The Sun Hydraulics FKEALCV (Material Number: FKEALCV) 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, and it operates by using pilot pressure at port 1 to create a metering orifice between ports 2 and 3. The pressure at port 4 directly opposes the pressure at port 1, providing a degree of partial self-compensation as load pressure changes. The valve can be further pressure compensated by incorporating an external modulating logic element such as LRCXHN for bypass circuits or LPCXHN for restrictive circuits, enhancing flow control accuracy over varying flows and pressures. With a cavity size of T22A and a series designation of 2, this valve offers a capacity of up to 20 gpm (80 L/min) and can withstand maximum operating pressures of up to 5000 psi (350 bar). Its design incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. The FKEALCV also includes an optional tuning adjustment (L control) that allows manual variation of pilot pressure required for flow control within an adjustment range of 50-300 psi (3.5-20 bar), with a standard setting at 100 psi (7 bar). This robust valve exhibits minimal leakage, with a maximum leakage rate of only 2 in\u00b3/min (30 cc/min) at pressures up to 1000 psi (70 bar). It requires a minimum pilot pressure of 100 psi (7 bar) to operate effectively and has been engineered with low hysteresis at \u00b12%. For optimal performance, it is recommended that ports 1 and 4 be limited to pressures not exceeding 500 psi (35 bar).

This valve is a 2-way, 2 position, proportional throttle. Ports 2 and 3 are normally closed. Pilot pressure at port 1 creates a 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.
- 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.
- Ports 1 and 4 should be limited to 500 psi (35 bar).
- Pressure at port 4 directly opposes pressure at port 1.
- An optional tuning adjustment (L control) is offered to vary the pilot pressure required to control flow. The tuning adjustment provides a means to manually increase or decrease flow at a given pilot pressure. The adjustment range is 50 - 300 psi (3,5 - 20 bar), 100 psi (7 bar) Standard Setting.
- 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.
