The Sun Hydraulics FTFALCV (Material Number: FTFALCV) is a 2-way, 2-position proportional throttle valve designed for precise flow control in hydraulic systems. This valve operates with ports 2 and 3 normally closed, and pilot pressure applied at port 1 opposes the spring to create a variable metering orifice between ports 2 and 3. This orifice is proportional to the pressure at port 1, allowing for partial self-compensation as load pressure changes. The dual path design incorporates double port areas for enhanced performance. For applications requiring pressure compensation, an external modulating logic element can be used; LRCXHN is recommended for bypass circuits and LPCXHN for restrictive circuits. The valve features a stroke adjustment option (L control) to limit maximum flow, enhancing accuracy in flow control applications. Ports 1 and 4 should maintain pressures under 500 psi (35 bar), as pressure at port 4 directly opposes that at port 1. The valve's construction minimizes internal part binding due to excessive torque or machining variations, ensuring reliable operation. It fits into the T-53A cavity series with a capacity of up to 50 gpm (200 L/min) and requires a minimum pilot pressure of 60 psi (4 bar) to shift the valve, with full shift achievable at a pilot pressure of 300 psi (20 bar). It can operate under maximum pressures of up to 5000 psi (350 bar), with minimal leakage rates of up to 10 in\u00b3/min at specified conditions. Installation requires specific torques, including a valve hex size of 1-1/4 inches (31.8 mm) and adjustment screw internal hex size of 5/32 inches (4 mm).

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.
