FAQ

What is the function of a double pilot operated check valve like the ZW-DM10?

It allows free flow in one direction and blocks flow in the opposite direction. The blocked flow can be opened by applying hydraulic pilot pressure to the respective pilot port, which allows a connected actuator (like a hydraulic cylinder) to be held securely in position and then moved when required.

What does the NG10 (CETOP 5) designation mean for installation?

NG10 (Nominal Size 10) and CETOP 5 are standardized mounting patterns for hydraulic valves. This ensures that valves from different manufacturers with the same designation are interchangeable, simplifying design, installation, and maintenance.

How does the pilot pressure ratio affect the valve’s operation?

The pilot pressure ratio determines how much pilot pressure is needed to open the check valve against a certain load pressure. A lower ratio requires higher pilot pressure to open the valve, which can be important for stability in certain circuits.
