The Sun Hydraulics RBATFCV (Material Number: RBATFCV) is a direct-acting, pilot relief cartridge valve designed for precise pressure control in hydraulic systems. This valve is primarily used to remotely control the pressure setting of other pilot-operated valves and is ideal for load-holding applications. It features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in demanding environments. The RBATFCV 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's capacity is 0.25 gpm (1 L/min), with a maximum operating pressure of 5000 psi (350 bar). It offers a typical response time of 2 milliseconds and has minimal leakage at maximum valve leakage of 5 drops/minute (0.3 cc/min) at 110 SUS (24 cSt). The adjustment mechanism allows for up to five clockwise turns to increase the setting, providing flexibility and precision in pressure adjustments. Installation requirements include a valve hex size of 7/8 inch (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size is 9/16 inch (15 mm), with a locknut torque specification of 80-90 lbf in (9-10 Nm). The model weighs approximately 0.30 lb (0.15 kg) and utilizes Viton seals for optimal performance under various conditions. This cartridge valve is suitable for applications where back pressure on the tank port is directly additive to the valve setting at a 1:1 ratio, making it an efficient choice for systems requiring stable and robust pressure regulation.

Description

Direct-acting, pilot relief cartridges are used to remotely control the pressure setting of other pilot-operated valves. Because capacity is limited to pilot flow, these valves should be used with other higher flow valves.

Main stage orifice is protected by a 150 micron stainless steel screen.
Suitable for use in load holding applications.
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.

Show FAQ

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.
