The Sun Hydraulics FMDBMAV72499 (FMDBMAV72499) is a versatile 3-way, meter-in, electro-proportional throttle valve designed for precise flow control applications. When unenergized, the valve blocks supply at port 1 and connects 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. This valve is self-compensating in this direction and can provide pressure-compensated flow control when used with an external compensator. The valve's design allows for closed transitions between positions and can be configured as part of a 4-way system using two such valves. It supports pressure compensation through an external modulating logic element for enhanced accuracy across various flows and pressures. All ports are rated for up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. The FMDBMAV72499 features interchangeable coils with other Sun solenoid-operated valves and offers flexible installation with bidirectional mounting on the tube. Optimal performance is achieved by using an amplifier with current sensing and adjustable dither, recommended between 100-250 Hz. The manual override options include a temporary detent mechanism, with specific models providing a momentary-twist override capability for quick manual operation. Constructed using Sun's floating style design, this valve minimizes internal binding risks due to installation torque variations or machining inconsistencies. Additional specifications include a cavity size of T-11A, series 1 designation, a capacity of 6 gpm (23 L/min), and minimal leakage rates under specified conditions. The valve's manual override requires minimal force for operation and features a compact solenoid tube diameter of .75 inches (19 mm). For maintenance or replacement needs, Viton seal kits are available for both cartridge and coil components.

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.
