C060T100031100A : Valvole Vented Counterbalance, 3:1, 8 GPM, 5000psi Rated, 580 to 1522psi adjustable, 1450psi Preset, T-11A

Valvole Ventilata (Vented) Ristretta Counterbalance Valve, 3:1 Pilot Ratio, Adjustable, 8 GPM, 5000psi Rated, Vented Type, 580 To 1522psi Adjustable Spring, 3045psi Pressure Setting. The Valvole America C06 Ventilata (Vented) cartridge is a counterbalance valve with a vented spring chamber. Both the relief and the pilot opening of the valve are independent from backpressure at Port 2. These valves must be used only in conjunction with directional valves with closed center spools and equipped with port relief valves. This version of the counterbalance valve will be more efficient in systems with high backpressure, or line losses between the counterbalance valve and the directional control.
