The GID electric high vacuum butterfly valve is designed for use in non-corrosive, saturated steam and low-vacuum pipelines. It functions as a closed-circuit control device. The valve features a sealed butterfly design with dual shaft seals that ensure no leakage under 0.25MPa pressure. The structure of the NKD941X-25C model includes two seats and a narrowed shaft, combined with rubber sealing at 0.25MPa to enhance performance. An electric heating assembly can be optionally installed on the valve body if required.
