This 8011 GSI pressure regulator has a compact body and closed spring hood. This is useful for many forms of engineering items and can work in many chemical and plant construction situations as well since it is compatible with a range of media, from neutral to highly aggressive. This can also be configured as either a pressure reducer or downstream pressure regulator, or as an overflow valve (upstream regulator). The regulator ranges from DN 15-125, with a PN of 16-40.
