The Sun Hydraulics RPGETEN (Material Number: RPGETEN) is a fast-acting, pilot-operated, balanced piston relief cartridge valve designed to protect hydraulic components from pressure transients. This normally closed, pressure-limiting valve opens rapidly to tank port 2 when the inlet port 1 pressure reaches the valve setting, effectively throttling flow and limiting pressure rise. It features a low pressure rise versus flow rate and is known for its quick response time of approximately 2 milliseconds. The valve can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of up to 50 gpm (200 L/min). The RPGETEN model is suitable for cross-port relief circuits due to its ability to accept maximum pressure at port 2. However, it should not be used in load-holding applications because of spool leakage. The main stage orifice is protected by a robust 150-micron stainless steel screen, ensuring durability and reliability. Additionally, cartridges configured with EPDM seals are intended for systems utilizing phosphate ester fluids; exposure to petroleum-based substances could damage these seals. This model incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The valve features an adjustment screw with an internal hex size of 5/32 inches (4 mm) and requires a locknut torque of 80-90 lbf-in (9-10 Nm). Its compact design includes a valve hex size of 1-1/8 inches (28.6 mm) and an installation torque range between 45-50 lbf-ft (61-68 Nm), making it versatile for various hydraulic applications requiring precise pressure control and rapid response times.

Description

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.

Notes:

For Series 1 cartridges configured with an O control (panel mount handknob), a .75 in. (19 mm) diameter hole is required in the panel.

What are the tolerances on pressure settings for Sun's pressure control valves?	Pressure setting tolerances are listed in our Performance Data page. A link to this page can also be found in the Additional Resources tab of the applicable product page.
How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
Can I use a kick-down relief for my system relief?	Maybe not. We build in a good amount of overlap in the kick-down reliefs to prevent false tripping. This means they are not as fast as our standard pilot-operated reliefs. A direct-acting relief valve set just above the kick-down relief valve would be good insurance.
Direct acting or pilot operated - what do I use?	Direct-acting valves are used to prevent over pressure, and pilot-operated valves are used to regulate pressure. If you are unsure, use a direct-acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot-operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.
Where would I use a kick-down relief?	One graphic example is on a portable grain auger for silos. When the farmer gets caught in the auger the kick-down relief trips and allows him to escape.
