This is a Burkert direct operating 2/2 way solenoid valve with G 3/8 inch threads and a 110 V AC coil. The valve has a brass housing with stainless steel sealing and an orifice size of 4 mm. The circuit function of the solenoid valve is normally closed, which means the valve opens 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 0 – 12 bar (174 psi) and a maximum temperature of 130 °C (266 °F). The valve has a Kv-value of 0.5 m3/h, this translates to a flow rate of 8 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 1, which means 1 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. 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. Suitable for vacuum applications. The valve has an IP65 rating if properly connected.
Pros:
- Suitable for vacuum applications
- Good protection against the environment thanks to the IP65 rating
- Solenoid valves open and close very fast compared to many other valve types
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 0256 plunger solenoid valve can be utilized in a variety of applications. It is offered with either a brass or stainless steel body and is available with numerous orifice and connection options. The valve features a block screwed coil system and can accommodate applications up to DN 12, providing suitability for diverse applications with its wide range of capabilities.
