What Is a 3-Port Actuator Head?

A 3-port actuator head is a vital component of a mid-position motorised valve used in Y-plan central heating systems. It controls the flow of water between your central heating and hot water cylinder, ensuring both systems receive the correct water flow at the right time.

Instead of replacing the entire valve assembly, you can simply switch out the actuator head, saving both time and money. The ESI 3-port replacement head offers exceptional compatibility and performance, especially for systems originally fitted with ESI or industry-standard valves.

Easy Replacement Without Draining the System

One of the key benefits of the ESI 3-port actuator head is its detachable design. You don’t need to disturb the valve body or drain the system — just remove the faulty actuator and snap on the replacement head. This makes it an ideal solution for quick repairs and routine maintenance without the mess.
