Brand: Burkert

Burkert 2/2 way solenoid valve (type 0121) with G 3/8 inch threads and a 24 V DC coil. The circuit function of the solenoid valve is normally closed (voltage = open). The valve is direct operating, so no differential pressure required. Suitable for slightly contaminated and aggressive media (media separation). Suitable for max media temperatures of 70 °C (158 °F) and a pressure range of 0 to 2 bar (29 psi). Housing of plastic with FFKM sealing and a 4 mm orifice. The Kv-value is 0.3 m3/h (5.0 l/min at dp = 1 bar water). Manual override feature.
Note: DIN connector not included.

Description

This is a Burkert direct operating 2/2 way solenoid valve with G 3/8 inch threads and a 24 V DC coil. The valve has a plastic housing with FFKM sealing and an orifice size of 4 mm. The circuit function of the solenoid valve is normally closed, which means the valve opens when voltage is applied. As it is direct operating, no pressure differential over the valve is needed to open the valve. Suitable for a pressure range of 0 to 2 bar (29 psi) and a maximum temperature of 70 °C (158 °F). The valve has a Kv-value of 0.3 m3/h, this translates to a flow rate of 5 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 0.35, which means 0.35 GPM @ 1 psi pressure drop. For many applications it is enough to select a valve based on the thread size and orifice diameter. For more accurate sizing, use the Kv-value with our easy to use valve sizing calculator. This model is media separated. This means that the working parts such as the spring are separated from the media by a flexible membrane, which makes it possible to use of slightly contaminated and aggressive media. The FFKM (perfluorinated rubber) sealing has excellent chemical properties, better than FKM and similar to PTFE. Please note that the internal valve parts, such as the stainless steel plunger and springs, are also in contact with the medium and must be chemically compatible. Consult our chemical resistance chart to verify compatibility of housing and seals with the medium. The manual override feature can be used to commission the system. The valve has an IP65 rating if properly connected.

Pros:

  • Aggressive media are possible thanks to the media separated design
  • The manual override is ideal for commissioning and in case of power outage
  • Good protection against the environment thanks to the IP65 rating
  • Solenoid valves open and close very fast compared to many other valve types

Cons:

  • Solenoid valves are very sensitive to dirt and can only be used with clean liquids and gases
  • The coil may get hot when energized. A well ventilated environment is recommended
  • DIN connector not included

Series:

The Bürkert type 0121 valve is a direct-operated, media separated pivoted armature valve with a stainless steel (316L), PTFE (teflon), PVC (polyvinyl chloride), PP (polypropylene) or PVDF (polyvinylidene fluoride) housing. The valve is available in 3/2- and 2/2-way versions. As a 3/2-way version, it can be delivered as a normally open, normally closed, distributing or mixing valve. The valve can be delivered with a diameter from DN 2 up to DN 8. Depending on the model, the valve can operate up to 6 bar. All 0121 valves come with a manual override for commissioning and testing. ATEX-approved versions are also available.

Please note: this product is made to order and can unfortunately not be returned.
