• Balanced poppet equals consistent high shifting forces.
• Valve shifting forces are consistent and independent of pressure fluctuations.
• High solenoid and return spring forces ensure high speed and precise repeatability.
• Built-in wear compensation - valve stroke is shorter than solenoid stroke.
• Constant high flow maintained throughout the pressure range.
• Exhaust contaminants are isolated from the solenoid.
• Full flow exhaust.
• Universal porting - 6 functions in one valve.
