Solenoid Valve UNF 1/4-28 NO PEEK FFKM -1-2bar/-15-29psi 24VDC 6724 292443
Notice: This product is discontinued and replaced by 20071054
Burkert 2/2 way solenoid valve (type 6724) with UNF 1/4-28 threads 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 slightly contaminated and aggressive media (media separation). Suitable for max media temperatures of 50 °C (122 °F) and a pressure range of -1 - 2 bar (-15 - 29 psi). Housing of PEEK with FFKM sealing and a 1.2 mm orifice. The Kv-value is 0.026 m3/h (0.43 l/min at dp = 1 bar water).
Note: DIN connector not included.

Description
This is a Burkert direct operating 2/2 way solenoid valve with UNF 1/4-28 threads and a 24 V DC coil. The valve has a PEEK housing with FFKM sealing and an orifice size of 1.2 mm. The circuit function of the solenoid valve is normally open, which means the valve closes 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 -1 - 2 bar (-15 - 29 psi) and a maximum temperature of 50 °C (122 °F). The valve has a Kv-value of 0.026 m3/h, this translates to a flow rate of 0 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. This model is media separated. This means that the working parts such as the spring are separated from the media by a flexible membrane, which makes it possible to use of slightly contaminated and aggressive media. The FFKM (perfluorinated rubber) sealing has excellent chemical properties, better than FKM and similar to PTFE. 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 IP10 rating if properly connected.
Pros:
- Aggressive media are possible thanks to the media separated design
- Good protection against the environment thanks to the IP10 rating
- Solenoid valves open and close very fast compared to many other valve types
- Compact design with 8.9 mm installation width
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 6724 is a solenoid valve designed to meet the specific requirements of fluidic processes in various applications. In fields such as medical devices, printing, and pipetting, solenoid valves need to be small, lightweight, and capable of switching silently. The Whisper Valve Type 6724 is ideal for these applications due to its compact design, high chemical resistance, and almost silent switching (less than 20 dB(A)) with very low power consumption. The valve is highly versatile due to its modular structure and range of available material variants. Additionally, it offers high back-pressure tightness, excellent cleanability, and a 100% duty cycle. This valve is offered in two sizes, DN 0.8 mm (for vacuum pressures up to 5 bar) and 1.2 mm (for vacuum pressures up to 3 bar).
