The Sun Hydraulics FPHKXEV (FPHKXEV) is a pilot-operated, normally closed electroproportional throttle valve featuring a reverse free flow check. When the coil is energized, it creates an opening force on the pilot stage, allowing the main stage poppet to open proportionally, facilitating metered flow from port 1 to port 2 and reverse free flow from port 2 to port 1. This valve operates efficiently under pressures up to 5000 psi. It is compatible with interchangeable coils from Sun's other full-flow solenoid-operated valves, which can be mounted on the tube in either direction for flexible installation. The FPHKXEV model includes several manual override options, such as a momentary-twist override that allows operation by twisting the manual override clockwise by 90 degrees. It incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge setups. For optimal performance, an amplifier with current sensing and adjustable dither\u2014recommended between 100-250 Hz\u2014should be used. This cartridge valve fits into a T16A cavity and belongs to Series 3 with a capacity of 60 gpm (240 L/min). The maximum valve leakage at 110 SUS (24 cSt) is minimal at only 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The manual override requires a force of approximately 5 lbs/1000 psi (33 N/100 bar) at Port 1, and it has a manual override stroke of .06 inches (1.50 mm). The solenoid tube diameter measures .75 inches (19 mm), while the valve hex size is set at 1\u00bc inches (31.8 mm), requiring an installation torque between 150-160 lbf ft (203-217 Nm). With its robust design and versatile application capabilities, this model weighs about 1.50 lbs without coil and approximately 2.00 lbs with coil installed. The seal kit for this cartridge is available in Viton under the part number: Viton:990016006.

Description

This valve is a pilot operated, normally closed, electro-proportional throttle with reverse free flow check. Energizing the coil generates an opening force on the pilot stage which vents the main stage poppet to open proportionally. Metered flow is from port 1 to port 2 with reverse free flow from port 2 to port 1.

Capable of operating with pressures up to 5000 psi.
Coils are interchangeable with Sun's other full flow, solenoid-operated valves and can be mounted on the tube in either direction.
This cartridge has several manual override choices, including no manual override. See Option Configuration.
For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz.
The momentary/twist override option "E" allows the operator to shift the valve by twisting the manual override clockwise 90 degrees.
Depending on circuit requirements, a reverse free flow check bypassing the compensator may be needed when using the FPHK with an external compensator.
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.
