Solenoid Valve 40mm Flange NC Cast iron EPDM 0-12bar/174psi 230VAC Vacuum 73649

This is a Burkert semi-direct operating 2/2 way solenoid valve with 40 mm flange and a 230 V AC coil. The valve has a cast iron housing with EPDM sealing and an orifice size of 40 mm. The circuit function of the solenoid valve is normally closed, which means the valve opens when voltage is applied. As it is semi-direct operating, no pressure differential over the valve is needed to open the valve. Suitable for a pressure range of 0 to 12 bar (174 psi) and a maximum temperature of 120 °C (248 °F). The valve has a Kv-value of 16 m3/h, this translates to a flow rate of 267 l/min at a differential pressure of 1 bar (for water). In imperial units: Cv = 18, which means 18 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 cast iron housing is suited for neutral fluids. The EPDM (ethylene propylene diene monomer rubber) sealing is suited for neutral fluids and many chemicals, but it has poor resistance to oils and fats. 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
• DIN connector not included
