Helps Protect Air Operated Equipment from Over Pressure by Retarding Excessive Pressure Build Up
The V72G series has been discontinued. Please contact our Flow Engineering department.
The V72G Series Air Pressure Relief Valves
are designed for use as a single in-line unit or as part of Norgren's
Excelon® modular compressed air preparation supply
system. A pressure relief valve is uses to protect pneumatic
equipment from over pressure by retarding excessive pressure build up.
As a modular component, this pressure relief valve can quickly
be attached to air filters, lubricators, 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.
