TCG55-06-FEVY-PS1-H-12-S131

The TCG55-06-FEVY-PS1-H-12-S131 relief valve belongs to the Relief Valves series produced by Vickers for hydraulic automation systems that require reliable over-pressure protection and controlled venting. It is built in valve size 06 to suit mid-capacity manifolds, and it installs through gasket mounting so the body seals directly against a sub-plate without threaded pipe joints. Pressure is set with an acorn-nut square-head adjuster that permits tool-based changes while preventing accidental movement. The main stage can be adjusted up to 21 MPa, allowing the user to define a precise relief point within that range. A high vent type enables rapid pressure unloading when a remote pilot line is energized. Flow capabilities span from 5 L/min at light loads to 200 L/min at full capacity, supporting both low and high demand circuits without instability.

The maximum working pressure of 21 MPa matches the adjustable limit so the housing and internal parts tolerate continuous operation at the highest setting. An external drain route prevents back-pressure from influencing the relief spring, and the drain port uses an Rc 1/4 thread for straightforward connection to a return line. Electrical pilot control is coupled through a G 1/2 interface, simplifying wiring of proportional or on-off solenoids that shift the vent path. The unit handles mineral oil as well as water-glycol fluids, giving flexibility in plants that apply fire-resistant media. With a weight of 8.5 kg, the valve provides the mass needed to resist vibration yet remains light enough for single-person handling during maintenance.
