Description
The 2/2-way solenoid valve MVA.14.MS.12.N.RD.4 controls fluids in plants via an electrical signal at 12 V DC. It operates in the range 0 to 8 bar at nominal size DN 4 and is directly operated.
Benefits
- Fail-safe NC position: without 12 V DC on the coil the flow path stays closed.
- Directly operated: opens even without pressure, rated for 0 to 8 bar at DN 4.
- Internal parts in brass and stainless steel, housing in brass and seat in brass and stainless steel, DN 4.
- NBR seals: rated for medium temperatures of -20 to 85 °C, coil 12 V DC.
- Connection for 12 V DC: connector socket acc. to DIN EN 175301-803 standard type A, degree of protection IP 65 (with connector socket fitted), type MVA.14.MS.12.N.RD.4.
Applications
It is used in plant engineering, process technology and filling systems. Medium temperatures of -20 to 85 °C are permitted at an ambient of -20 to 55 °C. Driven at 12 V DC, it suits controls that have to shut off on power failure.
