Series Air Pinch of air operated pinch valves, available form Valves Online , have been specifically designed to control the flow of contaminated fluids or slurries. Pilot pressure is required but can be in the form of air or fluid and liquids such as water.
The Series Air Pinch valves operates in the same way, using air or liquid pressure at the control inlet to collapse the internal rubber sleeve to provide immediate and positive shut off capabilities. The rubber sleeve shuts entirely even on large particles, abrasive as well as corrosive materials. The sleeve allows full and unobstructed flow when opened, with minimal turbulence.
ValvesOnline offers easy replacement of sleeves when they wear out.
