01
Modeled telescopic cylinder as vessel_h because no dedicated cylinder symbol exists in the schematex-pid equipment catalog.
02
Used valve_control for directional and counterbalance valves with labeled ports for extend/retract.
03
Added a pressure relief valve from pump discharge to reservoir for overload protection.
04
Used hydraulic line type for all fluid power connections.
Reusable for any hydraulic circuit P&ID where counterbalance or load-holding valves need to be shown alongside pump, reservoir, and actuator.
