Type 546 Pro Ball Valve


The Type 546 Pro is the flagship valve of Georg Fischer Piping Systems and offers a broad range of material and accessory options to suit most industrial ball valve applications.

The Type 546 Pro utilizes standard industrial thermoplastic ball valve features such as design stem break point and a reverse threaded seat carrier while incorporating new features such as a trackable laser engraved data matrix and a unique lockable handle design.
