The Sun Hydraulics FTFAZCV (Material Number: FTFAZCV) is a 2-way, 2-position proportional throttle valve designed for precise flow control in hydraulic systems. This valve features ports 2 and 3 that are normally closed, with pilot pressure applied at port 1 to create a metering orifice between ports 2 and 3, proportional to the pressure at port 1. Its dual-path design incorporates a double port area for enhanced functionality. The FTFAZCV is self-compensating, providing consistent performance without manual adjustments. It includes a position switch for confirmation of valve closure, which is CE approved, ensuring reliability in operation. This cartridge valve is supplied as a sealed unit from the factory and is not field serviceable; tampering voids the warranty. Installation requires specific tools such as a crow's foot wrench due to the position switch configuration. The valve can be pressure compensated using external modulating logic elements like LRCXHN for bypass circuits or LPCXHN for restrictive circuits, enhancing flow control accuracy across varying pressures and flows. With a maximum operating pressure of 5000 psi (350 bar) and capable of handling up to 50 gpm (200 L/min), this valve suits high-pressure applications requiring precise flow management. It operates within specified torque limits to prevent internal binding due to installation variations. An optional protective cover can be ordered separately using kit number: 991043, providing additional protection during operation. The FTFAZCV's design incorporates Sun's floating style construction, minimizing potential issues from excessive torque or machining variations during installation, ensuring long-term operational stability and efficiency in demanding hydraulic applications.

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.
