The Sun Hydraulics RBABABV (RBABABV) is an air-controlled, pilot relief cartridge designed to remotely control the pressure setting of other pilot-operated valves. This valve is specifically engineered for applications where capacity is limited to pilot flow and should be paired with compatible pilot flow valves. Utilizing compressed air over a diaphragm instead of an adjustable spring, the pressure setting is controlled by an air signal supplied through a port in the hex end of the cartridge. The maximum allowable air pressure for this component is 150 psi (10 bar), and it can withstand back pressures at the tank port up to 1000 psi (70 bar). The hydraulic setting adjusts in direct proportion to the air setting at a ratio of 20:1, providing explosion-proof remote control capabilities. The RBABABV incorporates Sun's floating style construction, minimizing internal part binding risks due to excessive installation torque or machining variations. It features a Cavity T-3A and Series 2 capacity with a flow rate of 0.5 gpm (2 L/min) and operates under a maximum pressure of 2000 psi (140 bar). The typical response time for this valve is approximately 2 milliseconds, ensuring quick adjustments as needed. With a maximum valve leakage rate of 5 drops/minute (0.3 cc/min) at 110 SUS (24 cSt), this model ensures efficient operation with minimal fluid loss. The valve's hex size measures 1 1/8 inches (28.6 mm), and it requires an installation torque between 45 - 50 lbf ft (61 - 68 Nm). Weighing in at just .50 lb (.25 kg), it offers a lightweight solution for various hydraulic systems. A Viton seal kit is available under part number 990203006, ensuring durability under diverse operating conditions.

Description

Air-controlled, 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 valves with compatable pilot flows. They use compressed air over a diaphragm instead of an adjustable spring to control pressure setting, the air signal is supplied through a port in the hex-end of the cartridge.

Maximum air pressure should not exceed 150 psi (10 bar).
Pressure settings are insensitive to back pressure at the tank port (port 2). Back pressure should not exceed 1000 psi (70 bar).
Capable of providing explosion proof remote control of the pressure setting, the hydraulic setting is directly porportional to the air setting at a ratio of 20:1 (hydraulic:air).
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

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.
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.
