Butterfly valves for power transformers, with metal-to-metal seals.
According to IEC 60076-22-7, the sealing of the butterfly should not be subject to ageing; therefore, a metal-to-metal design is preferable because the leakage rate does not change over the lifetime of the valve.
Quality standard, durability and performance are featured, which guarantee the safe operation of power transformers.
