The Sun Hydraulics FXAAXAV (FXAAXAV) is a fixed orifice, pressure-compensated flow control valve designed to provide precise flow regulation for both meter-in and meter-out applications, even in scenarios with significant pressure fluctuations. This model offers a variety of flow rates, allowing it to accommodate diverse system requirements. The sharp-edged orifice design effectively minimizes flow variations due to changes in fluid viscosity, ensuring consistent performance. It can handle pressures up to 5000 psi (350 bar) at ports 1 and 2. This cartridge features a Sun floating style construction that reduces the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. It is compatible with systems using phosphate ester fluids due to its EPDM seals but should not be exposed to petroleum-based fluids, greases, or lubricants as these can damage the seals. The FXAAXAV has specific flow rate tolerances: A Flow Rate of 32 cc/min (2.0 in\u00b3/min), B Flow Rate of 40 cc/min (2.5 in\u00b3/min), D and F Flow Rates of 48 cc/min (3.0 in\u00b3/min), H and J Flow Rates of 64 cc/min (4.0 in\u00b3/min), and L Flow Rate of 72 cc/min (4.5 in\u00b3/min). The valve fits into a T8A cavity and belongs to the P series with a capacity of .5 gpm (2 L/min). The valve hex size is .78 inches (22.2 mm) with an installation torque between 25-30 lbf ft (35-40 Nm). For maintenance, Viton seal kits are available under part number 990008006. This product is ideal for applications requiring precise control over fluid flow rates across varying pressures, making it suitable for complex hydraulic systems where accuracy is crucial within specified ranges.

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.
