The Sun Hydraulics RPIELEN (RPIELEN) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This normally closed, pressure-limiting valve opens quickly when the inlet port 1 reaches the set pressure, directing flow to tank port 2 and effectively throttling it to limit any further pressure increase. The valve is known for its rapid response time of approximately 2 milliseconds and exhibits low pressure rise versus flow characteristics. Its construction allows for maximum pressure acceptance at port 2, making it suitable for cross-port relief circuits; however, users should consider spool leakage in such 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 potential spool leakage. The back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. The RPIELEN features Sun's floating style construction to reduce internal binding risks caused by excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into a T-16A cavity with Series 3 capacity and can handle up to 100 gpm (380 L/min) at a maximum operating pressure of 5000 psi (350 bar). The factory sets its pressure settings at a flow rate of 4 gpm (15 L/min). Maximum valve leakage stands at approximately 4 cubic inches per minute (65 cc/min) at pressures up to 1000 psi (70 bar). Installation specifications include a valve hex size of 1-1/4 inches (31.8 mm) and an installation torque requirement of between 150 and 160 lbf-ft (203 - 217 Nm). Adjustments are made using an internal hex screw size of 5/32 inches (4 mm), with locknut torque specified between 80 and 90 lbf-in (9 -10 Nm). The model weighs approximately 1.20 lb (0.55 kg), and Viton seal kits are available under part number: 990-016-006.

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.
- 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.
