Blocks of shut-off (disconnecting), switching valves (BZA, BPA, BOA)

Purpose of block valves: Blocks of shut-off (BZA), switching (BPA) and shut-off (BOA) valves are intended for distribution, cleaning and measurement of the flow rate of natural gas, liquid hydrocarbons, chemical liquids and process water (hereinafter referred to as the pumped medium), distributed separately – new technological facilities with a working pressure of up to 16 MPa, as well as to protect collectors and loops from overpressure, to cut off flows in the event of a rupture of loops. Operating conditions of blocks of shut-off valves: Blocks of shut-off valves (BZA, BPA, BOA) are intended for operation in macroclimatic regions with a moderate (U) and moderately cold climate (UHL), as well as in areas with a cold climate (CL). The climatic version of the blocks is chosen depending on the construction area, in accordance with the requirements of GOST 15150-69. Composition of valves: The equipment of the blocks of valves is mounted on a welded frame and is located in a heat-insulated room. The class of the explosive zone of the technological unit is B1a. Technological compartment. includes: pipeline lines; drainage system with a drainage manifold; shut-off and control valves for pipelines and drainage; filters; automatic sensors and signaling devices; ventilation, heating and lighting system; control of electrical equipment installed in the technological room of the unit (room heaters, lighting, fan, sensors ) is produced from the control cabinet. brand of flow meter, meter; presence of filters; quantity and composition of instrumentation; ventilation systems; type of room shelter; presence of room heating.
