These VAT valves are listed by size. We have pneumatic, manual and stepper versions available for most types since VAT has made them in a modular fashion. Valves that have stamped model numbers are listed with the whole number. Each valve can be described with the coded model number.
The first two numbers in the model tells the series. The difference of the series 14.0 valve is that it is constructed for easy maintenance where the series 10.8 is made to handle a higher bakeout temperature. The series 64.0 is similar to the 14 but is a throttling control valve.
The series 15.0 is a particle free valve.
The series 12.1 is a low cost aluminum version.
The series 20.0 is a compact alternative called the Vatterfly.
