Mississauga, Ont. – The VZQA pinch valves from Festo have full bore passage and are a cost-efficient, energy-efficient and easy to clean and service alternative to diaphragm and ball valves in many process automation applications.
The company says are a clean, reliable and straightforward solution for controlling and shutting off a wide range of media flows, whether 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 provides optimal support for hygienic process sequences and cleaning cycles. They are simple-mounting, compact space-savers, and operate via direct air supply.
The VZQA pinch valves come in two versions: a normally open (N/O) version for media pressures from 0 to 4 bar and a normally closed (N/C) version 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 of the N/C 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 can be replaced without special tools, but depending on the application and operating conditions, this might only become necessary after approximately one million switching cycles.
