Insulation gate valve
Insulation gate valve
Nominal pressure: 1.6Mpa ~ 2.5Mpa
Nominal diameter: DN15 ~ 300mm
Material: LCB, LF1, LF3, LC3 , CF8, F304 , etc.
Temperature: ≤350 ℃
Suitable medium: ethylene, propylene, liquid nitrogen, Liquid hydrogen
Insulation gate valve features
1, the fluid resistance is small, the sealing surface by the media brush and erosion of small.
2, opening and closing more effort.
3, the media flow is not restricted, no spoiler, do not reduce the pressure.
4, simple shape, short structure length, manufacturing process is good, for a wide range.
