Solenoid Valve 3/2-Way 20x20 mm SFB flange NO Brass FKM 0-6bar/87psi 24VDC 7012 20014039
Burkert 3/2 way solenoid valve (type 7012) with 20x20 mm SFB flange and a 24 V DC coil. The circuit function of the solenoid valve is normally open (voltage = close). 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 - 6 bar (87 psi). Housing of brass with FKM sealing and a 1.6 mm orifice. The Kv-value is 0.06 m3/h (1.0 l/min at dp = 1 bar water).
Note: DIN connector not included.

Description
This is a Burkert direct operating 3/2 way solenoid valve with 20x20 mm SFB flange and a 24 V DC coil. The valve has a brass housing with FKM sealing and an orifice size of 1.6 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 open, which means the valve closes when voltage is applied. When the valve is closed, the output port connects to a third exhaust port. As it is direct operating, no pressure differential over the valve is needed to open the valve. Suitable for a pressure of 0 - 6 bar (87 psi) and a maximum temperature of 100 °C (212 °F). The valve has a Kv-value of 0.06 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. 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
- 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 7012 valve is a plunger valve that operates directly. The stopper and core guide tube are welded together to enhance its ability to resist pressure and prevent leakage. The valve comes with various housing and seal materials that are suitable for different applications. Bürkert has a special flange variant called SFB that allows for space-saving installation of valves on a multiple manifold. The valve range also includes explosion-proof versions. For a flexible hose connection, users can choose push-in fittings. The ideal solution for direct mounting on a pneumatic actuator is a banjo fitting with a banjo bolt. There is an optional manual override for quick start-up and optimal maintenance. The valves meet IP65 protection requirements with a plug conforming to industry standard shape B or DIN EN 17301-803 shape C. The valves are well-protected against dust and water ingress, suitable for harsh and challenging environments. The plug also provides a secure and reliable connection, ensuring that the valve operates safely and efficiently. With this feature, users can have peace of mind knowing that their valves are protected and will perform reliably over an extended period of time.
