Gadren Machine

Gadren Machine float valves are mechanical level controls for tanks, condensate receivers, cooling tower basins and water storage. The float rides on the water: as the level drops the float falls and opens the valve, and as the level comes back up the float closes it. The valve holds a set level with no power and no controller.

The Gadren Machine line on BoilerSupplies.com has four families. Globe and angle float valves come in heavy brass (ACF, AHF, GCF, GHF) and in 316 stainless steel (AHF-SS, GHF-SS). Globe and angle lever float valves come in heavy brass (ACLS, AHLS, GCLS, GHLS) and in stainless steel (AHLS-SS, GHLS-SS). Globe or angle is the body pattern. A globe body runs inline with the pipe; an angle body turns the flow 90 degrees. The brass valves come in a cold water and a hot water version. The stainless steel valves are listed for hot water. A lever float valve carries the float on a lever arm; the plain float valve carries it on a rod. Each model is listed complete and as valve only. Valve only replaces the valve and keeps the float and rod already in the tank.

Does a Gadren float valve go by ballcock, fill valve or make-up valve?

Yes, for the mechanical kind. Ballcock, ball cock, fill valve and float ball valve are the plumbing words for a float valve. Make-up valve is the boiler room word when it feeds a receiver or basin. A Gadren Machine float valve opens as the float drops and closes as it rises. Electric make-up valves and level controls are different parts.

What should I read off my old Gadren float valve before I order?

Its model code, if it is still readable, tells you globe or angle body, heavy brass or stainless steel, cold or hot water, and float or lever. Then say complete or valve only, the pipe size, the count, and the tank it goes on. With no code to read, send one photo of the old valve with its float and rod in place.

How do I tell a globe body Gadren float valve from an angle body?

Look at how the supply pipe meets the valve: a globe body is inline and an angle body turns the flow 90 degrees. A globe body takes the pipe in one side and out the other in the same line. An angle body suits a supply that comes down to the tank wall. Replace like with like, because the pipe is already run for one pattern.

What does valve only mean on a Gadren float valve listing?

Valve only is the valve without the float: the -V version of each Gadren model on BoilerSupplies.com. It fits a tank where the float and rod are still sound and only the valve sticks or leaks past a cut seat. Order the complete valve when the float is dented, waterlogged or missing.

How do I choose between the brass and the stainless steel Gadren float valve?

Match the valve coming out; the tank was set up for that material. BoilerSupplies.com lists both materials for hot water. The Gadren stainless steel valves (AHF-SS, GHF-SS, AHLS-SS, GHLS-SS) are listed for hot water; the brass valves come in cold water and hot water versions. On a new tank, the water treatment and the plant spec decide.
