The Sun Hydraulics FTHCXYV (FTHCXYV) is a 4-way, 3-position, proportional directional valve designed for precise fluid control in hydraulic systems. 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 in proportion to the pressure at port 1. Additionally, applying pilot pressure at port 6 opens the flow between ports 3 and 2. This valve features partial self-compensation due to the balance of flow forces, spring tension, and pilot pressure changes as load pressure varies. The maximum allowable pilot pressure for ports 1 and 6 is capped at 500 psi (35 bar). For enhanced performance, this valve can be paired with an external modulating logic element like the LRCXHN for bypass circuits or LPCXHN for restrictive circuits to achieve better flow control accuracy over a broader range of pressures and flows. The valve's design incorporates Sun's floating style construction to reduce the risk of internal binding caused by excessive installation torque or variations in cavity/cartridge machining. The FTHCXYV fits into a T-54A cavity and is part of Series 4 with a capacity of up to 80 gpm (320 L/min). It requires a minimum pilot pressure of 80 psi (5.5 bar) to shift the valve and can handle a maximum operating pressure of up to 5000 psi (350 bar). The valve exhibits minimal leakage at maximum conditions and has low hysteresis. Installation requires a hex size of 1-5/8 inches (41.3 mm) with an installation torque specification between 350-375 lbf-ft (475-508 Nm). A Viton seal kit is available under part number 990054006 for maintenance needs.

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.
- Maximum pilot pressure for ports 1 and 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.
