VZQA controls media flow
Individually configurable components.
Festo’s VZQA pinch valve is an alternative to diaphragm and ball valves in many process automation applications for controlling and shutting off a wide range of media flows, such as liquid, fibrous, particulate or granular.
Full bore passage minimizes flow resistance, preventing the valve from becoming blocked or clogged, so media flows freely. This also supports hygienic process sequences and cleaning cycles.
They’re simple mounting, compact space-savers and operate via direct air supply.
There are two versions: normally open (N/O) for media pressures from 0 to 4 bar and a normally closed (N/C) for 0 to 6 bar media pressures.
The N/C version is the first pinch valve on the market with an integrated actuator, and the aluminum variant is the first to offer ring positioning via a ring magnet in the piston.
The components of the VZQA are individually configurable, whether it’s connection types, materials or pinch valve sleeves.
The sealing cartridge is replaced without special tools, but this might only become necessary after approximately one million switching cycles.
