Apollo 6GA-11A-B1-LF Gate Valve 4 in Flanged 125 Lb

Product Description

The Apollo 6GA-11A-B1-LF is a lead-free, outside screw and yoke (OS&Y) gate valve from the 611F-LF series, designed for full-bore shutoff in commercial and industrial piping systems. The body is cast iron with a cast bronze seat ring and stem trim, finished in epoxy powder coat for corrosion resistance. Packing is PTFE with a graphite gasket for reliable sealing across a wide temperature range of -20 to 406 degrees F. The flanged end style and 125 lb pressure class make it a standard fit for ANSI 125 flanged piping assemblies. A handwheel actuator provides direct manual operation. This valve is installed by licensed plumbers and pipefitters on water distribution, HVAC, and industrial process lines.

The 6GA-11A-B1-LF is suited for 4-inch nominal flanged piping in commercial and light industrial installations where lead-free compliance is required. With a rated flow rate of 1316 gpm and a pressure rating of 125 psi, it handles high-volume water service effectively. The OS&Y design provides a visual open or closed indicator, which is commonly required by fire protection and mechanical codes in commercial buildings. This valve is manufactured in the USA and carries a 125 lb pressure class rating consistent with ANSI flanged system standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter. Isolate and depressurize the system and drain fluid before removing any existing valve or installing this valve. Follow applicable codes including the International Plumbing Code and local amendments for flanged valve installation torque and gasket requirements. Verify flange bolt circle and face dimensions match the mating flanges before installation.
