The Sun Hydraulics FDBACAN (Material Number: FDBACAN) is a fully adjustable, pressure-compensated flow control valve designed to provide precise flow regulation for both meter-in and meter-out applications. It is particularly effective in environments with wide pressure fluctuations. The valve features an integral high-capacity check valve that allows unrestricted flow from port 2 to port 1, making it versatile for various hydraulic systems. The valve's design includes a balanced adjustment mechanism that facilitates easy adjustments even at high pressures, and its sharp-edged orifice minimizes flow variations due to viscosity changes. This model offers minimal leakage of 0.1 gpm when the adjustment mechanism is turned to the shutoff position. The FDBACAN model fits into a T-13A cavity and belongs to Series 1 with a capacity of up to 6 gpm (23 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). It features an adjustment range of up to 5.5 counterclockwise turns from fully closed to fully open. The valve's hex size is .78 inches (22.2 mm), requiring an installation torque of 30\u201335 lbf ft (41\u201347 Nm). The internal hex size for the adjustment screw is .156 inches (4 mm), while the locknut hex size is .562 inches (15 mm), with a locknut torque requirement of 80\u201390 lbf in (9\u201310 Nm). This model weighs approximately .40 lb (.20 kg) and can be equipped with Viton seals for compatibility with specific fluid types, such as phosphate ester fluids.

Description

Fully adjustable, 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. They are infinitely adjustable from nearly closed up to the maximum flow. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1.

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.
A balanced adjustment mechanism allows for easy adjustment even at high pressures.
The sharp-edged orifice design minimizes flow variations due to viscosity changes.
Minimum leakage is .1 gpm (0,4 L/min) when the adjustment mechanism is turned to the shut-off position.
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.

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.
