Valve block units in angle version can be used at facilities where the circumstances are such that it would be difficult to assemble a linear block unit due to the face-to-face length. Furthermore, such units can be used in the process of design and development of measures aimed at restructuring of heat and power facilities, where the replacement of outdated gas train is required and the space is limited due to the existing gas pipeline supply, location of the boiler units and gas igniters.
