The Sun Hydraulics FCABXAV (Material Number: FCABXAV) is a fixed orifice, pressure-compensated flow control valve with a reverse flow check, designed for precise flow regulation in meter-in or meter-out applications. This valve is particularly useful in scenarios with wide pressure fluctuations, ensuring consistent performance. It incorporates an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1. The flow setting of this model is user-specified and preset at the factory, offering a tuneable control option with a 25% variation from the nominal factory setting. The sharp-edged orifice design minimizes variations due to viscosity changes, and the valve's construction ensures minimal binding due to excessive torque or machining variations. The FCABXAV features a T5A cavity and belongs to Series 2, capable of operating at pressures up to 5000 psi (350 bar). The valve hex size is 1-1/8 inch (28.6 mm), with installation torque ranging between 45-50 lbf ft (61-68 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size is 9/16 inch (15 mm) with a torque specification of 80-90 lbf in (9-10 Nm). Weighing approximately .50 lb (.25 kg), this model uses Viton seal kits for reliability under diverse conditions. This Sun Hydraulics flow control cartridge is physically and functionally interchangeable across similar frame sizes but may vary in extension dimensions from the mounting surface. It ensures accurate pressure-compensated control by maintaining a constant pressure differential across the valve, making it suitable for hydraulic systems requiring reliable and precise flow management.

Description

Fixed-orifice, pressure-compensated flow controls with reverse-flow check provide precise flow regulation for meter-in or meter-out applications where there may be wide pressure fluctuations. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. The flow setting is specified by the user and is set at the factory.

Customer must specify a flow rating.
Accurate pressure compensated control requires that a constant pressure differential be maintained across the valve.
The sharp-edged orifice design minimizes flow variations due to viscosity changes.
The tuneable control option provides +/- 25% variation from the nominal factory pre-set flow. Turn the adjustment clockwise to increase.
All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
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.
