The Sun Hydraulics FXAAXJE (FXAAXJE) is a fixed orifice, pressure-compensated flow control valve designed for precise flow regulation in meter-in or meter-out applications. This model is particularly effective in scenarios with wide pressure fluctuations, offering a variety of flow rates to suit different needs. The sharp-edged orifice design minimizes flow variations due to viscosity changes, ensuring consistent performance. It can handle pressures up to 5000 psi (350 bar) at ports 1 and 2, making it suitable for high-pressure systems. The valve is compatible with systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids will damage these seals. The FXAAXJE features Sun's floating style construction, which helps prevent internal parts from binding due to excessive installation torque or machining variations in the cavity/cartridge. It fits into a T8A cavity and belongs to the P series with a capacity of .5 gpm (2 L/min). The valve has a hex size of 7/8 inches (22.2 mm) and requires an installation torque of 25-30 lbf ft (35-40 Nm). Flow rates available for this model include 2.0 in\u00b3/min (32 cc/min), 2.5 in\u00b3/min (40 cc/min), 3.0 in\u00b3/min (48 cc/min), 4.0 in\u00b3/min (64 cc/min), and up to 4.5 in\u00b3/min (72 cc/min). This product is ideal for applications requiring accurate flow control under varying conditions, providing \u00b110% accuracy, although it's set to \u00b15% during production testing for enhanced precision under specific conditions. For optimal performance, it's recommended to operate within the lower two-thirds of its range, as accuracy may decrease below .25 gpm (1 L/min) due to spool leakage and orifice conditions.

Description

Fixed-orifice, pressure-compensated flow controls provide precise flow regulation for meter-in or meter-out applications where there may be wide pressure fluctuations. A variety of flow rates are available.

The sharp-edged orifice design minimizes flow variations due to viscosity changes.
Will accept 5000 psi (350 bar) at ports 1 and 2.
Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
Flow Tolerances A Flow Rate +/- 2.0 in³/min. (+/- 32 cc/min.) B Flow Rate +/- 2.5 in³/min. (+/- 40 cc/min.) D and F Flow Rates +/- 3.0 in³/min. (+/- 48 cc/min.) H and J Flow Rates +/- 4.0 in³/min. (+/- 64 cc/min.) L Flow Rate +/- 4.5 in³/min. (+/- 72 cc/min.)
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.

Show FAQ

What happens if I block the bypass port on a priority flow control?	The valve acts as a 2 port restrictive flow control.
How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
How accurate are Sun's flow controls?	We claim +/- 10%. We set to +/- 5% in production testing to allow for differences in customers' conditions. If you want accuracy, stay in the bottom 2/3rds of the range. Our 12 gpm (45 L/min.) flow controls are quite flat at 9 gpm (34 L/min.) and dead flat below 6 gpm (23 L/min.), until you get to the bottom of the range. Below about .25 gpm (1 L/min.), spool leakage and orifice conditions start to limit accuracy.
I have a heat problem, will Sun's priority flow control help?	I am afraid not. Unless you are overflowing your current valve and correctly size ours, you are not likely to notice any improvement. Priority flow controls are not efficient devices. They are an easy way to get more than 1 source of oil from 1 pump but they can generate a lot of heat. Try to size your actuators so the pressures are similar on both the priority and the bypass circuits. If you can't do that, try to have the lower flow leg be the lower pressure. The pump pressure is determined by whichever leg is higher and if there is flow that is taking a pressure drop that is not doing work it is creating heat.
What happens if I block the control flow (priority) port?	All flow is blocked, hence the term priority. The priority flow has to be satisfied.
What is the compensating pressure of Sun's flow controls?	The spring force in our flow controls equates to about 100 psi (7 bar). This is high enough to give the valves acceptable capacity (not really) and not too high for proper circuit operation. 100 psi (7 bar) is the spring force; at the upper end of the flow control's range, the drop through the valve will be as high as 250 psi (17 bar) before it starts modulating.
What is the pressure drop through a flow control?	In a meter-in flow control circuit if the pump is set at 3000 psi and the load is 2000 psi the drop through the flow control is 1000 psi. In a meter-out circuit with the load at 2000 psi the drop through the flow control is 2000 psi.
