ESi ESZVA2LM Two-Port Zone Valve Actuator Head

The ESi ESZVA2LM is a replacement actuator head for two-port zone valves. This listing is for the actuator head.

ESi describes this model for 22mm and 28mm two-port zone valves, including some other manufacturers’ valve bodies. That does not mean it fits every valve of those sizes or every other-brand body.

Before ordering, check the existing valve body model, actuator generation, mounting arrangement and wiring against ESi’s ESZVA2LM instructions and compatibility guide. Do not assume LM and PM heads, or different valve generations, are interchangeable.

The head has a manual lever for filling and draining operations. Have replacement and electrical connection carried out by a suitably qualified installer following the manufacturer’s instructions.
