The PfuZion Bonnet Assembly is a performance, reliability and maintainability upgrade for the ITT Pure-Flo Bio-Tek range of fractional diaphragm valves. A bonnet and diaphragm system that updates installed Bio-Tek valves to the most advanced technology available, assuring reliable performance and maintenance cost savings for years to come.
A new PfuZion diaphragm and bonnet assembly based on EnviZion valve technology, is mated to the existing in-service Bio-Tek valve body with a simple stud based conversion system. The one time conversion upgrades the valve to a quick connect system that assures error proof diaphragm installation and reduces diaphragm replacement maintenance time from 20-30 minutes to under well under 3 mins. Fastener re-torque after thermal cycling is a thing of the past as the integral thermal compensation system adjusts constantly to assure superior seal integrity.
The PfuZion Bonnet Assembly should be considered a “like-for-like” change, as product contact materials of construction, flow coefficients and rated seat and shell pressures remain unchanged.
