G1/2'' Stainless Steel 24VUC ATEX Solenoid Valve 6281 277545
Notice: This product is discontinued and replaced by 349707
Bürkert 2/2-way solenoid valve (type 6281) with G1/2'' threads and a 24V UC coil. Normally closed (voltage = open) and indirect operating, so a small differential pressure required. For media with max 90°C at a differential pressure of 0.2-16 bar. Housing of stainless steel with FKM sealing and a 13 mm orifice. The Kv-value is 3.8 m3/h (63.33 l/min at dp=1 bar water). Low risk of water hammer thanks to dampened closing. Certified up to ATEX zone 1.

Description
Bürkert indirect operating 2/2-way solenoid valve with G1/2'' inner threads and 24V UC (alternating or direct current) coil. The valve has a stainless steel housing with FKM sealing and an orifice size of 13 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 0.2-16 bar and a maximum temperature of 90°C. The valve has a Kv-value of 3.8 m3/h, this translates to a flow rate of 63.33 l/min at the differential pressure of 1 bar (for water). The stainless steel housing is very durable, strong and resistant to a wide range of chemicals with the exception of chloride solutions. 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. The valve's design prevents water hammering. 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.
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
- The risk of water hammer is low, thanks to the dampened closing
- Good protection against the environment thanks to the IP65 rating
- Type 6281 is ideal for the control of larger flows
- Bürkert design: proven reliability & durability
6281 series
The Bürkert 6281 valve is an indirect operated solenoid valve of the S.EV series. To open and close, the valve features a large flexible rubber membrane. The pressure difference over the inlet and outlet ports is used to move the membrane up and down. Therefore, always a minimal pressure differential is required. Thanks to the special design of the membrane and valve seat, the valve operates quietly. The brass housing satisfies all European drinking water requirements. The 6281 series is available with a wide variety of options, such as other housing materials, ATEX versions and a manual override feature.
