Norgren Excelon® Air Line Smooth Start/ Exhaust Dump Valves for Compressed Air Systems

Item# P72F-2AA-NNN

Norgren Excelon® Air Line Smooth Start/ Exhaust Dump Valves for Compressed Air Systems Norgren Excelon® Air Line Smooth Start/ Exhaust Dump Valves for Compressed Air Systems

The P72F Series Smooth Start/Exhaust Valves are designed for use as a single in-line unit or as part of Norgren's Excelon® modular compressed air preparation supply system. As a modular component, this smooth start /exhaust valve can quickly be attached to filters, oilers, safety lockout valves and pipe adapters. With our Quickclamp® and Quickclamp® and wall bracket accessories, a complete compressed air supply system can be assembled and mounted in minutes.

Smooth start/exhaust valves are commonly refered to as pneumatic dump valves. Smooth start valve controls the start up and shut down of pneumatic air supply by quickly controlling the air pressure to eliminate the hammering effect of sudden air pressure to pneumatic equipment. The exhaust valve blocks the inlet air supply and exhausts the downstream air when the pilot supply signal is removed.

As a modular pneumatic component, this regulator can quickly be attached to filters, oilers, smooth start / exhaust valves, safety lockout valves and pipe adapters. With our Quickclamp® and Quickclamp® and wall bracket accessories, a complete compressed air supply system can be assembled and mounted in minutes.
