Festo
4748311
Pinch valve VZQA-C-M22C-6-TT-V2V4E-4
The Festo part number 4748311 is a pneumatically operated, 2/2-way closed monostable pinch valve featuring a soft sealing principle and an in-line installation design with 1/4 NPT fitting connections and a nominal width DN of 6. It supports a medium pressure range from 0 to 0.4 MPa, an operating pressure of 0.35 to 0.6 MPa, and handles compressed air or water with a maximum viscosity of 4000 mm²/s across any mounting position. The component utilizes an M3 auxiliary pilot air port 12, mechanical spring reset, and reversible flow direction, with vacuum usage tested up to -0.09 MPa at room temperature.
