Description
The 2/2-way solenoid valve MVB.14.MS.24V.N.BD.4.EX controls fluids in plants via an electrical signal at 24 V AC/DC. It operates in the range 0 to 5 bar at nominal size DN 4 and is directly operated.
Benefits
- Open at rest: the valve only closes once 24 V AC/DC is applied to the coil, DN 4.
- ATEX version according to the manufacturer, observe the marking on the device for conditions of use.
- Switches from 0 bar: directly operated, no minimum pressure needed, operating pressure up to 5 bar.
- Internal parts in brass, housing in brass and seat in brass, DN 4.
- NBR seals: rated for medium temperatures of 0 to 80 °C, coil 24 V AC/DC.
- Connection for 24 V AC/DC: cable, 3 m, degree of protection IP 65 (with connector socket fitted), type MVB.14.MS.24V.N.BD.4.EX.
Applications
Because the coil system is separated from the medium by a diaphragm, the manufacturer rates the series for critical media as well. Check the resistance of housing and seal to the specific medium beforehand. The ambient temperature may be 0 to 55 °C, the medium 0 to 80 °C. Driven at 24 V AC/DC, it suits circuits that have to stay open on power failure.
