The Sun Hydraulics FMDBTBN2F12V (FMDBTBN2F12V) 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 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 with the coil command current. The valve features self-compensation in this direction and can be configured with an external compensator for pressure-compensated flow control. However, flow in the 2 to 3 direction lacks proportional control. This model incorporates closed transition between positions and allows for the creation of a 4-way system using two of these valves to utilize existing flow ranges without requiring a special spool. It supports pressure compensation through an external modulating logic element and can maintain consistent flow across varying pressures and flows when paired with such elements. The valve's ports can withstand up to 5000 psi (350 bar), ensuring robust performance under high-pressure conditions. The FMDBTBN2F12V features interchangeable coils compatible with other Sun solenoid-operated valves and can be mounted on the tube in either orientation for flexibility in installation. An amplifier with current sensing and adjustable dither is recommended for optimal performance, with dither adjustable between 100-250 Hz. The manual override includes options such as a momentary-twist mechanism for temporary actuation or detent mechanisms designed for approximately 7,000 cycles of mechanical life expectancy. Additional specifications include a T-11A cavity, series 1 classification, capacity of up to 6 gpm (23 L/min), and a manual override force requirement of 5 lbs/1000 psi at Port 1. The valve weighs approximately 1.10 lb (0.50 kg) with coil included and uses Viton seal kits for both cartridge and coil assemblies.

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.
