FAQ

The 'X' port is the external pilot port. Applying hydraulic pressure to this port opens the check valve, allowing flow from port B back to port A. Without pilot pressure, the valve blocks flow in this direction.

This valve is typically rated for a maximum operating pressure of 315 bar (approximately 4568 PSI) on all ports.

Yes, the SL 30 designation indicates it is a size NG30 valve, which corresponds to the ISO 4401-10 / CETOP 10 mounting pattern. It is designed for larger flow applications.
