The Sun Hydraulics FTDGXCN (FTDGXCN) is a 3-way, 2-position proportional directional valve designed for precise flow control in hydraulic systems. In its spring-biased position, it allows a metered flow between ports 2 and 3 while port 4 remains blocked. When pilot pressure is applied at port 1, the valve creates a metering orifice between ports 3 and 4, with the flow being proportional to the pressure at port 1. This configuration offers partial self-compensation as load pressures fluctuate. The spring chamber is drained through port 6, and port 5 is not utilized in this setup. Depending on the spool configuration, ports 2, 3, and 4 may be closed or restricted during transitions. The valve operates at nominal pressures up to 500 psi (35 bar) for ports 1 and 6 and can handle a maximum operating pressure of up to 5000 psi (350 bar). It has a capacity of handling flows up to 18 gpm (70 L/min). To achieve full shift at rated flow, a pilot pressure of approximately 300 psi (20 bar) is required, with a minimum pilot pressure of about 50 psi (3.5 bar) necessary to initiate valve shifting. This valve features Sun\u2019s floating style construction that reduces the risk of internal parts binding due to installation torque or machining variations. It can be used as part of a flow control system and may be combined with external modulating logic elements like LRCXHN for bypass circuits or LPCXHN for restrictive circuits to enhance accuracy over varying flow rates and pressures. The FTDGXCN model includes Viton seals as part of its construction for durability in demanding environments.

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.
