The direct-acting pressure safety valves are intended for the equipment protection against overpressure of the working medium higher than the allowed value.
The valve is closed in case of steam pressure reduction in the site protected up to a definite value of the working pressure.
The choice of the pressure safety valve from the product line, represented in the catalogue, is carried out depending
on the working medium parameters in the site protected
and the required throughput capability.
The quantity of the pressure safety valves and their throughput capability for general-purpose power supply plants shall be chosen as per calculation according to the Regulatory Technical Documentation agreed with the Federal Service for Environmental, Technological and Nuclear Supervision of the Russian Federation.
