The Sun Hydraulics FMDBMCV2B24A (FMDBMCV2B24A) is a 3-way, meter-in, electro-proportional throttle valve designed to provide 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. When the coil is energized, it 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. This valve self-compensates in the 1 to 2 direction and can be pressure compensated with an external compensator for enhanced flow control accuracy. 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 4-way configuration allowing for existing flow range selection without requiring special spools. The FMDBMCV2B24A can handle 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 is recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. The valve incorporates Sun's floating style construction for minimizing internal part binding due to excessive torque or machining variations. Additional specifications include a T-11A cavity type, series 1 designation, capacity of up to 6 gpm (23 L/min), and maximum valve leakage of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). The manual override features a force requirement of approximately 5 lbs/1000 psi at Port 1 and has a stroke length of .10 inches (2.5 mm). The solenoid tube diameter measures .75 inches (19 mm), with a hex size of .78 inches (22.2 mm) and installation torque ranging from 30-35 lbf\u00b7ft (41-47 Nm). The model weight with coil is approximately 1.10 lb (0.50 kg).

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.
