The Model 792-20 on/off pinch tube valve is higher flow rate design with needle block outlet to dispense continuous bead or potting applications.
The Dispensit© Model 792-20 pinch valve is engineered to dispense a continuous bead or potting in low-pressure feed applications. It can dispense a wide range of water-thin to medium viscosity material and is engineered to prevent material loss during operating air pressure drop. The model 792-20 valve is engineered to eliminate material waste by use of a spring-held pinch bar that closes with air pressure drop.
