W9TW Taylor Wedge Diaphragm Seal
Reotemp’s Taylor Wedge Diaphragm Seal is designed with a diaphragm welded to the upper housing and bolted together to an existing wedge meter. This removable design allows for easy cleanout of the wedge chamber, while still maintaining the system fill. The Taylor Wedge diaphragm seal can be adapted to fit almost any pressure instrument and process condition.
- Welded Diaphragm for Maximum Durability
- Wide Variety of Diaphragm and Material Options
- Continuous-duty Protects from Process Fluid Leaking in the Event of a System Breach
- Easy Cleanout of Diaphragm Cavity without Compromising Filled System
