G3/8'' Brass 24VUC ATEX Solenoid Valve 6240 278715

Bürkert semi-direct operating 2/2-way solenoid valve with G3/8'' inner threads and 24V UC (alternating or direct current) coil. The valve has a brass housing with PTFE 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. Suitable for systems with a differential pressure of 0-16 bar and a maximum temperature of 180°C. The valve has a Kv-value of 0.6 m3/h, this translates to a flow rate of 10 l/min at the differential pressure of 1 bar (for water). The brass housing is durable, suitable for neutral fluids and resistant to many chemicals. The PTFE (polytetrafluoroethene or teflon) 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. Energy efficient design for a long product lifecycle. The valve is certified for ATEX Ex-Zone 1, so it can be used in potentially explosive environments requiring this certification. The valve has an IP65 rating if properly connected. Suitable for cold media with temperatures from -40°C.

Important advantages

• ATEX certified up to Ex-Zone 1
• Energy-saving design which ensures a low heating of the medium and, in addition, a long service life
• Good protection against the environment thanks to the IP65 rating
• The durable piston design allows the use in even more demanding applications compared to rubber membrane solenoid valves
• The special fluidic form of the valve body allows for high flow rates
• Bürkert design: proven reliability & durability

6240 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 while the semi-direct operation makes it suitable for applications where zero differential pressure occurs 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. This, along with specialty versions such as low temperatures (-30°C), high-pressure, explosion protection and steam, allow for employment of the type 6240 in various applications.
