The Sun Hydraulics RPIECAN (Material Number: RPIECAN) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. These valves are normally closed and pressure-limiting, opening quickly when the inlet port pressure reaches the valve setting to throttle flow and limit further pressure rise. The design prioritizes rapid response over smoothness, making it suitable for applications where swift opening and closing are critical. This model features a low-pressure rise versus flow and can handle a maximum operating pressure of 5000 psi (350 bar) with a typical response time of 2 milliseconds. It has a capacity of 100 gpm (380 L/min) and is equipped with a main stage orifice protected by a 150-micron stainless steel screen. The RPIECAN is physically and functionally interchangeable with other 2-port relief cartridges in the same frame size, ensuring versatility in various setups. It can accept maximum pressure at port 2, making it suitable for cross port relief circuits, though users should consider spool leakage in such configurations. The valve incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. It's not recommended for load-holding applications due to spool leakage, and back pressure on the tank port directly affects the valve setting at a 1:1 ratio. For adjustment, it requires up to five clockwise turns to increase the setting, with specific torque values provided for installation and locknut adjustments. Weighing 1.20 lb (0.55 kg), this cartridge also comes with an optional Viton seal kit for enhanced durability in demanding environments.

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.
