Mut Meccanica Tovo SF 3‑Port Spring Return Diverting Valve is a 28 mm compression motorised zone valve designed for high‑flow heat pump systems. It offers very low pressure drop, fast spring‑return operation and an integrated microswitch for simple control of auxiliary loads.

KEY FEATURES

28 mm 3‑port diverting valve – compression connections for straightforward integration into larger‑bore primary pipework on heat pump and cylinder circuits.
Spring‑return operation – fails to a safe default position on power loss, helping protect the system and simplify control strategies.
High Kvs value (12.6) – very low pressure drop, ideal for modern high‑flow, low‑temperature heat pump systems.
Integral microswitch – built‑in auxiliary switch for starting a secondary pump or signalling to a controller when the valve has reached position.
12‑month warranty – supplied with a 12‑month manufacturer’s warranty from date of manufacture.
APPLICATIONS

Diverting heat pump output between a hot water cylinder coil and a space heating circuit.
Use as a primary diverting valve in low‑temperature heating systems where low resistance is critical.
Replacing standard mid‑position or diverter valves where higher flow rates and reliability are required.
TECHNICAL OVERVIEW
