All ports are equally pressure resistant, due to the internal pressure compensation. Valves featuring a spring return will return automatically into their idle position when not activated. The detented version will achieve its idle or working position after a brief impulse at the opposing solenoid. o Version for pipe connection o Version for manifold mounting o Version as double valve (distribution valve) HAWE Hydraulik SE STREITFELDSTR. 25 • 81673 MÜNCHEN © 1999 by HAWE Hydraulik Seated valves BVG(P) 1 September 20
