2 Direction of main-spool traveldepends upon which of the two solenoidsof the pilot valve is energized and theamount of travel is dependent upon thecurrent input to the any intermediate position of the mainspool, a force balance exists between thecontrolled, reduced pilot pressure actingon the spool end and the opposingcentering spring, plus the action of flowforces. There is no electrical feedback ofthe main-stage spool range of Valves offers effective andeconomic solutions for applications havingrepetitive load conditions throughout eachoperating cycle, mold closure/openingin plastics molding sizes 5,7 & 8 are available withintegral and BenefitsDThese global products, manufacturedto world-class quality standards, aresold and serviced throughout Valves open up expandedapplication opportunities as a costeffective alternative to feedback-typeproportional and servo flexible design approachprovides a wide variety of matchingelectronic amplifiers, valve options,and spool Section ViewsKDG5V-10 shown with EX or X (With integral pilot pressure reducer)
