The Sun Hydraulics FTDCXYN (FTDCXYN) is a 4-way, 3-position proportional directional valve designed for precise flow control applications. In its center position, work ports 2 and 4 are drained to port 5, while port 3 remains closed. The valve operates by using pilot pressure at port 1 to counteract the spring force, creating a variable metering orifice between ports 3 and 4 proportional to the pressure at port 1. Conversely, piloting at port 6 opens the flow from port 3 to port 2. The force balance involving flow forces, spring tension, and pilot pressure allows for partial self-compensation as load pressures vary. This model features a nominal operating pressure limit of 500 psi (35 bar) for both ports 1 and 6 and can be externally pressure compensated using modulating logic elements such as LRCXHN for bypass circuits or LPCXHN for restrictive circuits to enhance flow control accuracy across varying conditions. The valve is constructed with Sun's floating style design to minimize internal binding due to installation torque or machining variations in cavity/cartridge interfaces. It fits a T-52A cavity from Series 2 with a capacity of up to 18 gpm (70 L/min). For optimal operation, it requires a minimum pilot pressure of 80 psi (5.5 bar) to shift and up to 300 psi (20 bar) for full shift at rated flow. It can withstand maximum operating pressures up to 5000 psi (350 bar), with leakage rates restricted to a maximum of approximately 30 cc/min at specified fluid viscosity levels. The valve has minimal hysteresis of \u00b12% and requires an installation torque between 45-50 lbf ft (61-68 Nm). It is compatible with Viton seal kits identified as model number: Viton:990052006.

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.
