The goggle damper consists of a specially designed valve which is used when there is a need to isolate an area of piping to allow people to gain access, without air sealing and in environments with high concentrations of dust. Once the gate is closed, it is then pushed by hydraulic jacks to press it against the closure, thus ensuring air tightness.
