Solenoid Valve 20x20 mm SFB flange NC Brass FKM 0-34bar/493psi 24VAC ATEX 7011 20025290
Notice: This product is discontinued
Burkert 2/2 way solenoid valve (type 7011) with 20x20 mm SFB flange and a 24 V AC 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 100 °C (212 °F) and a pressure range of 0 - 34 bar (493 psi). Housing of brass with FKM sealing and a 1.2 mm orifice. The Kv-value is 0.045 m3/h (0.75 l/min at dp = 1 bar water). This solenoid valve is ATEX and IECEx certified.
Note: DIN connector not included.

Description
This is a Burkert direct operating 2/2 way solenoid valve with 20x20 mm SFB flange and a 24 V AC coil. The valve has a brass housing with FKM sealing and an orifice size of 1.2 mm. SFB is a Burkert specific flange design that enables compact mounting of multiple valves on a manifold. 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 of 0 - 34 bar (493 psi) and a maximum temperature of 100 °C (212 °F). The valve has a Kv-value of 0.045 m3/h, this translates to a flow rate of 1 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 0, which means 0 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 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. Thanks to the ATEX and IECEx certification, this solenoid valve is suited for explosive environments. The valve has an IP65 rating if properly connected.
Pros:
- ATEX-certified
- Good protection against the environment thanks to the IP65 rating
- Solenoid valves open and close very fast compared to many other valve types
- SFB flange design enables compact mounting of multiple valves on a manifold
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
Series:
The Bürkert type 7011 is a versatile direct-acting plunger valve that can be used in a variety of applications. Its welded stopper and core guide tube enhance pressure resistance and guarantee leak-tightness. The valve is customizable with different housing and seal materials to meet specific needs. The valve's flange variant (SFB) allows for space-efficient arrangement on a multiple manifold, and it also includes DVGW EN 161 and explosion-proof variants. Flexible hose connections can be made using push-in fittings. When combined with a plug conforming to DIN EN 175301-803 shape B, the valves offer IP65 protection. The type 7011 valve is ideal for small valves up to DN 2.4 due to its compact design and slipped-over coil system. This valve can be easily mounted on a flange or manifold, making it convenient for various systems. Additionally, explosion-proof variants are available for safety requirements.
