Introducing the Emmeti Return Pin Valve which is a precision-engineered device that connects to the manifold of an underfloor heating system. It features an actuator that responds to the thermostat settings for each zone, controlling the opening and closing of the valve based on the desired temperature. This pin valve is a direct replacement for the brass and stainless manifold which is commonly found in older and newer systems and has been branded under names such as Myson, Purmo, Emmeti, Even Heat, Nu Heat, Ambiente, Komfort, and others.
