Solenoid Valve G1/8'' NC Stainless Steel FKM -1-10bar/-15-145psi 24VDC 2871 236001
Reference: 236001
Brand: Burkert

Burkert 2/2 way solenoid valve (type 2871) with G 1/8 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 max media temperatures of 90 °C (194 °F) and a pressure range of -1 to 10 bar (-15 to 145 psi). Housing of stainless steel with FKM sealing and a 1 mm orifice. The Kv-value is 0.027 m3/h (0.45 l/min at dp = 1 bar water).
Note: DIN connector not included.

This is a Burkert direct operating 2/2 way solenoid valve with G 1/8 inch threads and a 24 V DC coil. The valve has a stainless steel housing with FKM sealing and an orifice size of 1 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 -1 to 10 bar (-15 to 145 psi) and a maximum temperature of 90 °C (194 °F). The valve has a Kv-value of 0.027 m3/h, this translates to a flow rate of 0 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 0.3, which means 0.3 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. The stainless steel housing is very durable, strong and resistant to a wide range of chemicals with the exception of chloride solutions. The FKM (fluorine rubber or Viton) sealing has excellent chemical properties, is suited for most oils and solvents but it cannot handle hot water or steam. 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 valve has an IP65 rating if properly connected.

Pros:

  • Good protection against the environment thanks to the IP65 rating
  • Solenoid valves open and close very fast compared to many other valve types
  • Compact valve design
  • Response time less than 15 ms

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 2871 is a direct-operated plunger solenoid valve. The 2871 valve serves primarily for proportional control, ideal for applications requiring continuous flow rate control. Depending on the model, the 2871 valve operates from 0 to a maximum of 12 bar, has a 1/8 inch port size (BSP and NPT) and can also be mounted on a sub-base. The orifice sizes ranging from 0.05 to 2.0 mm. For larger flow rates type 2873 or 2875 provide a solution. The flow can be controlled using a digital controller (for example the Bürkert 8605 or 8611 types). Please note that the correct sizing of the valve (Kv) is critical in flow control setups. If uncertain about choosing the appropriate valve or whether the 2871 valve suits your needs, read our article on proportional solenoid valves or contact our technical support.
