Welding vacuum globe valve

The welding vacuum globe valve NKJ61 produced by Shanghai Guanhuan Valve Manufacturing Co., Ltd. adopts a cast and forged structure for the main body of the welding vacuum globe valve, with parallel double sealing pairs and semi forced bidirectional sealing. The sealing surface moves in place and the wedge-shaped block moves step by step to achieve zero leakage. It is suitable for pipelines with working temperatures ≤ 425 ℃ and ≤ 550 ℃ and working media of water, air, and steam, as a starting and closing device

Produced by Shanghai Guanhuan Valve Manufacturing Co., LtdWelding vacuum globe valve, NKJ61 welding vacuum globe valveThe main body adopts a cast and forged structure, with parallel double sealing pairs and semi forced bidirectional sealing. The sealing surface moves in place and the wedge-shaped block moves step by step to achieve zero leakage. It is suitable for pipelines with working temperatures ≤ 425 ℃ and ≤ 550 ℃ and working media of water, air, and steam, as a starting and closing device. Especially suitable for steam turbine condensation and vacuum negative pressure systems in thermal power plants, it plays a role in vacuum sealing and isolation.
