Manual Pinch Valve Series

Manual pinch valves feature a simple design that is easy to maintain and highly versatile. They are ideal for on-off applications with low cycling frequency involving solid-liquid and gas-solid mixtures. By selecting different sleeve materials, these valves can handle mildly corrosive, abrasive, and scaling conditions. They serve as effective alternatives to lined ball valves, diaphragm valves, and butterfly valves. For larger sizes, a handwheel mechanism can be added to reduce operating effort.
