Festo
8079857
Pinch valve VZQA-C-M22C-6-S5S5-V2V4E-4
The Festo 8079857 is a pneumatically operated structural pinch valve featuring a soft sealing principle and a 2/2-way, closed, monostable valve function with a nominal width DN of 6. This externally controlled component supports in-line installation in any mounting position utilizing a clamp connection according to DIN 32676 series A, handling a medium pressure range of 0 MPa to 0.4 MPa and an operating pressure of 0.35 MPa to 0.6 MPa with a mechanical spring reset. It operates with compressed air or water up to a maximum viscosity of 4000 mm²/s, with medium pressure vacuum testing conducted up to -0.09 MPa at room temperature.
