• 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.

1. Short stroke solenoid produces high
energization shifting force.
2. High force return spring due to high force
solenoid maximizes both energization and
de-energization shifting forces.
3. Built-in wear compensation – valve stroke is
shorter than solenoid stroke.
4. Four bonded balanced poppets on a one-
piece valve stem.
5. End poppets seal first on conical seats and
cushion inlet poppet, eliminating cutting.
6. Exhaust seals are not under inlet pressure thus
reducing friction.
7. Integral non-rising flow controls available on
inline models.
8. Short stroking balanced poppet allows for
direct solenoid operation with high shifting
forces, minimized friction, fast response and
high flow in a small package.
