2/2-way solenoid valve, normally open, G 1", DN 27.5 mm, 216 l/min, 24 V AC, stainless steel 1.4581

This normally open 2/2-way solenoid valve keeps the line clear without control voltage and is energised only to shut it off. That saves energy in circuits which carry flow most of the time. At the G 1" port with a nominal width of 27.5 mm the valve reaches a Kv value of 216 l/min. A 1.4581 stainless steel body, 1.4104 internals and an FKM seal allow an operating pressure of 0 to 16 bar at medium temperatures of 0 to +80 °C. Power consumption is 26 VA at 24 V AC.

Benefits

• Kv value of 216 l/min at the G 1" port with a nominal width of 27.5 mm
• Normally open function energises the coil with 24 V AC only for closing
• 1.4581 stainless steel body, 1.4104 internals and an FKM seal
• Operating pressure of 0 to 16 bar and medium temperatures of 0 to +80 °C
• Protection class IP 65 at a power consumption of 26 VA
• The normally open version can also be installed with a horizontal solenoid

Applications

• Cooling water circuits with high volume flow that remain open during normal operation
• Service and process water lines up to 16 bar with a G 1" connection
• Bypass lines that are closed only for switchover
• Systems with a 24 V AC control circuit needing a Kv value of 216 l/min

Standards and conformity

Coil and device plug together with the valve body provide protection class IP 65. The 24 V AC control voltage may vary by ± 10 percent.
