Magnetic Valve and Actuator Combinations
Magnetic Valve and Actuator Combinations
FEATURE | FUNCTION | BENEFIT |
|---|
Fast positioning time (< two seconds), high-resolution stroke (1000:1) | Extremely fast and accurate positioning | Unrivaled performance in HVAC control – suitable for light industrial process control and extremely fast closed loop control |
Linear or equal-percentage valve characteristic | User selectable flow characteristic | Usable in all control systems, water or steam - multi-use product reduces inventory requirements |
Switch-selectable control signal: 0 to 10 Vdc, 2 to 10 Vdc, or 4 to 20 mA | User selectable input signal | Usable with all standard control signals – multi-use product reduces inventory requirements |
Position feedback with wear-free inductive stroke measurement | More durable than typical potentiometer type position measurement | Long life and consistent accurate feedback signal |
Low friction, robust, no maintenance required | Very few moving parts and very little contact | Long service life and low labor costs |
Fail-safe feature: A → AB closed when de-energized | Provides positive plug placement in event of power failure | Provides coil freeze protection when piped B -> AB Provides safety shut off of steam when piped A -> AB |
Manual override | Manually position valve in case of power loss | Assures process operation in case of power failure Eliminates need for additional manual bypass process piping Eases commissioning |
UL, cUL873 Listed, approved for plenum space installation | Meets North American agency approval standards | Assurance that products meet North American safety standards |
Fast Positioning
Reduction in the level of control loop difficulty
Fast stabilization of disturbance variables
Instant response to set point changes
Utilization of complex control algorithms
Easy commissioning and monitoring
Enhanced operational reliability
How do magnetic valves work?
Input voltage provides the magnetic force
Magnetic force provides the valve stroke
Infinite Stroke Resolution
Accurate flow control, even in the smallest control increments
Highest control quality, even without parallel connection of two control valves
Application with the prevision class of <1°C possible
More tolerant to over-sizing
Proportional control response throughout the positioning range, independent of coil characteristic
