The Mut Meccanica Tovo 2‑port zone valve 28mm compression is a high‑flow motorised zone valve designed for heat pump systems, combining low pressure drop with robust spring‑return operation and an integral microswitch for auxiliary load control.

Key Features

• 28 mm compression connections – direct connection to 28 mm copper pipework with supplied nuts and olives, ideal for larger‑bore heat pump circuits.
• 2‑port zone valve – simple ON/OFF control of flow to a single zone or circuit, commonly used for isolating heating or hot water zones.
• High Kvs 10.0 – very low pressure drop, supporting the high flow rates and low temperature differences required by modern heat pump systems.
• Integral microswitch – built‑in auxiliary switch for controlling secondary loads such as a secondary pump or providing a signal back to a heat pump or controller.
• 12‑month warranty – supplied with a 12‑month manufacturer’s warranty from date of manufacture.

Technical Overview

• Product code: 7.001.02778 (Mut Meccanica SF 2‑port motorised zone valve).
• Valve type: motorised 2‑way zone ball valve with spring return and auxiliary microswitch.
• Flow coefficient: Kvs 10 m³/h at a differential pressure of 1 bar.
• Rated pressure: PN10, suitable for typical sealed heating and heat pump systems.
• Fluid temperature range: suitable for standard heating system operating temperatures within the valve specification.
• Power supply: 230 V a.c. actuator (typical low‑watt motor drive, model dependent).

Applications

• Heat pump zone control – zoning or isolating individual radiator, underfloor or cylinder circuits on high‑flow, low‑temperature systems.
• DHW / heating separation – use as a zone valve to prioritise hot water or specific heating zones when driven from a controller or heat pump relay.
• Auxiliary pump switching – use the microswitch to start a secondary circulation pump or provide an “on” signal when the valve reaches the open position.

Installation Notes

• Install on clean, flushed pipework and follow the marked flow direction on the valve body.
• Wire the actuator and auxiliary microswitch in line with the manufacturer’s wiring diagram and the relevant heat pump or zone control schematics.
• Ensure pipework is adequately supported and the actuator is protected from excessive heat, moisture and condensation.
