The Sun Hydraulics FKIAXCV (Material Number: FKIAXCV) is a 2-way, 2-position proportional throttle valve designed for precise flow control in hydraulic systems. It features normally closed ports 2 and 3, with pilot pressure applied at port 1 to create a metering orifice between ports 2 and 3, proportional to the pressure at port 1. This design allows for partial self-compensation as load pressure changes, with pressure at port 4 directly opposing pressure at port 1. The valve can be externally modulated using logic elements like LRCXHN for bypass circuits or LPCXHN for restrictive circuits to enhance flow control accuracy over varying pressures and flows. The FKIAXCV valve incorporates Sun's floating style construction, minimizing potential binding of internal parts due to installation torque or machining variations. It operates within a capacity of up to 60 gpm (240 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The valve also features an optional tuning adjustment (L control) that allows manual variation of pilot pressure required for flow control within a range of 20-180 psi (1.4-13 bar), set standardly at 100 psi (7 bar). For optimal performance, it is crucial to maintain a constant pressure differential across the valve. Ports should not exceed pressures of 500 psi (35 bar). The valve has minimal leakage rates and features specific installation requirements such as a hex size of 1-5/8 inches (41.3 mm) and installation torque between 350-375 lbf ft (475-508 Nm). The model weighs approximately 3.30 lb (1.50 kg), and it comes with a Viton seal kit option.

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 20 - 180 psi (1,4 - 13 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.
