3/2-way solenoid valve, normally open (NO), G 1/8", DN 2.5 mm, 24 V DC, brass body

For media circuits that have to stay open at rest, this 3/2-way solenoid valve is supplied in the normally open version. Only when the coil is energised with 24 V DC does the valve close the inlet and vent the consumer through the G 1/8" male exhaust port. A nominal width of DN 2.5 mm gives a Kv value of 3.4 l/min at an operating pressure of 0 to 7 bar. The brass housing, internal parts in brass and stainless steel and an FKM seal allow media temperatures from -10 to +130 °C, while the ambient temperature must not exceed +50 °C. Overall length is 40 mm.

Benefits

• Nominal width DN 2.5 mm with a Kv value of 3.4 l/min
• Media temperature up to +130 °C thanks to the FKM seal and brass body
• Internal parts in brass and stainless steel for water, heating oil and neutral gases
• Operates from 0 bar upwards, so no minimum pressure is required
• IP 65 protection with a size 3 connector and a voltage tolerance of ± 10 %
• Compact overall length of 40 mm with G 1/8" port thread

Applications

• Shutting off hot water lines in heating and cleaning systems
• Switching heating oil circuits on burners with 24 V DC control
• Safety-related circuits that must remain open when power fails
• Dosing stations for neutral low-viscosity media up to 7 bar
• Test rigs with small flow rates around a Kv value of 3.4 l/min

Standards and conformity

The IP 65 rating is achieved with the coil and a size 3 connector fitted. The permissible control voltage tolerance is ± 10 % referred to 24 V DC. Installation is carried out with the coil upright.
