German standard Y-type straight through bellows globe valve
The German Standard Y-Type Straight Through Bellows Globe Valve combines a streamlined Y-pattern body with a welded bellows sealing system. This design minimizes pressure loss while eliminating stem leakage. Ideal for steam, thermal oil, gas, and chemical media, it delivers reliable shut-off, environmental safety, and long service life.
German standard Y-type straight through bellows globe valve
The German Standard Y-Type Straight Through Bellows Globe Valve is designed according to DIN standards and features a Y-pattern flow path that significantly reduces flow resistance compared to conventional globe valves. The stainless steel bellows assembly provides hermetic stem sealing, preventing external leakage and ensuring safe operation.
Its straight-through design enhances flow efficiency, reduces turbulence, and lowers energy consumption. The valve is widely used in power plants, petrochemical facilities, thermal oil systems, pharmaceutical plants, and industrial gas pipelines where leak-free operation is essential.
German Standard Y-Type Straight Through Bellows Globe Valves are manufactured and tested according to international standards:
