Electronic Expansion Valves

Siemens AG is a global technology powerhouse that brings together the digital and physical worlds to benefit customers and society.

The company focuses on intelligent infrastructure for buildings and decentralized energy systems, on automation and digitalization in the process and manufacturing industries, and on smart mobility solutions for rail and road transport.

Within Building Technologies, Siemens offers a comprehensive range of valves for various applications in refrigeration and industrial cooling:

  • Heat recovery
  • Expansion
  • Hot-gas
  • Suction throttle

Specifically, the new generation MVL661.. and MVS661..N valves are a fine-tuned valve series which cover a wide range of application areas. Specifically, these valves cover the three application areas of expansion, hot gas and suction throttle. As such, just one valve series covers all common safety refrigerants.

The MVS661..N refrigeration valve was developed for ammonia refrigeration applications offering a new dimension in the control of ammonia refrigeration plants.

Moreover, Siemens offers a PolyCool™ Superheat control system, which, together with its associated components ensures optimum operation of the refrigeration unit.

In addition, Siemens offers a full line of valves and actuators designed for precise regulation and control of water, steam and other media.

Dicostock S.L. distributes the following components from Siemens:

  • MVL661 and MVS661..N magnetic refrigeration valves
  • PolyCool™ Superheat Control (PolyCool™ CPS40)
  • Valves for secondary circuits
