The EV METAL.DK program of Slimline Block and Bleed Valves - in the following referred to as SDBB valves - offers a compact lightweight instrument double block and bleed function. These compact models have the lowest possible number of leak potentials from a process connection as it involves one joint only – the pipeline flange to the valve body. The SDBB valves can be mounted directly onto vertical or horizontal flanged connections, allowing a gauge to be kept in an upright position. Suitable for both primary isolation (double block and bleed) and instrument (block and bleed) duties, Mono block provides isolation, venting and instrument mounting in a single compact unit.
