[b]Fusible Link / Fire Valve / thermal actuator[/b]
(OP)
I'm trying to find manufacturer/Supplier for fusible link actuator to be installed on 3" and 4" groves class 600 or if they have the complete valve +actuator that will be considered too, one feature I'm looking for is the ability to override the fusible link and operate the valve manualy.
Any recommendations or suggestions?
Thanks

There's many option available regarding this. When you use inteligent electric actuators such as INTELLI+, MX Series or IQ series (BERNARD, LIMITORQUE AND ROTORK), normally, you can set-up them in order to override automatically the fusible link. There are more expensive than normal equipment, but be sure that they will shut-off (or open) the valve automatically. Single restriction is ambient temperature.

Thank you for you reply, and maybe I didnt clarify exactly what I'm looking for, basiclly it is a thermal actuator which triggers (close - in case of fire) at a preset temperature let say 190 degF), and my client is not looking for a remote controlled one (cuz of cost, as we'll need 4 of them)
I havent looked into Limitorque, or Rorork yet, but as far as I know they had only electrically controlled actuator- w/manual override, i.e control, status, etc. r done through electrical signal to the RTU. Is that right?
Cheers

Intelligent actuators has the option, when temperature becomes so high, to override the thermal protection and goes to failsafe position (open or close), but only "INTELLIGENT" series. These are non-intrusive equipment.
Maybe you can use to use an bimetalic thermometer (direc mount or with capillary) with microswitches. You can select trigger-point (or points) and arrange the circuit. Check at DeWIT or ASHCROFT options.
