Abstract:
1. A pneumatic pinch valve for compressing tubing formed of compressible material, the pinch valve comprising: a housing comprising: a headpiece having a first headpiece end, a second headpiece end, and a headpiece slot for receiving a portion of tubing formed of compressible material, wherein the first headpiece end is removeably attached to the housing so that the plunger resides within the headpiece slot, the headpiece slot including a headpiece surface at the second headpiece end against which the portion of tubing is compressed by the plunger when in a closed position, wherein the at least one spring urges the plunger into the closed position by exerting a force on the piston plate and a gas injected into the pneumatic chamber urges the plunger into an open position by exerting an opposing force on the piston plate and compressing the at least one spring to relieve compression of the portion of tubing, and wherein the portion of tubing is removeably held in the headpiece slot by the headpiece surface when the plunger is in the open position.
