The CAVAGNA 6704901070 is a 2.5-inch female pipe thread (FPT) brass tank valve designed for underground (UG) propane tank service. Built from brass for corrosion resistance and durability, this valve features an Acme fill outlet and an integrated test port, allowing technicians to safely check pressure and fill the tank without removing the valve assembly. It is typically installed by licensed propane service technicians during tank commissioning, valve replacement, or system upgrades on buried LP tanks.
This valve is suited for underground residential and light commercial propane tank installations where a 2.5-inch FPT connection is required. The Acme fill outlet is the standard interface for propane delivery trucks, and the test port supports pressure verification during service calls. It is intended for use in below-grade tank configurations and should be installed in compliance with applicable LP-gas codes including NFPA 58.
Designed as an OEM-style replacement valve for underground propane storage tanks with a 2.5-inch FPT tank opening.
Installation must be performed by a licensed propane service technician in accordance with NFPA 58 and all applicable local codes. Ensure the tank is fully depressurized and isolated before removing or installing any valve. Use appropriate thread sealant rated for LP-gas service on all threaded connections. Do not overtighten or use tools that could damage the brass valve body or port fittings.
