Description

Bürkert direct operating 2/2-way solenoid valve with G1/2'' inner threads and 12V 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 6 mm. The circuit function of the solenoid valve is normally closed, which means the valve opens when voltage is applied. 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.

Important advantages

  • Frictionless design with excellent adjustment characteristic for proportional control
  • Suited for demanding applications (i.e. dry gases, high control range etc)
  • Bürkert design: proven reliability & durability

2875 series

The Bürkert 2875 is a direct operated plunjer solenoid valve and is primarly used for applications where flow rate control is necessary (proportional control). The valve works from 0 to 25 bar and has a 3/8" or 1/2" port size (BSP or NPT). The orifice sizes ranges 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.

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