Modulating Valves
Accurately control the flow and pressure of your process with modulating valves from SPI. They come in a variety of options, including multi-taper, straight taper, or hand-operated.
Made of an entirely stainless-steel construction — with 316L wetted parts — these valves meet 3-A requirements. Valves are available in sizes 1", 2", 2.5", and 3" with five additional Micro Flow options for precise control of low flows.
