Ensure Precise Pneumatic System Control

The Pneumatic Valve Muffler is a heavy-duty pneumatic control valve designed to reliably manage, exhaust, or vent compressed air inside professional tire changers.

Sluggish bead loosener stroke or slow clamping is often caused by micro-leaks or worn seals inside safety and exhaust valves. Replacing this valve restores full pressure to your pneumatic cylinders.

Machine Location:

This valve is located on the main air regulator filter-lubricator (FRL) unit, bead breaker cylinder, or foot pedal valve stack.
