NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.

This 2-port, pilot-operated relief cartridge is an electro-proportionally controlled, normally-

closed pressure regulating valve. The valve is spring biased closed to its highest setting

(customer specified). Increasing current to the coil will proportionally decrease the pressure

setting. When the pressure at port 1 (inlet) is sufficient to overcome the spring force minus

the solenoid force, as determined by the analog input signal, the poppet lifts and allows flow

from port 1 to port 2 (outlet).

TECHNICAL FEATURESTECHNICAL FEATURES

All configurations of this valve include zinc-nickel plating as standard for 1000-hour salt fog protection.

Coil connector options offer ratings up to IP69K. See individual coil product pages for details.

This cartridge utilizes both 740 Series high-power and 747 Series hazardous location coils.

The setting represents the maximum relief pressure which the valve will default to with no command. As the command increases,

the relief setting will decrease. See performance curves for selected pressure range.

Varying the analog input signal to the proportional solenoid provides a step-less control of pressure.

For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable

between 100 - 250 Hz.

The preferred mounting configuration is horizontal or vertically with the coil down. The valve can be mounted coil up if it is installed

below reservoir oil level to prevent air accumulation in the solenoid tube. Do not actuate the valve manually or electrically when the

valve is not installed.

This valve is fully compatible with the XMD Expandable Mobile Drivers from Sun.

Coils can be mounted on the tube in either direction.

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.
