The Sun Hydraulics DRBRLEV (Material Number: DRBRLEV) is a direct-acting, 3-way directional cartridge valve designed for moderate flow circuits. This versatile component can function independently or in conjunction with larger pilot-operated directional cartridges or logic cartridges. The valve operates by shifting when the pressure differential between port 1 and port 4 exceeds its setting, with a maximum allowable setting of 800 psi (55 bar). It is essential to limit the maximum pressure at port 3 to 3000 psi (210 bar) due to fatigue strength constraints, not hydraulic operating limits. The flow path between port 2 and port 3 is bidirectional, which enhances its application flexibility. Characterized by low internal leakage and minimal pilot flow consumption due to its direct-acting design, the DRBRLEV valve is not bistable but can modulate between two positions. It features Sun's floating style construction, reducing the risk of internal component binding due to excessive installation torque or cavity/cartridge machining variations. With a cavity size of T-21A and a series designation of 1, this valve has a capacity of handling up to 7 gpm (28 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The valve's maximum leakage at an oil viscosity of 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min). Installation requires specific torques: the valve hex size is 7/8 inch (22.2 mm), with an installation torque range of 30\u201335 lbf\u00b7ft (41\u201347 Nm), while the locknut hex size is 9/16 inch (15 mm) with a torque requirement of 80\u201390 lbf\u00b7in (9\u201310 Nm). For maintenance, a Viton seal kit with part number 990021006 is available.

Direct-acting, 3-way directional cartridges (3 to 4 open, 2 blocked) are switching devices typically used in moderate flow circuits. They can be used by themselves or to actuate larger pilot operated directional cartridges or logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the setting.
- Note: 800 psi (55 bar) is the highest setting possible with this valve.
- Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.
- The flow path between port 2 and port 3 is bidirectional.
- Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption.
- This valve is not bistable; it is capable of modulating between the two positions shown.
- 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.
