Festo
8172745
Pinch valve VZQA-C-M22U-50-GG-V2V4E-2
The Festo 8172745 is a pneumatically operated structural pinch valve featuring a soft sealing principle and a 2/2-way monostable open valve function with a DN 50 nominal width and G2 fitting connection. Designed for in-line installation in any mounting position, this externally controlled component supports a medium pressure range of 0 bar to 2 bar, an operating pressure of 0 bar to 4.5 bar, and reversible flow direction, with vacuum usage tested up to -0.09 MPa at room temperature. Reset is achieved via rebound resilience against a differential pressure of 2.5 bar, a burst pressure of 16 bar, and an overload pressure of 7.8 bar within a PN 10 nominal pressure fitting.
