Datasheet Check valve Type BCV With spring Type BCVA Without spring Nominal pressure PN 25/20/16/10 Nominal size DN 50 - 600 Material CF8M • Short face to face • Low weight easy installation • Low opening low pressure and pressure drop • Good tightness • Short closing time • Available with spring • Replaceable shafts The SOMAS check valve can be used on liquid, steam and gas. The check valve should be clamped between flanges. Pressure rating is PN 25, but the check valve can also be mounted between other standard flanges. The disc is supported by two shafts, which are replaceable when necessary. The shafts are sealed in the body by graphite gaskets. The closing time is short due to the seat angle in the body. When required, the valve can be equipped with spring(s) to shorten the closing time. For installation on liquids the version with spring(s) is recommended. Sizes DN 200 and upwards have a lifting eye for easy mounting.
