Excelon® Pressure Relief Valves, protection for pneumatic tooling and compressed air systems
- In-Line or Modular Installation
- Push to Lock Adjusting Knob with Tamper Resistant Accessory
- 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.
