Georg Fischer Butterfly Valve Wafer Type

Specifically for water applications, the Type 563 Aqua Georg Fischer Butterfly Valve operates at pressures of up to 150 PSI and can handle temperatures from 32°F to 142°F. The wetted inner body made of PVC with EPDM seals. Because of the plastic body, the Aqua Valve is lightweight and installs easily between flanges. The Aqua Valve is compatible with ANSI and DIN flanges and is available from 2″ to 12″. The Q-ring seals allow the valve to install without additional gaskets.

Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve’s name is based from the functionality of its disc. There are a few different types of butterfly valves, however, they fall into two basic types – Lug and Wafer valves.

Metal butterfly valves usually use for control and on/off operations. Due to the fact, that the valves are available with different body designs (wafer or lug type) and materials, they perfectly meet the requirements of diverse applications and processes.

Type 563 Wafer Style Georg Fischer Butterfly Valve

The Type 563 Butterfly Valve shall be wafer style compatible with both ANSI B16.5 150 lb and DIN 2501 flange patterns. The disk operation shall utilize double eccentric design principles.
The shaft shall be non-wetted by a bushing assembly with double O-ring seals and fixed at both ends. The face seal shall be a Q-ring compatible with flat and serrated flange adapters. The face, disk and shaft seals shall operate independently. The wetted body and disk shall be of like materials. The handle shall be lockable with standard adjustment increments of 5 degrees. The operator mounting flange shall comply with ISO standards. All valves shall be tested in accordance with ISO9393 and designed to ISO16136 standards. All valves shall be manufactured under ISO9001 for Quality and ISO14001 for Environmental Management. Following assembly, every valve shall be tested and certified bubble-tight exceeding Class VI standards.
