Mut Meccanica Tovo SV 28mm 3 Port Diverter Valve with Microswitch

Description

The Mut Meccanica Tovo SV is a high performance 28mm compression 3 port diverter valve designed for heat pump and renewable heating systems. This spring return motorised valve delivers exceptionally low pressure drop (Kvs 12.6 m³/h), making it ideal for high flow applications where efficiency and reliability are critical.

Supplied with an integrated microswitch, the Tovo SV enables seamless control of auxiliary loads such as secondary circulation pumps, ensuring precise system management for both domestic and commercial installations.

Key Features

Ultra Low Pressure Drop
Kvs value of 12.6 m³/h ensures minimal flow resistance, optimising heat pump performance and energy efficiency.

Integrated Microswitch
Built-in auxiliary switch (3 A, 250 V AC) for controlling secondary pumps or other loads without additional components.

Spring Return Mechanism
Failsafe operation returns valve to default position on power loss, protecting system integrity during outages.

Robust Construction
Brass valve body with stainless steel springs and self extinguishing ABS motor housing for long term durability.

Wide Temperature Range
Operates reliably with flow temperatures from +5 °C to +110 °C, suitable for diverse heating applications.

Easy Manual Override
External lever allows manual positioning for system filling, draining, or maintenance without power.
