The Sun Hydraulics FKEALCN (FKEALCN) is a 2-way, 2-position proportional throttle valve designed for precise flow control in hydraulic systems. This valve features normally closed ports 2 and 3, with pilot pressure at port 1 creating a metering orifice between these ports proportional to the pressure at port 1. The design incorporates a force balance of flow forces, spring, and pilot pressure, allowing for partial self-compensation as load pressures vary. It offers the flexibility of pressure compensation through an external modulating logic element, such as LRCXHN for bypass circuits or LPCXHN for restrictive circuits. This enhances its capability as a flow control device over a wide range of flows and pressures. The valve's construction includes Sun's floating style to minimize internal binding due to installation torque or machining variations. With a capacity of up to 20 gpm (80 L/min) and maximum operating pressure of 5000 psi (350 bar), it suits high-demand applications. Ports 1 and 4 should be limited to pressures of 500 psi (35 bar), with port 4 directly opposing port 1's pressure. An optional tuning adjustment allows manual variation of pilot pressure from 50 to 300 psi (3.5 to 20 bar), with a standard setting at 100 psi (7 bar). The FKEALCN also features minimal leakage at high viscosities and requires a minimum pilot pressure of 100 psi (7 bar) for operation. The valve's compact design includes specific installation requirements such as a T22A cavity type, hex size specifications, and torque settings for secure fitting. It weighs approximately .30 lb (.15 kg) and comes with Viton seal kit options for enhanced durability in various environments.

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.
