Applicat ions -Designed for cylinder regulator applications. - Ideally suited to put vessels under pressure, leak detection and purge of pipe work. Key features -Similar to the series S250 but with a higher possible outlet pressure (200 bar) - Decompression of the downstream regulation system possible by turning the hand wheel counter -clockwise (SL 400). - Accurate pressure control for reliable service. - The SLS 400 version has a connection available so that a relief valve can be installed. - Panel mounting possible due the rear threads. - Can also be equipped with a shut off valve at the outlet.
