The Sun Hydraulics FMDBEBV71299 (FMDBEBV71299) is a sophisticated 3-way, meter-in, electro-proportional throttle valve designed for precise flow control in hydraulic systems. In its unenergized state, the valve blocks supply at port 1 while connecting port 2 to the tank at port 3. Upon energizing the coil, a closing force is applied to the spool, creating a metering orifice in the 1 to 2 direction proportional to the coil command current. The valve self-compensates in this direction and can provide pressure-compensated flow control when paired with an external compensator. Notably, flow in the 2 to 3 direction is not proportional. This model features closed transition between positions and allows users to create a 4-way configuration by using two 3-way valves, offering flexibility in choosing existing flow ranges without needing custom spools. The valve is compatible with external modulating logic elements for enhanced pressure compensation and accuracy over varying flows and pressures. All ports can handle up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. The FMDBEBV71299 incorporates interchangeable coils with Sun's other solenoid-operated valves for versatile installation options. For optimal performance, it is recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. The valve also includes manual override options with mechanical life expectancy of approximately 7,000 cycles. Designed with Sun's floating style construction, this valve minimizes potential binding issues due to installation torque or machining variations. It fits into a T-11A cavity and offers a capacity of up to 6 gpm (23 L/min). The model weighs approximately 1.10 lb (0.50 kg) when equipped with a coil and requires specific Viton seal kits for maintenance purposes.

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.
