Extreme cold and heat: when expansion valves reach their limits.
Expansion valves are the heart of modern refrigeration systems and heat pumps.

They control the refrigerant flow to the evaporator, directly shaping the efficiency and operational reliability of the entire system.

Internal leaks, fluctuating temperatures, high pressure differences, and aggressive media place significant demands on the components involved – often exactly where standard solutions reach their limits.

Our ceramic control discs are designed for this: they minimize internal leaks,offer excellent sliding properties, and enable precise control – even under high pressures and changing temperatures.

The result: stable processes, reduced energy loss, and a significantly longer service life for the system.

Typical application areas:

• Expansion valves in refrigeration systems – precise control of the refrigerant flow
• Heat pumps – reliable sealing at high pressure differences
• Industrial refrigeration and air conditioning systems – durable components for continuous operation

Where does wear on control components currently limit the efficiency of your refrigeration or heat pump application?
