pilot pressure signal to allow reverse flow. This is used to lock a hydraulic cylinder or motor securely in position.

What does NG10 (CETOP 5) specify?

NG10, also known as CETOP 5, refers to a standardized mounting pattern and port size for hydraulic valves, as defined by ISO 4401. This ensures interchangeability between components from different manufacturers that adhere to the same standard.

What is the typical maximum operating pressure for this valve?

The Z2S 10 series is generally rated for a maximum operating pressure of 315 bar (approximately 4568 psi). However, it is always best to consult the specific manufacturer datasheet for the exact pressure and flow ratings for your application.
