The Sun Hydraulics FTFALCN (FTFALCN) is a 2-way, 2-position proportional throttle valve designed for precise flow control in hydraulic systems. This valve features ports 2 and 3 that are normally closed, with pilot pressure at port 1 opposing the spring to create a variable metering orifice between ports 2 and 3, proportional to the pressure at port 1. The dual path design incorporates a double port area for enhanced functionality. It offers partial self-compensation as load pressure changes due to the force balance of flow forces, spring, and pilot pressure. For improved accuracy in flow control, this valve can be paired with an external modulating logic element like LRCXHN for bypass circuits or LPCXHN for restrictive circuits. The optional L control provides stroke adjustment to limit maximum flow. Ports 1 and 4 should not exceed a pressure of 500 psi (35 bar). Accurate pressure compensated control requires maintaining a constant pressure differential across the valve. The Sun floating style construction minimizes internal parts binding from excessive installation torque or cavity/cartridge machining variations. The valve fits into cavity T-53A, is part of Series 3 with a capacity of up to 50 gpm (200 L/min), and requires a minimum pilot pressure of 60 psi (4 bar) to shift. It operates at a maximum pressure of 5000 psi (350 bar) with minimal leakage rates. Installation torque should be between 150-160 lbf ft (203-217 Nm), and it features specific hex sizes for adjustments and locknuts, ensuring precise setup and maintenance in hydraulic applications.

This valve is a 2-way, 2 position, proportional throttle. Ports 2 and 3 are normally closed. Pilot pressure at port 1 opposes the spring and creates a variable metering orifice between port 2 and 3 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.
Pressure at port 4 directly opposes pressure at port 1.
The valve uses a dual path design. Ports 2 and 3 incorporate a double port area.
- 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.
- The optional L control is a stroke adjustment that limits maximum flow.
- Ports 1 and 4 should be limited to 500 psi (35 bar).
- Pressure at port 4 directly opposes pressure at port 1.
- Accurate pressure compensated control requires that a constant pressure differential be maintained across the valve.
- 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.
