Solenoid Valve G1/2'' NC Stainless Steel EPDM -1-2bar/-15-29psi 24VDC Oxygen Fat/Oil Free 2875 247164

Solenoid Valve G1/2'' NC Stainless Steel EPDM -1-2bar/-15-29psi 24VDC Oxygen Fat/Oil Free 2875 247164
Reference: 247164
Brand: Burkert

Burkert 2/2 way solenoid valve (type 2875) with G 1/2 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 2 bar (-15 to 29 psi). Housing of stainless steel with EPDM sealing and a 8 mm orifice. The Kv-value is 1.1 m3/h (18.34 l/min at dp = 1 bar water). The valve is fat and oil free.
Note: DIN connector not included.

This is a Burkert direct operating 2/2 way solenoid valve with G 1/2 inch threads and a 24 V DC coil. The valve has a stainless steel housing with EPDM sealing and an orifice size of 8 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 2 bar (-15 to 29 psi) and a maximum temperature of 90 °C (194 °F). The valve has a Kv-value of 1.1 m3/h, this translates to a flow rate of 18 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 1, which means 1 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 EPDM (ethylene propylene diene monomer rubber) sealing is suited for neutral fluids and many chemicals, but it has poor resistance to oils and fats. 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 is fat and oil free, meaning it won't contaminate the media. Therefore, it's suitable for laboratory use as well as oxygen. The valve has an IP65 rating if properly connected.

Pros:

  • Oil and fat free, so the valve does not contaminate the medium
  • Good protection against the environment thanks to the IP65 rating
  • Silicone free, so the valve does not contaminate the medium
  • Compact valve design
  • Response time less than 25 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 2875 is a direct operated plunger solenoid valve and is primarily used for applications where flow rate control is necessary (proportional control). The valve works from 0 to 25 bar and has a 3/8 inch or 1/2 inch port size (BSP or NPT). The orifice sizes ranging from 2 to 9.5 mm. For smaller flow rates, types 2871 and 2873 provide a solution. The flow can be controlled using a digital controller (for example the Bürkert 8605 or 8611 types). Explosion-protected coils are optional. Please note that the correct sizing of the valve (Kv) is critical in flow control setups. For advice on which valve to choose and if the 2875 valve is right for you, please read our article about proportional solenoid valves or contact our technical support.
