Product Information

Full details

The Burkert 222031 is an indirectly operated, normally closed (NC) 2/2 way solenoid valve designed for controlling fluid flow. It is ideal for industrial applications requiring reliable and precise valve operation, particularly where a minimum differential pressure can be maintained. A key benefit is its robust stainless steel construction suitable for demanding environments. However, note that a DIN connector is not included with this model and must be purchased separately.

Extended Product Information

FAQs

What is the circuit function of this valve?

The circuit function is normally closed (NC), meaning the valve is closed when de-energized and opens when energized. The specific function is 'voltage = open'.

Is a DIN connector included with the valve?

No, the DIN connector is not included with the Burkert 222031 solenoid valve and must be purchased separately.

What is the maximum media temperature this valve can handle?

The valve is suitable for maximum media temperatures of 90 °C (194 °F).

What is the minimum pressure required for the valve to operate?

The valve is indirectly operated and requires a minimum differential pressure. The operating range is 0.2 to 16 bar (3 to 232 psi).

What type of seal does this valve use?

This valve features EPDM sealing, which offers good resistance to a range of chemicals and temperatures.

Can this valve be used with aggressive chemicals?

While stainless steel and EPDM offer good resistance, compatibility with specific aggressive chemicals should always be verified against material charts to ensure optimal performance and longevity.

What is the Kv-value of this valve?

The Kv-value is 30 m³/h, which corresponds to approximately 500.1 l/min at a differential pressure of 1 bar for water.

Troubleshooting

Valve does not open when energized

Check electrical connection and ensure correct voltage (230V AC) is applied. Verify that a minimum differential pressure is present across the valve. Ensure the DIN connector is properly seated and wired.

Valve leaks when closed

Inspect for debris on the valve seat. Ensure the differential pressure is sufficient to keep the valve closed. Check the condition of the EPDM seal for wear or damage.

Valve does not close when de-energized

Ensure electrical power is completely removed. Check for system pressure fluctuations or backpressure issues preventing closure. Inspect the internal components for obstructions.

Reduced flow rate

Verify the orifice (40 mm) is not blocked. Check system pressure and ensure it is within the operating range. Confirm the Kv-value (30 m³/h) is adequate for the application.

Pros and Cons

Pros

  • Durable stainless steel construction for longevity.
  • Suitable for a wide range of media temperatures.
  • High flow capacity due to the 40 mm orifice.
  • Reliable sealing with EPDM material.
  • Standard G 2 inch threads for easy installation.

Cons

  • Requires a minimum differential pressure to operate.
  • DIN connector is not included and must be sourced separately.
  • Not suitable for direct-acting applications.
  • EPDM sealing may not be suitable for all aggressive chemicals or extreme temperatures beyond its rating.

Setup, Compatibility & Care

Setup:

  1. Ensure the system pressure is within the 0.2 to 16 bar range and the media temperature is below 90 °C.
  2. Verify that the media is compatible with EPDM seals and stainless steel housing.
  3. Connect the valve to the G 2 inch pipe system, ensuring a secure and leak-free connection.
  4. Important: Connect the electrical coil using a suitable DIN connector (not included). Ensure correct voltage (230 V AC) and wiring to achieve normally closed operation (voltage = open).
  5. Ensure a minimum differential pressure is present for proper valve actuation.

Compatibility:

  • Electrical: Requires a 230 V AC power supply and a compatible DIN connector.
  • Mechanical: Compatible with G 2 inch threaded piping systems.
  • Media: Suitable for water, steam, and other neutral fluids. Check EPDM and stainless steel compatibility for specific media.

Care:

  • Regularly inspect the valve for any signs of external damage or leaks.
  • While the stainless steel is corrosion-resistant, avoid harsh cleaning chemicals that could damage the seals or external surfaces.
  • If the valve is removed for maintenance, ensure the system is depressurized and drained. Clean any debris from the valve seat before reinstallation.
