The Sun Hydraulics FMDBEAN2B12V (FMDBEAN2B12V) is a 3-way, meter-in, electro-proportional throttle valve designed for precise flow control in hydraulic systems. In its unenergized state, the valve blocks the supply at port 1, connecting port 2 to the tank at port 3. When energized, the coil generates a closing force on the spool, creating a metering orifice from port 1 to port 2 that is proportional to the coil command current. This valve self-compensates in the 1 to 2 direction and can provide pressure-compensated flow control with an external compensator. Flow from port 2 to port 3 is not proportional. The transition between positions is closed, and using two of these valves can create a four-way system allowing for existing flow ranges without needing special spools. The valve can be pressure compensated using an external modulating logic element such as LRCXHN for a bypass circuit or LPCXHN for a restrictive circuit. It offers self-compensation and can function as a flow control device; however, accuracy can be enhanced with an external logic element. The FMDBEAN2B12V accommodates up to 5000 psi (350 bar) across all ports and features interchangeable coils compatible with other Sun solenoid-operated valves. For optimal performance, an amplifier with current sensing and adjustable dither (100-250 Hz) is recommended. Models equipped with D or L controls include a detent mechanism for temporary manual actuation with approximately 7,000 cycles of mechanical life expectancy. This valve incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. It fits into cavity T-11A, has a capacity of 6 gpm (23 L/min), and weighs approximately 1.10 lb (0.50 kg) with coil included.

This valve is a 3-way, meter-in, electro-proportional throttle. The flow path, unenergized, has the supply blocked at port 1 and port 2 connected to tank at port 3. Energizing the coil generates a closing force on the spool, creating a metering orifice in the 1 to 2 direction that is proportional to the coil command current. The valve self-compensates in the 1 to 2 direction and with the addition of an external compensator will provide pressure compensated flow control. Flow in the 2 to 3 direction is not proportional.
- The transition between positions is closed.
- Using 2 3-ways to create a 4-way allows one to choose existing flow ranges instead of cutting a special spool.
- These valves may be pressure compensated by an external, modulating, logic element. Use LR_C-XHN for a bypass circuit or LP_C-XHN for a restrictive circuit.
- The valve provides a degree of self-compensation and may be used as a flow control. To increase the accuracy of flow control, an external, modulating, logic element can be used to maintain a constant flow over a wider range of flows and pressures. See performance curves for additional information.
- All ports will accept 5000 psi (350 bar).
- 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.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, E, L and T manual control assemblies have a mechanical life expectancy of approximately 7,000 cycles.
- The momentary/twist override option "E" allows the operator to shift the valve by twisting the manual override clockwise 90 degrees.
- 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.
