This is a Burkert indirect operating 2/2 way solenoid valve with a 24 V DC coil. The valve has a brass housing with FKM sealing and an orifice size of 10 mm. The circuit function of the solenoid valve is normally open, which means the valve closes when voltage is applied. The brass housing is durable, suitable for neutral fluids and resistant to many chemicals. 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. The valve is fat and oil free, meaning it won’t contaminate the media. Therefore, it’s suitable for laboratory use as well as oxygen. The valve has an IP65 rating if properly connected.
Pros:
- Oil and fat free, so the valve does not contaminate the medium
- Good protection against the environment thanks to the IP65 rating
- This valve is suitable for use with oxygen
- Type 6281 is ideal for larger flows
- Solenoid valves open and close very fast compared to many other valve types
- A damped design ensures reduced noise levels
- Low risk on water hammer, thanks to the dampened closing
Cons:
- Not suited for low pressure differentials (<0.2 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 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. A minimal pressure differential is always 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 offers various options, including different housing materials, ATEX versions, and a manual override feature.
Please note: this product is made to order and can unfortunately not be returned.
