The Sun Hydraulics RBAPMBE2D24V (RBAPMBE2D24V) is a 2-port, pilot-stage, direct-acting relief cartridge designed as an electroproportionally controlled pressure regulating valve. Its proportional control capability allows for infinite and stepless adjustability within selected pressure ranges. When the inlet pressure at port 1 surpasses the solenoid forces, determined by an analog input signal, the poppet lifts to permit flow from port 1 to port 2. This cartridge is compatible with the Sun T8A cavity, making it suitable for use with Sun's main stage pressure control elements. The valve's operation is enhanced by varying the analog input signal to achieve smooth pressure control. The RBAPMBE2D24V features an adjustable manual override, allowing manual adjustments in case of electrical failure and enabling offsetting of the pressure range. The valve operates effectively at pressures up to 5000 psi and exhibits low leakage levels when closed, with reseat occurring at 85% of cracking pressure. The cartridge\u2019s construction includes damped features for stable operation across various conditions; however, models with an 'M' control lack a dampening orifice in the solenoid armature. This model supports EPDM seals for systems using phosphate ester fluids but warns against exposure to petroleum-based substances due to potential seal damage. It incorporates a high pilot capacity suited for larger main stage elements and utilizes Sun's floating style construction to minimize internal binding risks due to installation or machining variations. For optimal performance, it is recommended that an amplifier with current sensing and adjustable dither be used. Coils are interchangeable with other Sun solenoid-operated valves and can be mounted bi-directionally on the tube.

This 2-port, pilot-stage, direct-acting relief cartridge is an electro-proportionally controlled, pressure regulating valve. The proportional control allows for infinite, step-less adjustability within the selected pressure range. When the pressure at port 1 (inlet) is sufficient to overcome the solenoid forces, as determined by the analog input signal, the poppet lifts and allows flow from port 1 to port 2 (outlet). This pilot control cartridge utilizes the T-8A cavity so it can be used in conjunction with Sun's main stage, pressure control elements.

  • Varying the analog input signal to the proportional solenoid provides a step-less control of pressure.
  • This electro-proportional cartridge utilizes the Sun T-8A, 2-port cavity making it the ideal choice to use in conjunction with Sun's main stage cartridges. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function. Note: All 2-port pilot stage control cartridges utilize the same cavity and are physically interchangeable. Functionality is the only consideration.
  • All pressure ranges will drop to a setting of 0 with no analog input signal. The pressure ranges indicate the valve's area of acceptable performance.
  • The L control (Manual Override - Adjustable) allows one to manually adjust the valve in case of an electrical failure. The L control also allows one to offset the pressure range. For instance, if an A range valve is mechanically offset to a setting of 1500 psi (105 bar), the new maximum will be 4500 psi (310 bar).
  • The 'E' manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
  • Damped construction provides stable operation over a wide range of operating conditions. Note: Models equipped with an 'M' control do not incorporate the dampening orifice in the solenoid armature.
  • The momentary/twist override option "E" allows the operator to shift the valve by twisting the manual override clockwise 90 degrees.
  • 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.
  • Capable of operating with pressures up to 5000 psi.
  • Low leakage levels in the closed position. (Reseat occurs at 85% of cracking pressure.)
  • Coils are interchangeable with Sun's other full flow, solenoid operated valves and can be mounted on the tube in either direction.
  • For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz.
  • NOTE: There is no upper limit to the pressure setting when using the M control. The more force you exert on the manual override, the higher the resulting pressure.
  • High pilot capacity allows for operation of larger size main stage elements.
  • Note: The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.
  • 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.
