Valves the respiratory combined KDSA 3000 are intended for maintenance of pressure in gas space of tanks in the set limits and sealing of gas space of tanks for the purpose of reduction of losses of a neta and oil products from evaporation and decrease in pollution of the atmosphere by their couples.
KDSA can be used both as respiratory, and as safety valves. On tanks they have to be established completely - one as the respiratory valve, another as safety.
Valves are designed and are manufactured performed by UHL. The KDSA valve has such advantages before analogs as simplicity of service at surveys without use of the special tool, a possibility of change of pressure of operation, a possibility of replacement of fire prevention devices without dismantle of the valve.
