Bürkert 2/2-way solenoid valve (type 2873) with G1/4'' threads and a 24V DC coil. Designed for proportional flow control. Normally closed (voltage = open) and direct operating, so no differential pressure required. For media with max 90°C at a differential pressure of 0-8 bar. Housing of brass with FKM sealing and a 2 mm orifice. The Kv-value is 0.1 m3/h (1.67 l/min at dp=1 bar water).

Bürkert direct operating 2/2-way solenoid valve with G1/4'' inner threads and 24V DC (direct current) coil. Designed for proportional flow control through a PWM signal. The duty cycle of the signal determines the coil current, which directly correlates to the plunger position. Optionally, the valve can also be driven with DC voltage. The valve has a brass housing with FKM sealing and an orifice size of 2 mm. The circuit function of the solenoid valve is normally closed, which means the valve opens when voltage is applied. Suitable for systems with a differential pressure of 0-8 bar and a maximum temperature of 90°C. The valve has a Kv-value of 0.1 m3/h, this translates to a flow rate of 1.67 l/min at the differential pressure of 1 bar (for water). The brass housing is durable, suitable for neutral fluids and resistant to many chemicals. 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 can be proportionally controlled by using a digital controller such as, for example, the Bürkert 8605 or 8611 types. Energy efficient design for a long product lifecycle. The valve has an IP65 rating if properly connected.

Important advantages

  • Energy-saving design which ensures a low heating of the medium and, in addition, a long service life
  • Good protection against the environment thanks to the IP65 rating
  • This valve is suitable for use with oxygen
  • Designed for proportional control with excellent adjustment characteristic
  • Very compact design
  • Bürkert design: proven reliability & durability

2873 series

The Bürkert 2873 is a direct-operated plunger solenoid valve and is primarly used for applications where flow rate control is necessary (proportional control). Depending on the model, the valve works from 0 up to 16 bar and has a 1/8" or 1/4" port size with BSPP or NPT thread or can be mounted on sub-base flange. The orifice sizes ranges from 0.8 to 6 mm. 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. For smaller flow rates, type 2871 provides a solution. For larger flow rates, please consider 2875. For advice on which valve to choose and if the 2873 valve is right for you, please read our article about proportional solenoid valves or contact our technical support.

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