The Sun Hydraulics FTCAZCN (FTCAZCN) is a 2-way, 2-position proportional throttle valve designed for precise fluid control in hydraulic systems. This valve features ports 2 and 3 that are normally closed, with pilot pressure at port 1 creating a metering orifice between these ports. The metering passage is self-compensating and utilizes a dual path design with double port areas for enhanced performance. A position switch is incorporated to confirm the valve's closed status, and it is CE approved for quality assurance. The FTCAZCN cartridge is factory sealed and not field serviceable, ensuring reliability and longevity. It requires specific installation tools like a crow's foot wrench due to the position switch design. For pressure compensation, an external modulating logic element such as LRCXHN for bypass circuits or LPCXHN for restrictive circuits can be utilized. The valve inherently provides some self-compensation, making it suitable as a flow control device across various pressures and flows. Additional features include an optional protective cover with mounting hardware (kit number: 991043), limiting pressures at ports 1 and 4 to 500 psi (35 bar), and maintaining accurate control by ensuring constant pressure differentials across the valve. The floating style construction minimizes binding issues during installation or due to machining variations. Key specifications of this model include a capacity of 15 gpm (60 L/min), maximum operating pressure of 5000 psi (350 bar), pilot volume displacement of .05 in\u00b3 (0.82 cc), and installation torque requirements of 45-50 lbf ft (61-68 Nm). The cartridge uses Viton seals (seal kit number: 990152006) for enhanced durability under various operating conditions.

Description

This valve is a 2-way, 2 position, proportional throttle. Ports 2 and 3 are normally closed. Pilot pressure at port 1 creates a metering orifice between port 2 and 3 that is proportional to the pressure at 1. The metering passage is self-compensating.

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

This valve incorporates a position switch to provide confirmation that the valve is closed.

This cartridge is supplied as a sealed, factory set unit and is not field serviceable. Any tampering will violate the product warranty.
Position switch is CE approved.
When torquing this cartridge into its cavity, a crow's foot wrench or similar will be required since the position switch precludes the use of a deep socket wrench.
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.
An optional protective cover, with mounting hardware included, may be ordered separately. See kit number: 991-043.
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.
