Benefits for your build

PNEUMATIC ACTUATION

The pressure type must match the existing or planned supply.

CHECK THE REST POSITION

The rest position describes the state with no control pressure applied.

Actuation	Positive pressure
Rest position without control pressure	Closed
Nominal inch designation	2.375 inch
SKU	AR4221

Applications

For custom exhaust layouts where valve position and the available exhaust path are matched to the engine in every operating state. Check the actual vehicle?s noise and approval requirements before use. Road approval is not claimed.

Supply & compatibility

The offered configuration is decisive. A complete accessory list is not documented; confirm required controls, hoses, wiring and mounting parts before ordering.

Installation & notes

Install without preload in a suitable straight pipe section. Protect the actuator from welding heat. Route control hoses away from heat and use only the pressure type required by the actuator. Check both end positions, return action, clearance and sealing.

Frequently asked question

Can the valve fully block the only exhaust route?

Complete closure of the only exhaust route must not be planned as a normal operating state. Bypass routing, valve control and exhaust backpressure require professional design for the engine.
