Pipeline blinding equipment

Version for printing

Spectacle blind (obturator) is traditional, but not so comfortable in operation solution: it requires to drain pipeline and disassemble flanges coupling every time

Turning or shifting line  blinds enable to reduce operation time dramati­cally: its require just to loosen and tighten several fixative nuts. Nevertheless, draining of the pipeline is also required

Blind flange valve enables avoid draining – the hole-less body keeps media inside. The operation is very simple: just to remove the cover and put in/pull out the shut-off insert with the tightening cheeks

Fitting-in blind makes to block pipeline possible without depressurization. The shut-off insert maybe fit in and extracted with a special tool

At least, dual expanding plug valve, equipped with gearbox or electric actuator, enables to avoid manual works completely. Special design of the shut-off piece (90° turning wedge with lateral  tightening cheeks) grants 100% bi-directional tightness
