Product description Ball Valve Type 543 Pro is the perfect valve for all mixing and diverting processes. The availability in horizontal design with L or T-ball and vertical design with L or tripod ball makes many application options possible. Diverting, mixing, distributing or even shutting off a medium are only a few possibilities. Applications • Chemical process industry • Seawater desalinization systems • Life science industry • Water treatment • Diverting function in shipbuilding Benefits/features • Lockable lever as standard (lockable every 90°) • Electric position feedback via NPN/PNP/Namur Sensor • Data Matrix Code on every valve • Ideal diverting and mixing fitting • Ball with L-port / T-port • Lever material made of fiberglass-reinforced polypropylene (PP-GF) • 90° end stop standard, 180° end stop on request • Tool integrated into lever • Very good flow properties • Long service life • Automation with electrical or pneumatic actuator possible Flow media Neutral and aggressive media with a small amount of particles/solids. The chemical resistance depends on the selected valve material (see online tool ChemRes PLUS). GF Piping Systems - Industrial Piping Sys

Technical basics • With the backing seals, the ball has a floating position. This results in preloading and hence a constant seal. Stem, housing and connection seals are made of EPDM or FKM. • The stems with rated break point above the upper O-ring help prevent leaks to the outside in case of damage. • The design of the hand lever serves as a tool for installing the screw-in fitting. Screw-in fittings have a reverse thread in order to avoid unintentional opening when removing the coupling nuts or the thread connections. All ball valves in DN10 – 50 are available as radially removable fittings...

Versions The Ball Valve Type 543 Pro is available as a horizontal and vertical version. The horizontal valve can be ordered with L- or T-port ball. The vertical fitting comes in the L-port configuration or with a optional tripod ball. Type 543 Pro, horizontal The decision whether to use a 3-way ball valve with L-port or-T-port depends on the desired functions the valve has to perform: B L-port: diverting, shutting off (two inputs closed) T-port: diverting function, mixing function, throughput Diverting function in the Mixing function with base position decreased flow Diverting function Outlet...
