The Sun Hydraulics RVGELAN (RVGELAN) is a fast-acting, ventable, pilot-operated, balanced piston relief cartridge designed for pressure regulation. This normally closed valve opens to tank port 2 when the inlet pressure at port 1 reaches the set threshold, allowing it to throttle flow and regulate pressure efficiently. It features a vent port (port 3) enabling remote control by other pilot or two-way valves. Notably, this valve exhibits low pressure rise versus flow and operates with remarkable speed, typically responding in just 2 milliseconds. The RVGELAN can handle maximum pressure at port 2, making it suitable for cross-port relief circuits; however, users should account for potential spool leakage in these applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, although the valve is not recommended for load-holding applications due to possible leakage. Back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. The design incorporates Sun\u2019s floating style construction to minimize internal binding risks from excessive installation torque or cavity machining variations. With a capacity of up to 60 gpm (240 L/min) and a maximum operating pressure of 5000 psi (350 bar), this model offers robust performance for demanding hydraulic systems. The control pilot flow ranges between 15-20 in\u00b3/min (0.25-0.33 L/min), and the maximum valve leakage is rated at 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). Installation requires specific torque settings and adjustments using internal hex sizes detailed in its specifications. Weighing approximately 1.60 lbs (0.70 kg), the RVGELAN is equipped with Viton seals and requires specific maintenance procedures as outlined by Sun Hydraulics' technical resources.
