The Sun Hydraulics FTEAXCV (FTEAXCV) is a high-performance 2-way, 2-position proportional throttle valve designed for precise flow control in hydraulic systems. It operates by using pilot pressure at port 1 to counteract the spring force, creating a variable metering orifice between ports 2 and 3. This orifice is proportional to the pressure at port 1, allowing for partial self-compensation as load pressures fluctuate. The valve features a dual path design with double port areas at ports 2 and 3, enhancing its flow capacity. For enhanced pressure compensation, external modulating logic elements such as LRCXHN for bypass circuits or LPCXHN for restrictive circuits can be used. The FTEAXCV valve offers a degree of self-compensation and can be employed as an effective flow control device. To further improve flow control accuracy across varying flows and pressures, an external modulating logic element is recommended. The valve supports an optional L control for stroke adjustment to limit maximum flow, ensuring precise operation within specified parameters. Ports 1 and 4 are limited to a maximum pressure of 500 psi (35 bar), with accurate pressure-compensated control requiring a consistent pressure differential across the valve. This model incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into the T-53A cavity series with a capacity of up to 25 gpm (95 L/min). The minimum pilot pressure required to shift the valve is 80 psi (5.5 bar), while full shift at rated flow requires 350 psi (24 bar). The valve operates efficiently under a maximum operating pressure of up to 5000 psi (350 bar) with minimal leakage rates, making it suitable for demanding hydraulic applications where precision and reliability are critical.

Description

This valve is a 2-way, 2 position, proportional throttle. Pilot pressure at port 1 opposes the spring and creates a variable metering orifice between port 2 and 3 that is proportional to the pressure at 1. The force balance of the flow forces, spring and pilot pressure results in a degree of partial self-compensation as the load pressure changes.

Pressure at port 4 directly opposes pressure at port 1.

The valve uses a dual path design. Ports 2 and 3 incorporate a double port area.

These valves may be pressure compensated by an external, modulating, logic element. Use LR_C-XHN for a bypass circuit or LP_C-XHN for a restrictive circuit.
The valve provides a degree of self-compensation and may be used as a flow control. To increase the accuracy of flow control, an external, modulating, logic element can be used to maintain a constant flow over a wider range of flows and pressures. See performance curves for additional information.
The optional L control is a stroke adjustment that limits maximum flow.
Ports 1 and 4 should be limited to 500 psi (35 bar).
Pressure at port 4 directly opposes pressure at port 1.
Accurate pressure compensated control requires that a constant pressure differential be maintained across the valve.
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.
