The Sun Hydraulics RVEBLAV (Material Number: RVEBLAV) is a three-port, normally closed modulating element with relief capabilities. This versatile hydraulic component serves dual functions when paired with an external orifice. Primarily, it acts as a bypass compensator, regulating priority flow into a circuit as determined by the external orifice, while any excess input flow is redirected to the tank via port 2. Additionally, if the pressure at inlet port 1 exceeds the set valve threshold, it functions as a standard relief valve. The compensating pressure for this device across all ranges is 120 psi (8 bar). Performance curves of the RVEBLAV illustrate that its capacity and functionality are dictated by the bypass flow rather than control flow. The RVEBLAV features a T-2A cavity and belongs to Series 2, with a capacity of 20 gpm (80 L/min). It operates under a maximum pressure of 5000 psi (350 bar) and has a typical response time of 10 ms. The valve's leakage rate at 110 SUS (24 cSt) is minimal, recorded at 3 in\u00b3/min (50 cc/min) under conditions of 1000 psi (70 bar). Adjustment can be fine-tuned using either W or Y controls through its full range unless specified for a special setting. The valve installation requires torque between 45\u201350 lbf ft (61\u201368 Nm), while adjustment screw internal hex size is ^5\u204432 in. and locknut hex size is ^9\u204416 in., with locknut torque set between 80\u201390 lbf in. The model weighs approximately .70 lb (.30 kg) and utilizes Viton seal kits for optimal performance and durability.

Three-port normally closed modulating elements with relief provide two functions when combined with an external orifice. The mainstage is a bypass compensator that controls a priority flow into the circuit, determined by the external orifice. Input flow in excess of the priority flow is bypassed to tank (port 2). If the inlet (port 1) pressure rises to the valve setting, the valve operates as a normal relief valve.

  • Compensating pressure for all ranges is 120 psi (8 bar).
  • Explanation of the performance curve: The X axis is system pressure. The Y axis shows the pressure differential that the valve creates across the control orifice. The curves represent various bypass flows (pump flow minus control flow). The capacity and performance of this valve is determined by the bypass flow, control flow is not a factor.
  • W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
