Siemens Introduces the MVL702 Magnetic Expansion Valve

Key Features of the MVL702 Magnetic Expansion Valve:

1. Exceptional Energy Efficiency:

   • Transitions from closed to fully open in just one second, making it the fastest valve on the market.
   • Ensures higher system stability and energy efficiency, with potential heating capacity increases of up to 21% compared to traditional stepper valve technology.
   • End customers can benefit from up to 14% annual energy savings.

2. Enhanced Safety:

   • Mechanically closes in case of power failure, eliminating the need for additional solenoid valves or super-cap batteries.
   • Reduces the risk of compressor damage and simplifies equipment design.
   • A3 certification qualifies it for use with natural refrigerants, supporting eco-friendly equipment designs.

3. Robust Reliability:

   • Driven by a linear magnetic actuator, which means no friction, mechanical play, or need for lubrication.
   • Maintenance-free design ensures long-lasting performance and reliability even in harsh conditions.

4. Planning and Engineering Efficiency:

   • Designed and tested as a complete system for easy integration into any equipment automation system, lowering development and testing costs.
   • Enhanced serviceability through remote access and diagnostics.
     
     

Case Study: Enhanced Efficiency with Refra Heat Pumps

Refra, a Lithuanian manufacturer of refrigeration equipment, integrated the MVL702 into their reversible propane heat pump design. The results were significant, with up to 8.3% higher COP during heating and a 16.5% increase throughout the entire heating cycle compared to a competitor's stepper valve. This led to a 21% increase in heating capacity and up to 14% reduction in energy consumption, aligning with Refra’s commitment to sustainability and cost savings.
