Integral pressure reversal operated spool valve AQ4Z60

Spool valves controlled by integral pressure NG6

Spool valve with 4 connections in a 5 chamber system with integral pressure reversal. Switch into the oposite switching position when the adjusted reversal pressure is reached. The reversal takes place e.g. in the end position of the stroke or when the load pressure is exceeding the adjusted reversal pressure. Cover with pressure reliefs for adjusting the reversal pressure. Precise spool fit, low leakage, long service life time. Spool made from hardened steel, body from high quality hydraulic cast steel.
