The Sun Hydraulics RPGEJAN (Material Number: RPGEJAN) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This normally closed valve limits pressure rise by opening to tank port 2 when the inlet pressure at port 1 reaches the set threshold. It features a low pressure rise versus flow and operates with exceptional speed, although this comes at the expense of smoothness. The cartridge is suitable for use in cross-port relief circuits, accepting maximum pressure at port 2; however, spool leakage should be considered in such applications. It incorporates a 150-micron stainless steel screen protecting the main stage orifice and uses Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. This cartridge is not recommended for load-holding applications due to potential spool leakage. Additionally, back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. Cartridges with EPDM seals are compatible with phosphate ester fluids but can be damaged by petroleum-based fluids. The valve fits into a T-3A cavity and is part of Series 2, offering a capacity of up to 50 gpm (200 L/min). It operates under a maximum pressure of 5000 psi (350 bar) with typical response times around 2 ms and minimal leakage rates. Adjustment options include five clockwise turns to increase settings, with specific hex sizes for valve adjustment and locknut torque requirements provided for precise installation and maintenance. The model weighs approximately .50 lb (0.25 kg), and Viton seal kits are available under part number 990203006 for maintenance needs.

Fast-acting, pilot-operated, balanced piston relief cartridges are normally closed, pressure-limiting valves used to protect hydraulics components from pressure transients. Fast opening and closing is gained at the expense of smoothness. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These valves have low pressure rise vs. flow and are very fast.
- All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
- 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.
