Replacing VEX, MEX, FEX valves and AVX, AVM actuators

Issue

Replacing VEX, MEX, FEX valves and AVX, AVM actuators

Product Line

Field Devices

Environment

Thermic Valves

Cause

The valve and / or actuator requires replacement.

Resolution

The AVX and AVM are a 2 wire thermic valve actuator, its stroke length is 2.5mm short stroke. The valve actuator fitting is an industry standard 30mm x 1.5mm thread.

To replace the valve use the VZ208 (2 port), VZ308 (3 port), VZ408 (4 port).

To replace the actuator use either the MZ140-24T (24Vac) or the MZ140-230T (230Vac).
