KV Ball Valve
KV Ball Valves
GEA ball valves (KV) are designed for installation in industrial heating and refrigeration systems. The closing device is a bored through ball that opens and closes the pipe by horizontal rotation in relation to the flow direction. The 90° rotation is exerted via the shaft and is either by a hand-operated lever or by electric or pneumatic actuators. By default the bore size in the ball is smaller than the inside diameter of the pipe, versions with full clearance are also available upon request.
Ball Valve type KV
Technical Features
- Available in steel or stainless steel
- Selection of body material as per German DIN EN12284, AD2000 Series W
- Working mediums: refrigerants as per EN 378 p. 1, e.g. NH3, R22, R134a and blends with refrigerator oil; neutral, gaseous and liquid media; glycol-based cold brine
- The bored through ball is provided with a vent to the supply line to equalize pressure when closed
- Closes tight only in the flow direction
- Actuation either by hand-operated lever or by electrically or pneumatically powered actuators

A new recipe for indulgence
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
