With the V221 no longer available (withdrawn in 2004) a replacement valve is requested.
Replacing existing installed V221 valves
V221 can be replaced by VG221F and V222. Flange bolt pattern and measurements should be the same (designed according to DIN standards), and actuator (Forta) can be used with the exception of V222 DN125-DN150 where M22/M50 is required.
Please see each products data sheet for more information and details.
