Georg Fischer 5-Series Type 514 Diaphragm Valve
TF:
002879-HW-GF-079
Overview
The Georg Fischer 5-Series Type 514 Diaphragm Valve utilizes a threaded bonnet to valve body connection, in place of traditional metal body bolts. The all-plastic connection of the 5-Series Type 514 has a higher thermal expansion rate than such metal components, eliminating the need for retorquing after hot line shut downs.
- Temperature:
- PVC: 32 to 140ºF (0 to 60ºC)
- CPVC: 32 to 176ºF (0 to 80ºC)
- 150psi maximum pressure
- Lockable handle
- Stainless steel mounting inserts
- Threaded bonnet to body connection
- PVC meets ASTM D1784 cell classification
- CPVC meets ASTM D1784 cell classification 23447-B standards
The plastic material is also ideal for applications in which corrosive chemicals are present in the atmosphere. The elimination of valve body bolt holes also decreases the grade of the weir and optimizes flow path. This significantly increases the Cv value when compared to traditionally designed diaphragm valves.
