Description
The 2/2-way solenoid valve MVA.1.MS.24A.N.RZ.25 controls fluids in plants via an electrical signal at 24 V AC. It operates in the range 0 to 12 bar at nominal size DN 25 and is force pilot operated.
Benefits
- Fail-safe NC position: without 24 V AC on the coil the flow path stays closed.
- Force pilot operated from 0 bar: switches without minimum pressure up to 12 bar at DN 25.
- Internal parts in brass and stainless steel, housing in brass and seat in brass and stainless steel, DN 25.
- NBR seal material for media from -20 to 85 °C at 0 to 12 bar.
- Connection for 24 V AC: connector socket, industrial standard type A, EN 175301-803-A, degree of protection IP 65 (with connector socket fitted), type MVA.1.MS.24A.N.RZ.25.
Applications
It is used in plant engineering, process technology and filling systems. The ambient temperature may be -10 to 50 °C, the medium -20 to 85 °C. Choose the NC version MVA.1.MS.24A.N.RZ.25 if the system must shut off safely when power fails.
