Hydraulic Schematic Symbols
Hydraulic Schematic Symbols
(OP)
I am working on a hydraulic system for a boom slew actuator and am unsure what the attached symbols represent. The first symbol was in a hydraulic line between the actuator cylinders and the directional valve. The other is a solenoid operated directional valve that has extra geometry which I do not recognize. Any help is appreciated!

The bottom one is a manual override for the DCV.

Thank you for the response. I suspected the directional valve geometry might represent a manual override.. glad that has been confirmed. Attached is a larger schematic showing the 1st symbol in context hopefully. The only other boom slew schematic I have seen with blocks between the cylinders and the directional valve also employed a flow control followed by a shut off valve, plugged tee for testing, and plugged bleed valve.

They don't look like they do anything anyway...could they have been left on the drawing in error?
If you delete them the drawing will make more sense!!!

I would just delete the other symbols, they don't mean anything and just look wrong.
