Magnetic valves

Water and Steam Magnetic Valve — Find a Partner

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 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.

Features and benefits

Selectable flow characteristic

DIP switch selectable between equal percentage or linear.
Linear characteristic is optimized in the small opening range to eliminate problems from sudden increase of flow when the valve opens.

Position control and position feedback signal

Valve position is measured continuously so disturbances in the system are rapidly corrected.
Internal positioning controller ensures that the positioning signal and valve stroke are exactly proportional and delivers the position feedback signal.

Extremely fast positioning speed

< 2 second full stroke run time
Improves control-loop response time and stability

Very precise control

1000:1 resolution/rangeability
Resolution of most actuators is ≤ 100:1

When a building or space requires fast, precise control and zero valve down time, these Modulating Magnetic Valves deliver. Accuracy is unmatched, particularly in low-flow ranges. This means energy savings. These valves really excel in environments where climate consistency is critical.
