The Sun Hydraulics FMDBMCV224 (FMDBMCV224) is a versatile 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 while connecting port 2 to tank at port 3. When the coil is energized, it generates a closing force on the spool, creating a metering orifice in the 1 to 2 direction that adjusts proportionally to the coil command current. This valve is self-compensating in the 1 to 2 direction and can be paired with an external compensator for pressure-compensated flow control. However, flow in the 2 to 3 direction does not have proportional control. The transition between positions is closed, and using two of these valves can create a four-way system that allows selection from existing flow ranges without needing special spools. The FMDBMCV224 accommodates pressures up to 5000 psi (350 bar) across all ports and features interchangeable coils compatible with other Sun solenoid-operated valves. For optimal performance, it's recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. This model incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. It also offers manual override options with a mechanical life expectancy of approximately 7,000 cycles for models equipped with D, E, L, and T controls. The momentary-twist override option E allows manual shifting by twisting clockwise by 90 degrees. The valve's cavity is T-11A series with a capacity of up to 6 gpm (23 L/min), making it suitable for various applications requiring precise hydraulic flow control. The cartridge seal kit is available in Viton under part number 990411006.

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.
