3-WAY PILOT VALVE IS A VERSATILE VALVE THAT CAN<br />
BE USED WITH TRUCK/TRACTOR AND TRAILER AIR<br />
SUSPENSION SYSTEMS, MANUAL AND AUTO DUMP<br />
SYSTEMS AND AS A LIFT AXLE AIR CONTROL VALVE<br />
FEATURES AND BENEFITS<br />
fi Simple installation for normally open or normally closed operation allows one part number<br />
to be used in many applications. This flexibility reduces inventory and insures the correct<br />
parts are in stock.<br />
fi Nitrile diaphrams for all-weather operation (-40 to 200Þ F), and a beaded diaphragm lobe<br />
to eliminate air leaks found in many competitive valves.<br />
fi Robust zinc casting with integral mounting flange and di-chromate coating makes the<br />
valve highly resistant to damage and corrosion.<br />
fi Small size and optional push-in fittings make installation easy.<br />
fi Competitively priced and interchangeable with other brand valves.<br />
