Pressure safety valves (PSV)

Functional area

Pressure safety valve (PSV) DN 40000/60000 mm of series 788, manufactured with three different modifications is a direct acting safety device designed for installation in the reduced and desuperheated steam after pressure-reducing and desuperheating stations.

Setting up

The valve is installed on the horizontal parts of the pipelines with stem upwards; in areas where maintenance is easy. The valve body is equipped with mounting legs for easy installation during construction.


Pressure safety valve operates in auto mode – the valve closes at nominal pipeline pressure. Gate actuates when the pressure in a package boiler increases above mount pressure and steam releases into atmosphere. With decreasing pressure in a pipeline, the force created by the load lever exceeds the force created by the pressure of the gate, the gate drops down, and the valve closes.

Valve body material – carbon steel.
Connection to the pipeline – flanged connection.
Manufacturing and shipping according to TS 3742-006-71228244-2008 standard.
