TCG-06-CV-40-S4

The TCG-06-CV-40-S4 valve belongs to the Relief Valves series and is manufactured by Vickers. It is installed in hydraulic automation loops to open when system pressure reaches a preset level and discharge flow to tank, protecting pumps and actuators. The unit carries the size 06 designation, matching subplate and line-mounting patterns common in medium-capacity circuits. A rated flow capability of 200 L/min lets the element handle large return volumes without excessive pressure rise. The assembly withstands a maximum working pressure of 21 MPa (3045 psi), ensuring compatibility with high-pressure industrial machinery. Internal drain routing returns pilot flow directly to the outlet port, which simplifies installation by eliminating an external drain line. A high vent configuration (code V) provides a dedicated path for rapid pressure decay when the pilot signal is removed. The cartridge performs the pressure relief function required for steady system operation.

Pressure setting can be adjusted up to 14 MPa, allowing the user to calibrate the valve precisely to circuit requirements while keeping margin below the housing limit noted earlier. The TCG-06-CV-40-S4 weighs 6.9 kg, so panel or manifold supports must account for this load during service. Acceptable working media include mineral oil or water-glycol blends, ensuring compatibility with common hydraulic fluids and fire-resistant solutions. These characteristics support deployment in presses, test stands, and general power units where controlled pressure limiting is essential. The internal construction maintains stable performance across the full flow range and prevents chatter when approaching relief pressure. Together these specifications define a compact device that manages energy dissipation, maintains preset line pressure, and integrates smoothly into existing Vickers hydraulic architectures.
