The ESi ESZVA2LM provides a highly efficient motorised actuator replacement for domestic central heating zone valves. Designed to fit securely onto both 22mm and 28mm brass bodies, this 0.55kg unit offers a direct, universally compatible alternative to several popular mainstream brands. Measuring 102x123x81mm, the compact plastic chassis houses a robust motor mechanism that accurately dictates the directional flow of primary heating fluid across independent thermal zones.
A critical engineering advantage of this specific model is the tool-free, detachable mounting system. Installers can rapidly switch out a failing actuator head without draining down the entire primary circuit, vastly reducing onsite labour time. The latest iteration of this control head omits the standard plug-in lead, meaning the unit must be hardwired directly into the local wiring centre or junction box to establish electrical continuity. This straightforward approach to replacement ensures minimal disruption for the end-user while maintaining precise thermostatic control across the property.
Q: Does this actuator require the primary circuit to be drained?
A: The tool-free detachable design allows for immediate replacement without depressurising the wet system.
Q: What size valve bodies is this head compatible with?
A: The universal base plate is engineered to fit both 22mm and 28mm valve assemblies.
Q: Can this unit be plugged directly into an existing socket?
A: No, the latest design requires the electrical flex to be hardwired into a junction box.
Q: What are the exterior dimensions of the plastic casing?
A: The actuator shell measures 102mm in height, 123mm in width and 81mm in depth.
