The PA model comes with a integrated pneumatic cylinder that operates at a minimum 60 PSI air pressure. The PA valve is designed to stay closed even in the event of engine backfire. This valve can be utilized in temperature extremes ranging from -40 deg C to +204 deg C.
The PA models have a fail safe option available for those who want to be able to close the valve in the event of power or air loss. A cable can be attached to the back of the plunger for emergency operation.
Other configurations are available upon request, such as automated fail safe in the event of air pressure loss.
