The Sun Hydraulics FKEAXCV (FKEAXCV) 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 pilot pressure at port 1 creates a metering orifice between these ports, allowing flow proportional to the pressure at port 1. The force balance of flow forces, spring, and pilot pressure provides partial self-compensation as load pressures change. Additionally, pressure at port 4 directly opposes pressure at port 1. For enhanced accuracy in flow control, the valve can be paired with an external modulating logic element such as LRCXHN for bypass circuits or LPCXHN for restrictive circuits. The valve incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. It operates within a maximum capacity of 20 gpm (80 L/min) and can withstand a maximum operating pressure of up to 5000 psi (350 bar). The valve also includes an optional tuning adjustment (L control) that allows manual variation of pilot pressure required for flow control, with an adjustment range from 50 to 300 psi (3.5 to 20 bar), and a standard setting of 100 psi (7 bar). Installation specifics include a cavity T-22A series configuration with a hex size of 1-1/8 inches and installation torque between 45-50 lbf ft (61-68 Nm). The FKEAXCV model weighs approximately .30 lb (.15 kg) and comes with Viton seal kits for durability under various conditions.

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.
