Betts Compact Mechanical Operators function cable-operated emergency valves from a central location on a cargo tank. Provision is made for mounting a 3-way air valve (part no. 20761) on the side of the operator. The air valve is actuated when any compartment is opened, thereby assuring that air vents are energized when any emergency valve is opened. The air valve is not included. Add the suffix “003” to include the air valve. Available from 1 up to 5 compartments in stainless or powder-coated steel; each compartment is supplied with a fusible link designed to melt at not more than 250°F as well as non-slip cable connectors that allow the cable to be cut to length after installation.
Features & Benefits
The new design is more compact than comparable Universal or Deluxe models. Slotted mounting straps are available as an option to allow for the replacement of Deluxe operators without drilling new mounting holes. Specify straps by adding the suffix “001” to the assembly number. Other mounting options are available by contacting sales.
Lever arms provide 2-3/8” stroke and 5.6:1 mechanical advantage. Two trip levers are provided for flexibility in locating cable remote control or for attaching two remotes if required. See Section 29, Page 1A for the cable remote control.
