Issue
V355 is obsolete since 2002
Environment
V355
VZ22
VZ32
MZ18
MZ10
Cause
V354 and V355 was made obsolete in 2002. No direct replacement is available.
When replacing the V355, the actuator must also be replaced.
Resolution
V355 is replaced by a VZ32, or VZ22 (2 port) depending on application. Pipe work is required as the ports are placed differently.
Replacing the actuator is also necessary. VZ*2 is using the MZ18 or MZ10 actuator.
