Manifold mounting
• Short stroke solenoid produces high energization shifting force.
• High force return spring due to high force solenoid maximizes
both energization and de-energization shifting forces.
• Built-in wear compensation - valve stroke is shorter than solenoid stroke.
• Four (4) bonded balanced poppets on a one-piece valve stem.
• End poppets seal first on conical seats and cushion inlet poppet, eliminating cutting.
• Exhaust seals are not under inlet pressure thus reducing friction.
• Short stroking balanced poppet allows for direct solenoid operation with high shifting forces,
minimized friction, fast response and high flow in a small package.
