VALVE ACCESSORIES<br />
The dual exhaust and balanced design of the <strong>Alkon</strong> valve allows for the use of<br />
inexpensive exhaust metering valves. When screwed into the exhaust ports, they<br />
independently control the actuator speed in either or both directions.<br />
Metering valves have aluminum bodies and steel adjusting screws.<br />
Mufflers are used to silence the noise caused by exhausting air. Both standard<br />
mufflers and speed control mufflers are made of brass and sintered bronze.<br />
