The Sun Hydraulics RPEETNV (RPEETNV) 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 pressure reaches the valve setting, diverting flow to the tank port to limit pressure rise. It features low pressure rise versus flow and rapid response times, making it suitable for applications requiring quick actuation. The valve can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 25 gpm (95 L/min). It is particularly useful in cross-port relief circuits due to its ability to accept maximum pressure at port 2; however, users should consider spool leakage in such applications. The main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability. This model is not recommended for load-holding applications due to potential spool leakage. Additionally, back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. The RPEETNV incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. It is adjustable through its full range using W or Y controls unless a special setting is specified as the maximum setting. The valve has an installation torque of 30-35 lbf ft (41-47 Nm), with adjustment screw and locknut hex sizes of 5/32 in. (4 mm) and 9/16 in. (15 mm), respectively. This relief cartridge weighs .30 lb (.15 kg) and comes with a Viton seal kit (990010006). Its compact design allows for easy integration into existing systems while maintaining high performance standards in demanding hydraulic environments.

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.

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.
All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
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.
