CQF Series – DIN

The CQF DIN Series is a 3/4/5-way floating ball valve specifically designed for cryogenic applications. It allows for different ball port configurations with “L”, “T” or “X” options and with isolation at every port. Available with welded, threaded or flanged CL150 and CL300 end connections, this valve is manufactured in stainless steel. Additionally, the valve features TFM1600 soft seats and is available in both full and reduced bore configurations. It is very versatile, easy to operate, and incorporates low fugitive emission design, fire safety design, and antistatic design features.
