Valve Kit

The VK21 Valve Kit is comprised of a bracket, coupler and valve. Several configurations are shown below with widely used valves. ETI can make specific recommendations if you describe your application in the Design Guide form.

The flexibility and simplicity in actuator to valve stem coupler design means longer rotational valve life and valve interchangeability in the field. A new universal coupler allows for both angular and offset misalignment of actuator shaft and valve stem, greatly reducing side load on the valve stem.

Straightforward design and simple calibration requirements make changing valves possible at the customer level.
