Magnetic valves

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.

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.
