The Sun Hydraulics FMDATCN724N (FMDATCN724N) is a versatile 3-way, meter-in, electro-proportional throttle valve designed for precise flow control in hydraulic circuits. In its unenergized state, the valve blocks the supply at port 1 and drains port 2 to tank at port 3. When the coil is energized, it generates a closing force on the spool, creating a metering orifice from port 1 to port 2 that is proportional to the coil command current, allowing for self-compensated flow control. The valve supports pressure-compensated flow control with an external compensator and provides limited non-proportional flow from port 2 to port 3 at approximately 1.5 gpm (6 L/min). This makes it ideal for applications requiring separate tank passages like cushion lock circuits. Two such valves can be used together in a cushion lock circuit to create a meter-in-meter-out, three-position, four-way configuration. The valve's ports can handle pressures up to 5000 psi (350 bar), and it features interchangeable coils compatible with other Sun solenoid-operated valves. It incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. For optimal performance, it's recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. The manual override options include a momentary-twist mechanism and have a mechanical life expectancy of about 7,000 cycles. The valve has a capacity of up to 9 gpm (34 L/min) with minimal leakage under specified conditions and requires specific installation torque settings for optimal operation.

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 is drained 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 and is limited in the interest of increased resolution and capacity. Flow capacity in the 2 to 3 direction is about 1.5 gpm (6 L/min). This valve is meant to be used in a circuit that has a separate passage to tank such as a cushion lock circuit. Two FMDA's in conjunction with a cushion lock circuit create a meter-in/meter-out 3 position 4-way.

  • Note: Flow in the 2 to 3 direction is limited to about 1.5 gpm (5 L/pm).
  • 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).
  • 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.
  • 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.
  • 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.
