The TCG62-06-CVY-B-PL-T-11-S11 relief valve is produced by Vickers and belongs to the Relief Valves series. This solenoid-controlled multi-pressure relief valve regulates system pressure during hydraulic automation tasks by bleeding excess oil back to tank. The model is built in size 06, so flow paths and mounting pattern match standard 06 manifolds. It handles a maximum flow of 400 L/min, allowing it to protect medium-capacity circuits without throttling. Two pressure control stages give coarse and fine regulation so downstream components see stable pressure. The main stage can be adjusted up to 21 MPa, letting maintenance teams tune the limiting value to system requirements. External drainage through port Y prevents backpressure from influencing the set point. A high-pressure vent configuration, identified by code V, allows remote unloading when an external pilot line is energized. The valve works with either mineral oil or water-glycol, making it suitable for industrial plant or fire-resistant fluid service.
The same part number supports continuous service at a working pressure of 21 MPa, meaning normal operation can run at this level without endurance loss. A minimum stable flow of 5 L/min must be maintained so the valve spool stays centered and chatter is avoided at light loads. Installation uses a gasket mount interface, and four M16 bolts secure the body to the subplate to resist vibration. Hydraulic connections on the base are sized Rc 3/4, while the solenoid wiring terminates at a G 1/2 conduit entry to match common machine cabling. Unload capability is provided; when the pilot solenoid is energized, system flow is diverted directly to tank for energy savings during idle cycles. The assembly weighs 10.9 kg, allowing manual handling during maintenance without lifting equipment.
