The Sun Hydraulics FRCAXAN (FRCAXAN) is a bypass restrictive, fixed orifice, priority flow control designed to manage hydraulic flow efficiently. It takes input flow at port 1 and prioritizes the flow to port 3, with any excess being bypassed out of port 2 for secondary circuit use. Users can specify a factory-set flow rating within a 10% accuracy of the requested setting. This valve supports both priority and bypass flows up to the system's operating pressure, ensuring consistent priority regardless of input flow variations. The design includes a sharp-edged orifice to minimize flow variations due to viscosity changes and features an adjustable control option allowing up to 25% variation from the nominal factory preset flow through three turns of an adjust screw. The construction incorporates Sun's floating style design, reducing internal part binding risks due to installation torque or cavity machining variations. The valve fits into a T-11A cavity and belongs to series 1, with a capacity of 6 gpm (23 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). It accommodates a maximum input flow of 15 gpm (60 L/min). Installation requires a valve hex size of 7/8 in. (22.2 mm) with torque specifications ranging from 30-35 lbf ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut has a hex size of 9/16 in. (15 mm) with torque requirements between 80-90 lbf in (9-10 Nm). Weighing just .30 lb (.15 kg), this model is compact yet robust for various hydraulic applications requiring precise flow control and management.

Description

Bypass/restrictive, fixed-orifice, priority flow controls take an input flow at port 1 and use it to satisfy the priority flow at port 3. If the input flow exceeds the priority flow requirement, the excess is bypassed out port 2. The bypass flow may be used in a secondary circuit.

Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.
Both priority and bypass flow are usable up to the system operating pressure.
Priority remains relatively constant regardless of variation in input flow.
Bypass flow is not available until priority flow requirements are satisfied.
Pressure at the bypass port (port 2) may exceed pressure at the priority port (port 3).
The sharp-edged orifice design minimizes flow variations due to viscosity changes.
A tuneable adjustment control option provides up to +/- 25% variation from the nominal factory pre-set flow. Adjustment is done with +/- 3 turns of the adjust screw. Screw in (CW) to increase flow.
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.
