The Sun Hydraulics FTDCXWN (FTDCXWN) is a 4-way, 3-position proportional directional valve designed for precise flow control in hydraulic systems. This valve features work ports 2 and 4 that are drained to port 5 in the center position, while port 3 remains closed. It operates by utilizing pilot pressure at port 1 to oppose the spring, creating a variable metering orifice between ports 3 and 4 proportional to the pressure at port 1. Piloting at port 6 opens the flow between ports 3 and 2, allowing for a degree of partial self-compensation as load pressures fluctuate. The valve is characterized by its floating style construction, minimizing potential binding from installation torque or machining variations. The FTDCXWN model is capable of handling a maximum operating pressure of up to 5000 psi (350 bar), with nominal operating pressures for ports 1 and 6 not exceeding 500 psi (35 bar). It has a capacity of managing flow rates up to 18 gpm (70 L/min) and requires a minimum pilot pressure of 80 psi (5.5 bar) to shift the valve, with full shift at rated flow needing up to 300 psi (20 bar). The valve's design incorporates low hysteresis and moderate leakage rates, ensuring efficient operation within specified parameters. For enhanced accuracy in flow control applications, users may integrate an external modulating logic element such as LRCXHN for bypass circuits or LPCXHN for restrictive circuits. This configuration allows for maintaining consistent flow across varying pressures. The FTDCXWN model is also equipped with Viton seals for reliable performance in demanding environments and comes with comprehensive installation guidelines to ensure optimal functionality.

This valve is a 4-way, 3 position, proportional directional valve. Work ports 2 and 4 are drained to 5 in the center position and port 3 is closed. Pilot pressure at port 1 opposes the spring and creates a variable metering orifice between ports 3 and 4 that is proportional to the pressure at 1. Piloting 6 opens 3 to 2. The force balance of the flow forces, spring and pilot pressure results in a degree of partial self compensation as the load pressure changes.
Pressure at ports 1 and 6 directly oppose each other.
- Nominal operating pressures for port 1 and port 6 should not exceed 500 psi (35 bar).
- 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.
- Pressure at ports 1 and 6 directly oppose each other.
- 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.
