Note for Valve:
Note 1: The model with “*” means maximum differential pressure of VB-72(3)00-65 fitted with VA-3200 actuator.
Note 2: Add “Q” behind model number indicates Easy Installation type valve. The Easy Installation Actuator can only be installed on Easy Installation type valve. If Easy Installation type valve is required on steam valve, radiator is not available.
Note for Actuator:
Note 1: “●” means “with”;
Note 2: With manual switch, add “M” behind the model, for example: VA-7100M With easy installation device, change the second “1” to “3” and second “2” to “4”, for example: VA-7300, VA-7400
