Thanks. I'll give that a try when I'm in the workshop. Still very odd how two valves (of different brands even more so), are behaving this way. Will be very coincidental if I find the incorrect spool has been installed in both.

Thanks very much for the replies. Coils are DC, and operating correctly. Manually overriding them achieves the same result, so it's not a coil issue. The coil plugs have led indicators, and are receiving power independently, (i.e. both are not accidentally being powered simultaneously)...

Very simple circuit - Cetop 3 valve on a single manifold with PRV, feeding a reversible gear motor. Whichever solenoid is activated, the motor turns in the same direction. If I swap the hoses over, the motor does change direction, (although the valve still does not reverse the flow when the...

I think your objective is to connect both motors together to perhaps drive a twin roller feed system. If so, connect valve A to first motor A, then connect first motor B to second motor A, then connect second motor B to valve B. Output from the valve flows through the first motor, feeding the...

Looking to replace an unsuitable spool valve on an excavator. 6-bank required, with ability to control multiple banks simultaneously. Can anyone confirm which type I should be looking for? Something with a parallel circuit configuration? Or is there more to consider? My guess is that without...
