The compact series blow-off valves are designed for direct replacement with Bosch or Denso standard valves. In contrast to other valves with plastic diaphragms, these valves are equipped with a precisely manufactured piston that fits intake into the inside of the housing. This eliminates the risk of these valves starting to leak after a short time. Due to minimal production tolerances, no O-ring is required to seal the piston, making these blow-off valves extremely robust, low maintenance and reliable.
The Dual Port valve returns part of the air to the system. The rest is released noisily into the atmosphere.
