The TCG20-06-BYE-11-S105 relief valve belongs to the Relief Valves series from Vickers and protects hydraulic circuits by diverting excess pressure through a gasket-mounted body. It is identified as nominal size 06, matching manifolds cut for that cavity. An acorn nut serves as the adjuster so technicians can set spring compression without protruding levers. The unit allows pressure tuning up to 7 MPa, and its construction tolerates a maximum working pressure of 21 MPa. Flow capacity reaches 200 L/min to safeguard medium-duty pumps, while stability is maintained down to 5 L/min for low-demand operations. A low vent pressure configuration lets remote pilot lines shift the valve with minimal effort.
The valve uses an external drain so tank back pressure does not alter the relief setting. Compatibility with mineral oil or water-glycol fluids supports both standard and fire-resistant systems. Primary mounting requires four M16 × 85 mm bolts, and alternative holes accept four 5/8-11 UNC × 82.5 mm screws for imperial plates. Installation pairs with the CGM-06-10-JA-J subplate, which provides an Rc 3/4 inlet port. An Rc 1/4 gauge port offers direct pressure reading beside the valve for setup and service. The assembly weighs 6.9 kg, allowing one-person handling during cabinet integration.
