H247H Pneumatic High Temperature Multilayer Metal Seal Butterfly Check Valve
Description
Brief Introduction
H247H Pneumatic High Temperature Multilayer Metal Seal Butterfly Check Valve is suitable for pipeline with temperature less than 425℃ and steam or micro dust media, to avoid media flow back, to protect fan, pipeline and so on
Features
1 Disc automatically close or open under the pressure of media, with the function of power-assist buffering and disc force closing
2 Working with cylinder, to ensure valve quick force closing.
3 Valve is assembled with disc open/close signal device.
4 Valve is assembled with device to precisely control disc open degree.
5 Triple offset, low sealing surface abrasion, long service life and O leakage.
6 Reasonable structure, working performance is reliable.
