The Sun Hydraulics FTDGXRN (FTDGXRN) is a 3-way, 2-position proportional directional valve designed for precise flow control in hydraulic systems. In its default spring-biased position, it allows a metered path between ports 2 and 3 while blocking port 4. When pilot pressure is applied at port 1, it creates a metering orifice between ports 3 and 4 proportionate to the pressure at port 1, offering partial self-compensation as load pressures vary. The valve's design ensures that the nominal operating pressures for ports 1 and 6 do not exceed 500 psi (35 bar). This model can be configured into a four-way system using two three-way valves, providing flexibility in flow range selection without needing specialized spools. Additionally, external modulating logic elements like LRCXHN or LPCXHN can be used for pressure compensation in bypass or restrictive circuits. The FTDGXRN valve supports up to a maximum operating pressure of 5000 psi (350 bar) with a capacity of handling flows up to 18 gpm (70 L/min). It requires a minimum pilot pressure of 50 psi (3.5 bar) to shift the valve, with full shifting achieved at a pilot pressure of 300 psi (20 bar). The valve features Sun's floating style construction to reduce internal binding risks caused by excessive installation torque or machining variations. With minimal leakage rates of up to two cubic inches per minute at standard viscosity levels and low hysteresis values, this valve ensures efficient performance. The model weighs approximately one pound (0.45 kg) and includes Viton seals for durability under various operating conditions.

This valve is a 3-way, 2 position, proportional directional valve. In the spring biased position, a metered path is open between 2 and 3 with port 4 blocked. Pilot pressure at port 1 creates a metering orifice between 3 and 4 that is proportional to the pressure at 1. The force balance of the flow forces, spring and pilot pressure results in a degree of partial self compensation as the load pressure changes. The spring chamber is drained through port 6 and port 5 is not used.
Depending on the spool specified, ports 2, 3, and 4 are either closed or restricted during transition.
- Nominal operating pressures for port 1 and port 6 should not exceed 500 psi (35 bar).
- 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.
- 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.
