Plastic Diaphragm Valves

Multi-Turn Valves for Everything from High Purity Water to Corrosive Slurries

Diaphragm valves are excellent for flow control due to their high degree of adjustability and resistance to clogging.  Whether your system is handling the highest purity water or the most corrosive chemical compound or slurry, Simtech diaphragm valves are built to seal tight and last long.
