Magnetic valves

Extremely fast and very precise control for water, steam and refrigerants.

Use an electronically controlled magnet to position the stem and metal disc plug to very quickly and precisely control flow and provide close-off.

Water and Steam

2-way and 3-way mixing valves range from ½- to 4-inch with Cv from 0.6 to 58. They have modulating control for hot or chilled water, and steam with media temperature ranging from 34 ̊ F to 356 ̊ F.

Refrigeration

Siemens magnetic actuated refrigeration 2-way and 3-way (mixing and diverting) valves are designed for modulating control of refrigeration circuits using most commonly used safety refrigerants as well as R744 (CO₂) and ammonia (MVS661 only) with a temperature range of -40° F to 250° F. Available in sizes from ½- to 1¼-inch with Cv from 0.12 to 14.
