PYROBAN ASO VALVE

The SVH range of butterfly air shut-off valves is designed for diesel engine shutdown in the event of “over-speeding” if the engine ingests flammable gasses.

The design includes a metal to metal plate seal and high temperature bearings for today’s turbo-charged and intercooled engines. The slim butterfly design has

a low pressure drop avoiding restriction loss in engine power.
