2-way N.C. solenoid valve 1/4" + 230Vac coil mounted – code: M78076U_B – Climma

2-way N.C. 1/4" solenoid valve with 230Vac coil mounted (Climma) – M78076U_B

The’2-way normally closed (N.C.) solenoid valve with 1/4" threaded connections and 230Vac coil already mounted is a spare part identified by the code M78076U_B (Climma). It is a two-way solenoid valve designed for the automatic management of fluid flow within technical circuits, typically in the field of air conditioning and refrigeration.

The operating logic is typical of N.C. solenoid valves: in the absence of power the valve remains closed, while when the coil is powered at 230 V AC it generates the magnetic field necessary to open the valve and allow flow in the circuit. This configuration is commonly used when it is desired that, at rest or in case of power failure, the fluid flow is interrupted.

Features and construction details

The model M78076U_B is supplied as a complete solenoid valve, with coil already installed, to facilitate replacement and restoration activities on existing systems. The available information clearly identifies configuration, rest state, and type of connection.

• Supply: bobina preassembled/mounted on the valve, ready for installation.

Product identification

• Product code: M78076U_B.
• E-commerce SKU: VECO00000071.
• Supplier: VECO S.P.A..

Typical applications (air conditioning and refrigeration)

This solenoid valve is used as a control component to manage the opening and closing of a line, automatically, in systems where fluid control is entrusted to an electrical/electronic logic. In HVAC/R, the solenoid valve can be used to intervene on circuit sections according to the operational requirements of the system.

Where it is used

• On air conditioning systems and refrigeration where it is necessary to control the fluid flow.
• In circuits where a control unit or an electrical command requires’interception or enabling of the flow.
• As replacement for replacing the original solenoid valve in case of failure or malfunction.

Function in the circuit

• Automatic control of fluid flow in the circuit.
• Opening/closing of refrigeration or hydraulic lines based on the electrical command.
• Support for automatic operation of the system based on the signals from the control unit.

Operational advantages

In a technical spare parts context, these aspects help maintain consistency with the system and simplify maintenance activities.

Why choose a 2-way N.C.

• Defined resting behavior: with coil unpowered the valve remains closed, interrupting fluid flow.
• Simple command management: opening occurs when the coil is powered, allowing typical on/off control of solenoid valves.

Practicality in maintenance

• Coil already mounted: ready-to-install solution, useful in replacements where assembly operations need to be minimized.
• Clear identification code: the presence of the code M78076U_B facilitates correct identification of the spare part.

Usage and installation notes

For correct use, it is important to verify the spare part matches the intended application and to follow the system's instructions where the intervention is made. In particular, since this is a solenoid valve with a coil at 230Vac, it is essential that the power supply and control are consistent with the system's requirements.

Operational notes

• Compatibility check: check that the code M78076U_B is the one specified as a spare for the unit/system.
• Connections: checking the presence of 1/4" threading on the circuit to ensure correct installation.
• Power Supply: use exclusively command and power consistent with the 230Vac coil.
• Security: operate the system under suitable conditions and with electrical power managed according to the prescribed maintenance procedures.

Replacement indication

In case of replacement, the solenoid valve is normally used to restore the correct operation of the circuit when the original component is faulty or no longer efficient. To avoid errors, it is advisable to rely on product code, configuration (2-way, N.C.) and type of connection (1/4″).

FAQ – Frequently Asked Questions

What does “normally closed (N.C.)” mean in this solenoid valve?

It means that when the coil is not powered, the valve remains closed and prevents the fluid from passing through. When the coil is powered, the valve opens allowing flow in the circuit.

Is the coil included in the supply?

Yes. The product is indicated as a solenoid valve with 230Vac coil already mounted, ready for installation.

What is the valve connection type?

The solenoid valve is equipped with 1/4″ threaded connections.

In which systems is it typically used?

It is used in air conditioning and refrigeration systems to automatically control the flow of fluid in the circuit, managing the opening and closing of a line based on the electrical command.

How can I check if it is the correct replacement?

Check the product code (M78076U_B) and verify that the configuration (2-way, N.C.), 1/4″ connections, and 230Vac coil power supply match the system you need to work on.
