Service Valves, type HRS, HRSB und HRSN
Service Valves
GEA service valves and GEA Needle Valves are designed to attach additional devices such as manometers to heating and refrigeration systems. Therefore they are available with various types of connections. They have a locking function that can be operated with a handwheel or a ratchet. With valve types HRS and HRSN, the stem is sealed by means of a screw bush. With valve type HRSB, the stem sealing is provided by a threaded bush and a metal bellows for completely hermetic sealing. The valves are also equipped with a back seal. When the valve is fully open, it is possible to replace the threaded bush and the seal without interrupting operation.

GEA Insights
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.
Fueling the circular economy in shipping
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
Closing the loop: key lessons for breweries from OeTTINGER
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
