Herion 3/2-way solenoid valve NPT 1/4, normally open, without coil, direct acting poppet, 0 to 10 bar - Norgren 1025254000000000

The 1025254000000000 is a direct solenoid actuated poppet valve from the Norgren Herion range, built as a 3/2-way valve (normally open) with a NPT 1/4 port. In the pressure range of 0 to 10 bar the 1025254000000000 reaches a flow rate of 340 l/min. The 1025254000000000 is supplied without a solenoid coil, which is selected separately to suit the control voltage. The 1025254000000000 is actuated by a direct solenoid with spring return. The body of the 1025254000000000 is made of anodised aluminium, seals are NBR. For safety applications Norgren rates the 1025254000000000 up to SIL 3. The permissible ambient temperature of the 1025254000000000 ranges from -25 to 80 °C.
