DJ Gongol and Associates represents the GA Industries line of butterfly valves. Golden Anderson (today under the GA Industries company name) has a long and storied history in the water flow-control market, and their butterfly valves are built to the same high standards that built the name.
GA Industries butterfly valves are fully compliant with the AWWA C504 standard. In sizes from 3" to 24", GA Industries butterfly valves are built in a ductile iron body with a fully rubber-lined integral seat.
The upper and lower bearings are self-lubricating stainless-steel-backed PTFE for low friction and long life.
