Technical Data Sheet: Fantini Bronze Solenoid Valve DN65 with Flanged Connection

General Description

The solenoid valve in question is a Fantini DN65 , built in 2015 and never used. It is a fundamental hydraulic component for fluid flow control, particularly suitable for applications where automatic, rapid and reliable flow control is required in industrial piping systems. This specific solenoid valve is designed to be used with bronze compatible fluids, such as water, oils and non-corrosive gases.

Main Components

1. Valve Body:

   • Material: Bronze
   • Nominal Diameter (DN): 65 mm
   • Connection type: Flanged DN65
   • Flanged Connections: The flanges allow easy assembly and disassembly from the piping system, also ensuring excellent sealing.

2. Shutter:

   • Material: Bronze or stainless steel, depending on the specific configuration.
   • Function: Controls the opening and closing of the flow.

3. Coil Solenoid:

   • Power: 70W
   • Year of Production: 2015
   • Material: Outer casing generally made of resin or heat-resistant plastic, with copper winding.
   • Function: Electrifies and magnetizes the core to move the shutter, opening or closing the valve.

4. Seals:

   • Materials: PTFE, EPDM or NBR, depending on the specific working conditions and the fluid used.
   • Function: They ensure the seal between the various moving and static parts.

5. Return Spring:

   • Material: Stainless steel or treated carbon steel.
   • Function: Allows return to the closed position when the coil is not powered.

Dimensions and Mechanical Specifications

• Nominal Diameter (DN): 65 mm
• Flange Outer Diameter: Approx. 185 mm (standard for DN65)
• Number of Holes for the Flange: 4 or 8, depending on the specific standard followed.
• Working Pressure:
  • Minimum: 0 bar (requires differential pressure to open)
  • Maximum: 10 bar
• Operating Temperature:
  • Range: -10°C to +80°C (depending on the fluid)
• Weight: Approximately 15-20 kg, variable based on specific configurations.

Mechanical Characteristics and Calculation Formulas

To determine the optimal parameters of use, the following formulas can be applied:

1. Flow rate (Q):

   • For an incompressible fluid such as water, the flow rate can be calculated using the continuity formula:
   $$Q$$

   Where:

   • AA $A$ is the cross-sectional area of ​​the pipe (m²)
   • vv $v$ is the velocity of the fluid (m/s)
   • dd $d$ is the internal diameter of the valve (m)

2. Pressure Drop (ΔP):

   • To estimate the pressure drop across the valve:
   $$\Delta$$

   Where:

   • KvK_v $K$ v ​is

3. Force Required to Open Valve (F):

   • The necessary force can be calculated as:
   $$F$$

   Where:

   • PP $P$ is the differential pressure across the valve (Pa)
   • AA $A$ is the shutter area (m²)

Workable Materials

DN65 bronze solenoid valve can work with the following materials:

• Water : Ideal for applications in water distribution systems.
• Oils : Compatible with non-corrosive mineral oils.
• Non-Corrosive Gases : Perfect for gases such as compressed air, nitrogen, and other non-corrosive technical gases.
• Steam : Can be used for low pressure steam, provided the temperature is within specified limits.

Maintenance

1. Visual Inspection:

   • Regularly check the integrity of the gaskets and flanges.
   • Check the solenoid coil for any signs of wear or damage.

2. Cleaning:

   • Remove debris and impurities from the valve body to avoid blockages.
   • Clean the coil and electrical connectors to ensure proper operation.

3. Periodic Tests:

   • Perform pressure tests to ensure the valve maintains leak-proof specifications.
   • Test the resistance of the solenoid coil to make sure it is working properly.

4. Lubrication:

   • Apply compatible lubricants to moving parts if necessary.

How to Evaluate a Good Used Car

To determine if your used solenoid valve is still in good condition:

1. Bronze State:

   • Make sure the valve body has no signs of corrosion or erosion.

2. Coil Operation:

   • Check that the solenoid coil works correctly, without voltage drops.

3. Seal Integrity:

   • Check that the seals are not hardened or damaged.

4. No Leaks:

   • Mount the valve in a test system and check that there are no leaks when opening and closing.

Sectors of Use

This solenoid valve is mainly used in:

• Chemical and Petrochemical Industry: For the control of non-corrosive fluids and gases.
• Food Industry: For applications requiring materials compatible with food contact.
• Water and Irrigation Systems: For the automated management of the water flow.
• HVAC systems: Used in heating, ventilation and air conditioning systems.

Why It's Better to Buy Used

Purchasing a used solenoid valve, especially if never used, as in the case of this Fantini DN65, can offer several advantages:

1. Reduced Cost: Purchasing a used component can significantly reduce costs while still maintaining high performance.
2. Immediate Availability: Usually, used components are ready to be installed, reducing waiting times for new production orders.
3. Reliability: A quality valve like this, made of bronze, has a long operating life and can continue to function perfectly for many years.

Conclusion: The Fantini DN65 solenoid valve is a high quality component, ideal for various industrial applications. Even when used, it can represent an excellent deal, offering a mix of reliability, durability and reduced costs.
