The Sun Hydraulics FCEBKBN (FCEBKBN) is a fixed orifice, pressure-compensated flow control valve designed for precision flow regulation in both meter-in and meter-out applications. It is adept at handling scenarios with significant pressure fluctuations. This model features an integral high-capacity check valve that allows for unrestricted flow from port 2 to port 1, ensuring efficient operation. The factory sets the flow rate based on customer specifications, with a tolerance of \u00b110% from the requested setting. The sharp-edged orifice design of this valve minimizes variations in flow due to changes in fluid viscosity, making it highly reliable in various conditions. All two-port flow control cartridges are interchangeable within their frame size, providing flexibility in installation and maintenance. The FCEBKBN model includes a tuneable control option allowing for a \u00b122% variation from the nominal factory preset flow rate by adjusting clockwise to increase the flow. Constructed with corrosion-resistant materials, this cartridge is suitable for use in corrosive environments, with options for external stainless steel or zinc-nickel plated components. The Sun floating style construction minimizes internal binding due to excessive torque or machining variations during installation. This model fits into a T-16A cavity and belongs to Series 3, offering a capacity of up to 25 gpm (95 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Installation requires careful attention to torque specifications: valve hex size is 1-1/4 inches (31.8 mm), with an installation torque of 150-160 lbf ft (203-217 Nm). The adjustment screw features an internal hex size of 5/32 inches (4 mm), while the locknut has a hex size of 9/16 inches (15 mm) and requires a torque of 80-90 lbf in (9-10 Nm). The model weighs approximately 1 lb (0.45 kg) and utilizes Viton seals under part number 990016006 for optimal performance.

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. Factory set flow ratings are within +/- 10% of the requested setting.
The sharp-edged orifice design minimizes flow variations due to viscosity changes.
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.
The tuneable control option provides +/- 22% variation from the nominal factory pre-set flow. Turn the adjustment clockwise to increase.
Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
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.
