Description
The valve respiratory KDM - 50 mechanical - with the built - in fire prevention device is intended for sealing of gas space of tanks with light oil products and regulations of pressure in this space in the set limits for the purpose of reduction of losses from evaporation of oil products and reduction of environmental pollution.
The KDM - 50 valve are established on an assembly branch pipe on a tank roof through a connecting flange of an adapter. For protection against direct impact of an atmospheric precipitation and wind the valve has a cover.
On resistance to influence of climatic factors of the external environment valves are manufactured performed by U, UHL of category of placement 1 in accordance with GOST 15150 - 69.
