The pressure reduction occurs by throttling the free cross section between the seat and the cone. Any change in pressure on the downstream pressure side is immediately converted into a lifting movement of the valve cone.

There is no need for additional accessories such as a water seal pot. It is possible to install the valve quick and easy.
They are mainly used in industrial plants, plant engineering and process engineering.
Pressure reducing valves can be supplied with flanges, weld ends or threaded connections.

Description
Low-pressure reducing and relief valves regulate pressures in mbar range and serve the inertisation and blanketing of containers, reactors, stirrer vessels, centrifuges, etc. with inert gas such as nitrogen.
Inertisation For discontinuous batch processes before process start, the reactor chamber is rendered inert. The inertisation of spaces describes the process to displace the oxygen in the air or other reactive or explosive gases or gas compounds by adding of inert gas

DESCRIPTION Tank blanketing valves are commonly used in tank storage systems to prevent and protect against explosions (avoiding flammable liquids being vented from vessel), to control product contamination against external air that may fill the vapour space, to reduce evaporation losses (consequently product losses), to reduce internal corrosion (caused by air and moisture) and to prevent vacuum condition. The blanketing process consists in covering the stored medium, usually a liquid, with a gas (normally N2). MAIN FEATURES Compact design. No rising stem, except when supplied with top cap.
