The Sun Hydraulics RVEAKLN (RVEAKLN) is a ventable, pilot-operated, balanced piston relief cartridge designed for precise pressure regulation. This normally closed valve opens to tank port 2 when the inlet port 1 pressure reaches the set point, effectively throttling flow to maintain desired pressure levels. A notable feature is its vent port 3, which allows for remote control via other pilot or 2-way valves. The RVEAKLN model is characterized by its accuracy, smooth operation, low noise levels, and moderate response speed. It can handle a maximum operating pressure of up to 5000 psi (350 bar) and has a flow capacity of 30 gpm (120 L/min). The valve includes a main stage orifice protected by a 150-micron stainless steel screen and features Sun's floating style construction to reduce the risk of internal binding from installation torque or machining variations. However, it is not suitable for load-holding applications due to spool leakage considerations. The back pressure on tank port 2 directly influences the valve setting at a 1:1 ratio. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. Installation details include a valve hex size of 1-1/8 in. (28.6 mm) and an installation torque range of 45-50 lbf ft (61-68 Nm). The adjustment screw requires a 5/32 in. (4 mm) internal hex size tool with locknut torque specifications of 80-90 lbf in. (9-10 Nm). With its robust design and reliable performance characteristics, this relief cartridge is well-suited for applications requiring remote pilot relief control below its own setting while accepting maximum pressure at port 2 for cross-port relief circuits.

Ventable, pilot-operated, balanced piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
- A remote pilot relief on port 3 (vent) will control the valve below its own setting.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage.
- Main stage orifice is protected by a 150 micron stainless steel screen.
- Not suitable for use in load holding applications due to spool leakage.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
