The Sun Hydraulics FTECXWN (FTECXWN) is a sophisticated 4-way, 3-position proportional directional valve designed for precise fluid 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 opposing pilot pressure at port 1 against a spring, creating a variable metering orifice between ports 3 and 4 that adjusts proportionally to the pressure at port 1. Additionally, piloting at port 6 opens the flow from port 3 to port 2. This design allows for partial self-compensation as load pressures fluctuate due to the force balance among flow forces, springs, and pilot pressures. The valve can handle nominal operating pressures up to 500 psi (35 bar) at ports 1 and 6 and boasts a maximum operating pressure of up to 5000 psi (350 bar). It is suitable for use as a flow control device with some degree of self-compensation; however, for enhanced accuracy over broader flow and pressure ranges, an external modulating logic element such as LRCXHN or LPCXHN can be integrated. Featuring Sun's floating style construction, this valve minimizes internal binding risks due to excessive installation torque or machining variations. It fits within cavity T-53A and belongs to Series 3 with a capacity of up to 12 gpm (45 L/min). The minimum pilot pressure required to shift the valve is set at 80 psi (5.5 bar), while full shift at rated flow demands a pilot pressure of around 350 psi (24 bar). Its robust design ensures minimal leakage under standard conditions and incorporates Viton seal kits for reliable operation in demanding environments.

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.
