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

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

regulating valve. Increasing current to the coil will proportionally increase the pressure

setting. When the pressure at port 1 (inlet) is sufficient to overcome the solenoid force, as

determined by the analog input signal, the poppet lifts and allows flow from port 1 to port 2

(outlet).

NOTESNOTES

Please verify cartridge clearance requirements when choosing a Sun manifold. Different valve controls and coils require

different clearances.

An additional 2.00 inches (50,8 mm) beyond the valve extension is needed for coil installation and removal.

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.

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.

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

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

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.

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.
