Solenoid Valve G1/2'' NO Stainless steel PCTFE 1-200bar/15-2901psi 24VAC 6240 323485
Burkert 2/2 way solenoid valve (type 6240) with G 1/2 inch threads and a 24 V AC coil. The circuit function of the solenoid valve is normally open (voltage = close). The valve is indirect operating, so a small differential pressure required. Suitable for max media temperatures of 80 °C (176 °F) and a pressure range of 1 - 200 bar (15 - 2901 psi). Housing of stainless steel with PCTFE sealing and a 12 mm orifice. The Kv-value is 2.2 m3/h (36.67 l/min at dp = 1 bar water).
Note: DIN connector is included.

Description
This is a Burkert indirect operating 2/2 way solenoid valve with G 1/2 inch threads and a 24 V AC coil. The valve has a stainless steel housing with PCTFE sealing and an orifice size of 12 mm. The circuit function of the solenoid valve is normally open, which means the valve closes when voltage is applied. Suitable for a pressure of 1 - 200 bar (15 - 2901 psi) and a maximum temperature of 80 °C (176 °F). The valve has a Kv-value of 2.2 m3/h, this translates to a flow rate of 37 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 3, which means 3 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 PCTFE (Polychlorotrifluoroethylene) sealing is resistant to almost all media. 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
- More reliable and durable thanks to the piston design instead of a rubber membrane
- Solenoid valves open and close very fast compared to many other valve types
Cons:
- Not suited for low pressure differentials (< 1 bar). In case of low pressure or a vacuum, consider a (semi-)direct solenoid valve
- 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 valve type 6240 is a 2/2-way semi-direct operated solenoid valve with a compact design and internal orifice diameters of up to DN 13. The special fluidic form of the valve body allows for high flow rates, and the semi-direct operation enables suitability for applications with zero differential pressure in the system. Semi-direct operation is also referred to as servo assisted operation. The 6240 makes use of a piston instead of the typical rubber membrane, which makes the valve suitable for more demanding circumstances. The spring coupling of the pilot valve to the piston of the main valve allows for gentle opening and closing of the valve, which provides for a long service life. This 2/2-way piston valve includes a variety of certifications and a diverse range of tested body and seal materials. The type 6240 works in various applications, including specialty versions for low temperatures (-30°C), high-pressure, explosion protection, and steam.
