QF – ASME
The QF ASME Series is a 3/4/5-way sanitary floating ball valve specifically designed for industrial applications. It allows for different flow switching schemes with “L”, “T” or “X” configuration and with isolation at every port. Available with connections for welding, threaded connections or even flanges CL150 and CL300, this valve is available in carbon steel as well as stainless steel. The valve features as standard C-RPTFE soft seats and is available in both full and reduced bore configurations. It is very versatile, easy to operate, and incorporates low fugitive emission, fire safety design, and antistatic design features.
