SAACKE ESVN 12 | Electromagnetic Safety Shut-Off Valve

🔥 Product Introduction

The SAACKE ESVN 12 is an electromagnetic safety shut-off valve designed for burner fuel systems. SAACKE’s current conformity documentation specifically lists ESVN 12 among its safety shut-off valves for oil burners.

The ESVN 12 is suitable for fuel-oil burner applications where the fuel supply must be electrically controlled and safely interrupted. Available technical information for the ESV 12 family specifies a 230 V, 40–60 Hz nominal supply, 5 bar operating pressure, IP65 protection, and a 98 V DC holding voltage.

The supplied listing identifies the unit as SAACKE ESVN 12, used condition, runner takeout, with Germany listed as the country of origin.

⚙️ Operating Guidelines

🔹 Verify the complete valve designation before installation.

🔹 Confirm that the fuel type, pressure, temperature, connection size, and electrical supply match the existing burner system.

🔹 Inspect the valve body, coil, terminal box, rectifier, sight indicator, seals, and pipe connections.

🔹 Make sure the fuel line is depressurized before removing or installing the valve.

🔹 Install the valve in the correct flow direction.

🔹 Keep the fuel system clean and prevent dirt or foreign material from entering the valve.

🔹 Check electrical insulation and grounding before energizing.

🔹 Never bypass a burner safety shut-off valve during normal operation.

 

🛠️ How to Use

1. 🔍 Verify the ESVN 12 nameplate and technical ratings.
2. 🧰 Confirm that the burner and fuel system are shut down.
3. ⛔ Isolate the fuel supply and release pressure safely.
4. 🔧 Install the valve according to the specified flow direction.
5. 🔌 Connect the electrical circuit according to the original burner-control wiring.
6. ⚡ Verify the supply voltage before energizing.
7. 🧪 Check for fuel leakage.
8. 🔥 Start the burner using the normal burner-control sequence.
9. 👀 Confirm that the valve opens and closes correctly.
10. ✅ Perform a safety shut-off test before returning the burner to normal service.

 

🔌 Power-On Sequence

1. 🔍 Inspect the complete fuel valve assembly.
2. ⛽ Confirm that the fuel system is correctly connected and leak-free.
3. 🔌 Check the electrical wiring and grounding.
4. ⚡ Energize the burner control system.
5. 🧠 Allow the burner-management system to complete its safety checks.
6. 🔋 Apply the specified valve control voltage.
7. 👀 Confirm correct valve operation.
8. 🔥 Proceed with burner ignition only after the safety sequence is satisfied.

 

⛔ Power-Off Sequence

1. Stop the burner through the normal burner-control sequence.
2. Confirm that the fuel valve closes.
3. Verify that fuel flow has stopped.
4. If maintenance is required, isolate the electrical supply.
5. Isolate the fuel supply and depressurize the relevant section.
6. Allow hot components and fuel lines to cool before servicing.
7. Do not manually force the valve open during a safety shutdown.

⚠️ This is a fuel-system safety component. Testing and maintenance should be performed by qualified personnel familiar with burner-management and fuel-system safety procedures.

 

📘 Product Usage Notes

The ESVN 12 is not simply a general-purpose solenoid valve. SAACKE identifies the ESVN 12 specifically within its safety shut-off valve range for oil burners.

A documented ESV 12 configuration shows a 230 V, 40–60 Hz nominal supply, 5 bar operating pressure, 98 V DC holding voltage, IP65 protection, and a maximum medium temperature of 140°C. It also specifies a rectifier and a 100% duty-cycle coil arrangement.

For replacement work, do not select the valve by appearance alone. Match the model, identification number, coil specification, connection arrangement, fuel type, pressure rating, and burner application.
