This is a Burkert indirect operating 2/2 way solenoid valve with 3/8 inch NPT threads and a 230 V AC/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 closed, which means the valve opens when voltage is applied. Suitable for a pressure of 0.5 – 10 bar (7 – 145 psi) and a maximum temperature of 90 °C (194 °F). The valve has a Kv-value of 1.9 m3/h, this translates to a flow rate of 32 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 2, which means 2 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 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. Thanks to the ATEX and IECEx certification, this solenoid valve is suited for explosive environments. The valve has an IP65 rating if properly connected.
Pros:
- ATEX-certified
- Good protection against the environment thanks to the IP65 rating
- Solenoid valves open and close very fast compared to many other valve types
- Compact design with high flow rate
- A damped design ensures reduced noise levels
- Low risk on water hammer, thanks to the dampened closing
Cons:
- Not suited for low pressure differentials (<0.5 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 6213 valve is a semi-direct operated valve. The plunger of the solenoid is coupled to the rubber membrane via a spring. The valve opens at zero bar but requires a minimal pressure differential for full opening. Orifices up DN 40 and port sizes up to 2 inch are available. All 6213 valves satisfy protection class IP65 and feature a damped housing design for quiet closing. The standard brass housing satisfies all European drinking water requirements. A special version (HP00) which opens the valve without differential pressure is available for gas and vacuum applications. For reduced energy requirement, all coils can be delivered with electronic power reduction.
Please note: this product is made to order and can unfortunately not be returned.
