EVURU 2/2 DN25 SS Electric Water Valve Instruction Manual

1. Introdución

This manual provides essential information for the safe and efficient installation, operation, and maintenance of your EVURU 2/2 DN25 Stainless Steel Electric Water Valve. This valve is a normally closed, direct-acting solenoid valve designed for controlling the flow of water, gas, or liquid in various applications.

Please read this manual thoroughly before installation and operation to ensure proper function and to prevent damage or injury. Keep this manual for future reference.

2. Información de seguridade

AVISO: Failure to follow these safety instructions may result in property damage, serious injury, or death.

• Always disconnect power before installing, servicing, or cleaning the valve.
• Asegúrese de que o voltage supply matches the valve's specified voltage (e.g., AC220V, DC12V). Incorrect voltage can damage the valve or cause electrical hazards.
• Installation should be performed by qualified personnel in accordance with local electrical and plumbing codes.
• Do not exceed the maximum working pressure specified for the valve.
• Ensure the media (water, gas, liquid) and its temperature are within the valve's specified limits.
• Usar o equipo de protección individual (EPI) axeitado durante a instalación e o mantemento.
• Avoid exposing the valve to corrosive environments or extreme temperatures outside its operating range.

3. Produto rematadoview

The EVURU 2/2 DN25 SS Electric Water Valve is a robust solenoid valve constructed from Stainless Steel 304, designed for reliable flow control. It features a 1-inch pipe size (DN25) and is available with BSP or NPT threads. The valve operates as normally closed, meaning it remains closed when de-energized and opens when energized.

4. Configuración e instalación

4.1 Comprobacións previas á instalación

• Verify that the valve specifications (voltage, pressure, media, temperature) match your application requirements.
• Inspeccione a válvula para detectar calquera dano visible derivado do transporte.
• Ensure the piping system is clean and free of debris that could obstruct valve operation.

4.2 Instalación mecánica

1. Turn off the main power supply and shut off the fluid flow to the installation area.
2. Identify the inlet and outlet ports on the valve body. Flow direction is typically indicated by an arrow on the valve body.
3. Apply appropriate thread sealant (e.g., PTFE tape or pipe dope) to the pipe threads.
4. Thread the valve onto the pipes, ensuring a tight, leak-free connection. Do not overtighten.
5. Mount the valve in a position that allows for easy access for maintenance and inspection. The solenoid coil should ideally be in an upright position to prevent accumulation of debris and ensure proper operation.

4.3 Conexión eléctrica

1. Asegúrese de que a fonte de alimentación estea desconectada.
2. Connect the valve's electrical wires to the appropriate power source. Refer to the voltage specified on the solenoid coil.
3. Asegúrate de que todas as conexións eléctricas estean seguras e debidamente illadas para evitar curtocircuítos ou riscos eléctricos.
4. If applicable, connect the ground wire according to local electrical codes.

5. Instrucións de funcionamento

The EVURU 2/2 DN25 SS Electric Water Valve is a normally closed (N/C) valve, meaning it is closed by default when no power is applied to the solenoid coil.

1. Para abrir a válvula: Apply the specified electrical voltage to the solenoid coil. The coil will energize, lifting the plunger and opening the valve, allowing fluid to flow.
2. Para pechar a válvula: Disconnect the electrical voltage from the solenoid coil. The coil will de-energize, and the plunger will return to its closed position, stopping the fluid flow.

Ensure that the system pressure and fluid temperature remain within the valve's specified operating limits during operation.

6. Mantemento

Regular maintenance helps ensure the longevity and reliable operation of your valve.

• Inspección periódica: Regularly check for any signs of leaks around the valve body and connections. Inspect the electrical wiring for damage or loose connections.
• Limpeza: If the valve is operating in an environment with particulate matter, periodic cleaning of the internal components may be necessary. Always disconnect power and depressurize the system before disassembling the valve.
• Substitución do selo: Over time, the EPDM seals may wear out. If leaks occur or the valve fails to seal properly, the seals may need to be replaced. Refer to Figure 2 for component identification.
• Inspección da bobina: Ensure the solenoid coil is free from excessive heat, moisture, or physical damage.

Note: For complex repairs or internal component replacement, it is recommended to consult a qualified technician or the manufacturer.
