FAQ

What are the functions of the included CXFA and PPFB cartridge valves?

The CXFA is a pilot-assisted counterbalance valve used to control overrunning loads and provide thermal relief. The PPFB is a pilot-to-close check valve, which blocks flow in one direction until a pilot pressure signal is applied to open it.

What are the typical applications for this type of valve assembly?

This combination is often used in hydraulic circuits for controlling cylinders or motors, for example, in boom lifts or clamping systems, to ensure smooth operation and prevent load dropping in case of pressure loss.

The block is marked “SOL. VALVE”. Can a solenoid valve be fitted to this manifold?

The marking “SOL. VALVE” with an arrow indicates a port that is likely intended for connection to or interaction with a solenoid valve in a larger circuit. While this specific block does not have a cavity for a screw-in solenoid cartridge, it is designed to be part of a system that includes one.
