Pressure relief valves made of stainless steel, angle-type, with threaded connections

These pressure relief valves for liquids, vapours and gases are extremely versatile and very easy to use. They are suitable both for neutral and non-neutral (inflammable, toxic) media. By means of the stainless steel compression spring either the dealer or the user can set or adjust the required setpressure. This is also ­possible when the valve is installed and under pressure.
Furthermore, the exchangeable cartridge can easily be replaced without having to dismantle the valve from the piping system. In addition, like in all other Goetze valves, this valve has high quality internals, because not only the casing of the valve is made of stainless steel.
