Cavagna 82-9-890-8017 Lpg Cylinder Valve Type 1 Acme CGA791

Product Description

The CAVAGNA 82-9-890-8017 is a Type 1 ACME (CGA791) LPG cylinder valve designed for DOT cylinders up to 40 pounds LPG capacity (96 pounds water capacity). It features a vapor service outlet, an integrated relief valve, a captive fixed liquid level gauge, and a built-in overfill prevention device (OPD). The valve delivers over one million BTU withdrawal capacity and is built for rapid purging and filling operations. It is installed by licensed propane service technicians and cylinder requalification facilities handling standard residential and light commercial LP cylinders.

This valve is suited for standard portable DOT propane cylinders, including common 20-pound and up to 40-pound LPG service cylinders used in residential grilling, heating, and light commercial applications. The OPD mechanism is required by NFPA 58 on cylinders of this size class, making this valve compliant for typical cylinder exchange and refill operations. Installation is performed by qualified propane handlers and cylinder service personnel.

Installation Notes

Installation must be performed by a qualified propane technician or certified cylinder requalifier in accordance with NFPA 58 and applicable DOT regulations.
