4-way valve thermal actuator 230V 50/60Hz with cable L=2mt - code: M76656 - Climma

Thermal actuator for Climma 4-way valve: spare part with traceable codes

This thermal actuator for 4-way valve is a spare part component intended for technical systems where flow regulation occurs via hydronic valves. It is offered as a spare part in the Climma and is identifiable by code M76656 (also referencing the supplier product code M88675), useful detail for checks on the bill of materials, plant documentation, and targeted replacements.

Power supply is indicated as 230V 50/60Hz and the actuator is supplied with included cable of length L=2 m, practical solution when working in technical spaces or during maintenance, reducing the need for extensions or unwanted adaptations.

Features and construction details (based on available data)

Type: thermal actuator (electrothermal)

A thermal actuator is the element that mechanically controls the opening or closing of a valve. In this type, the movement is not entrusted to gears but to an electrothermal principle: the actuator receives power when the control (for example a thermostat or plant logic) requests intervention on the valve, generating a pushing action that brings the valve to the desired position.

This solution is commonly used in systems where a simple control suitable for regulation cycles typical of air conditioning and hydronic management is sought.

4-way valve: flow management and diversion function

The actuator is designed to work on a 4-way valve in a water circulation circuit. In many technical installations (including onboard applications), the 4-way valve is used to manage the flow to a user (for example a fan coil unit) and, when necessary, divert the flow to an alternative path (bypass/return) to maintain the overall circulation of the system more regular.

In practice, when a zone no longer requires heat exchange, the valve can limit the supply to the user and direct the flow consistently with the circuit architecture, avoiding simply “closing” the passage without managing the path.

Electrical data and wiring

• Power Supply: 230V 50/60Hz.
• Included cable: length L=2 m, useful for connections during replacement and maintenance.

Since the indicated voltage is the mains voltage, installation and connection must be carried out according to safety practices and procedures provided by the system being worked on.

Product identification and codes

For correct spare parts, code matching is often the determining factor. This item is identified by:

• Code: M76656
• Supplier product code: M88675
• Supplier: VECO S.P.A.

In professional contexts (nautical/onboard system installation and technical maintenance), correctly reporting these references simplifies procurement and reduces the risk of ordering a non-corresponding component.

Typical applications

This actuator is indicated as a spare part for systems where one 4-way valve regulates the hydronic supply to a user (such as a fan coil unit) and manages the flow diversion when the demand of the individual zone changes.

In particular, it is relevant for:

• Maintenance and restoration of air conditioning systems and hydronic circuits where a 4-way valve is present.
• Interventions on individual zones (cabins/environments) when local flow regulation does not respond correctly.
• Spare parts with code verification, when the system documentation requires a precise part number.

The presence of 2 m cable can facilitate installation in technical compartments or in positions where the connection point is not immediately adjacent to the component.

Operational advantages (without unverifiable claims)

• Identifiable spare part: the codes M76656 and M88675 support a safer selection of the component during ordering.
• Practical wiring: cable included, useful for replacements and maintenance interventions.
• Suitable for hydronic systems with 4-way valve: designed for valve control and flow management towards the user.
• Consistency with technical contexts: component oriented towards professional systems and spare parts, where traceability is central.

Usage and notes for installation/maintenance

For a correct replacement, it is advisable to operate with a “by code” and “system verification” approach:

• Code verification: compare the code present in the bill of materials or on the replaced component with M76656 (and, if useful, with the reference M88675).
• Check power supply: ensure that the system provides power 230V 50/60Hz for the actuator.
• Wiring management: use the 2 m cable in an orderly manner, avoiding mechanical stresses on the connection and respecting the connection methods provided by the system.
• Safe intervention: since this is a component powered by mains voltage, perform operations with the system in safe conditions and according to applicable procedures.

If the system shows localized symptoms (for example, a single user that does not properly regulate water flow), the actuator is one of the components typically checked during diagnosis, always in combination with the valve and control checks.

FAQ – Frequently Asked Questions

What is the correct code to identify this actuator?

The product is identified by code M76656. The supplier reference M88675 is also available, useful for comparisons with documentation and bill of materials.

What power supply does the actuator require?

The indicated power supply is 230V 50/60Hz. Before installation, it is advisable to verify that the system provides this voltage for the actuator.

Is the cable included?

Yes, the actuator comes with a cable included, length L=2 m, designed to facilitate connection during replacement.

What is the purpose of a thermal actuator on a 4-way valve?

It is used to mechanically control the valve, managing the opening/closing and flow diversion in a hydronic circuit towards the user (for example, a fan coil) or towards an alternative path provided by the system.

How can I avoid compatibility errors when ordering?

The safest method is to verify the correspondence of the codes (M76656 and/or M88675) with those on the existing component or in the system documentation before proceeding with the purchase.
