Siemens Building Technology MVL661.20-2.5 7/8" Refrigerant Valve

Siemens Building Technology MVL661.20-2.5 7/8" Refrigerant Valve is a modulating control component used to regulate flow in cooling and heat pump circuits. It operates with an integrated magnetic actuator that adjusts valve position based on a control signal allowing precise modulation of flow through the loop. In HVAC systems, it is installed in chillers and air conditioning circuits where accurate control is required for stable cooling performance. It manages expansion, throttling and pressure conditions between components such as the compressor and evaporator ensuring controlled heat exchange and efficient system operation under conditions.
