Our hand expansion valves are available in a globe design to work with pipe sizes from ¼” to 1 ¼” and in an angle design to work with pipe sizes from ¼” to 1”. They come with zinc-plated carbon steel (-CS) or stainless steel (-SS) stems. The valve body materials are ductile iron or C.I. 40 and are pressure tested for leakage after assembly.
