Applications:
•
The process control head is fitted for the controlling of
pneumatically operated process valves. The design of the
valve body eleminates dead space, a prerequisite for sterile
process engineering. When working with high sterilization
temperatures this valve fulfills demands for operational
security and reliable function.
Features:
•
valve body made from solid bar
•
no dead spaces
•
drainable when mounted in various positions
•
complete separation from environment
•
no dome or sump in product space
•
change of seals without special tools
•
minimum 500,000 strokes
•
optimum cleanability
•
long life of the PTFE bellows
•
low spare part costs
Valves can only be quoted when full application data is supplied: product viscosity, temperature, inlet and
outlet pressure or process pressure, line size and desired product flow.
