Normally closed, electro-proportional pressure-compensated flow control with reverse-flow check valves provide

precise flow regulation for meter-in or meter-out applications where there may be wide pressure fluctuations. They

are proportional from nearly closed up to the maximum flow. An integral high-capacity check valve provides

unrestricted flow from port 2 to port 1.

TECHNICAL FEATURES

Exceeds new NFPA test standard T2.6.1 R2014 for fatigue and burst pressure ratings.

Designed using CFD simulation for optimized geometries.

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.

Designed and tested to 5-million operational cycles at full-rated pressure.

For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 80 - 250 Hz.

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

A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.

Coils can be mounted on the tube in either direction.
