The Sun Hydraulics FXAGXBV (FXAGXBV) is a fixed orifice, pressure-compensated flow control valve designed for precise flow regulation in both meter-in and meter-out applications, especially where there are significant pressure fluctuations. This product features a sharp-edged orifice design that minimizes variations in flow due to changes in viscosity. It offers a variety of flow rates, including 2.0 in/min (32 cc/min), 2.5 in/min (40 cc/min), 3.0 in/min (48 cc/min), 4.0 in/min (64 cc/min), and 4.5 in/min (72 cc/min). The valve is capable of handling a maximum operating pressure of up to 5000 psi (350 bar) at ports 1 and 2. The FXAGXBV incorporates Sun's floating style construction, which reduces the risk of internal parts binding due to excessive installation torque or machining variations within the cavity/cartridge. This valve is designed for flush mounting, providing a compact footprint that can be easily integrated with the surface of the manifold. The product fits within a T8A cavity and belongs to Series P with a capacity of .5 gpm (2 L/min). Installation requires an internal hex size of 5/16 inch (8 mm) and an installation torque range between 25-30 lbf ft (35-40 Nm). The valve also utilizes Viton seals with part number 990008006. Sun Hydraulics' flow controls claim an accuracy of \u00b110%, although they are set to \u00b15% during production testing to accommodate varying customer conditions. For optimal accuracy, it is recommended to operate within the lower two-thirds of the specified range. This flow control valve is not designed to address heat problems unless properly sized for specific applications; otherwise, it may contribute to heat generation due to inefficiencies typical of priority flow controls.

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.
Flush mount valves provide a small footprint. They can easily be mounted flush with the surface of the manifold.
Will accept 5000 psi (350 bar) at ports 1 and 2.
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.
