HRS和HRSB型检修阀
维修阀
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.

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.
