Comoso Controlled Motion Solutions

Solenoid valves are typically operated by an on/off coil that remains on, generates heat, and consumes power while operating. Power consumption can be a problem for continuous duty applications. Parker Fluid Control Division offers a no power solution for your nonsafety shut-off applications. This solution is the Magnelatch® coil option. This coil option is offered on the products in this section. The Magnelatch® operator contains a permanent magnet that is shifted on (latched) or off (released) by a momentary electrical current pulse of approximately twenty milliseconds (.02 seconds). The conventional solenoid valve is in one of two positions – off or de-energized, or on – energized. The Magnelatch® requires no continuous power thus the term latch position is used for on and release position for off. Valves with Magnelatch coils remain in their last energized position and do not return to their de-energized position in the event of a power outage. Magnelatch coils are not available on valves for steam service. Valves with Magnelatch coils have the same pressure rating as that valve with a 10 watt coil.

Applications:

• Instrumentation
  
• No heat build up – eliminates constant calibrations and permits confinement and compactness. Can be used with such sensors as thermistors and thermocouples.
• Machine Tools
  
• Operates with simple switches and eliminates holding relays and relayed circuitry required to sequence and position operations.
• Remote Control Equipment
  
• pulsing circuitry, low power consumption permit the use of Magnelatch® coils in many custom operations. Operation can be controlled by radio frequency or mechanical timer, etc.
• Other Applications
  
• Medical equipment
• Transportation products
• Material handling equipment
• Solar panels
• Pilot valve on control valve (3-Way)
• Single acting Cylinder Actuation (3-way)
• Natural gas service
