The Sun Hydraulics FTCALCN (FTCALCN) is a 2-way, 2-position proportional throttle valve designed for precise flow control applications. 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, allowing for partial self-compensation as load pressure changes. The valve can be externally pressure compensated using modulating logic elements such as LRCXHN for bypass circuits or LPCXHN for restrictive circuits. For enhanced flow control accuracy, an external modulating logic element can maintain constant flow across varied pressures and flows. This model includes an optional stroke adjustment feature (L control) to limit maximum flow. Ports 1 and 4 should not exceed a pressure of 500 psi (35 bar), with maximum operating pressure reaching up to 5000 psi (350 bar). The valve's construction utilizes Sun's floating style to minimize internal binding due to installation torque or machining variations. It has a capacity of up to 15 gpm (60 L/min) and requires a minimum pilot pressure of 80 psi (5.5 bar) for shifting, with full shift achieved at a pilot pressure of 300 psi (20 bar). The valve demonstrates low leakage rates and features specific torque settings for installation and adjustment components. With its robust design and precise control capabilities, the FTCALCN model is well-suited for applications requiring reliable and efficient hydraulic flow management.

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.
