KSB BOA-H Metal Bellows Valve PN25 DN65

Full sealing and precise throttling for high-temperature steam and thermal oil systems.

The KSB BOA-H Metal Bellows Valve PN25 DN65 is engineered for complete sealing and precise flow control under high-temperature and high-pressure conditions. Therefore, it suits steam and thermal oil systems that demand leak-free operation. In addition, its GGG40 nodular cast iron body ensures safe service from -10°C to +350°C.

The PN25 pressure class withstands up to 25 bar, moreover the drosselkegel trim allows micrometer-precise flow adjustment. Furthermore, the metal bellows design seals around the stem without environmental contamination, consequently reducing maintenance costs and improving operational continuity. HeizAnlV compliance ensures straightforward integration into heating systems, and the external colour-coded position indicator shows open or closed status instantly.
