The inline shut-off valve with BSP external thread is used to stop the flow of the medium in the installation. It is intended for air installations, and it can also be used with non-flammable and non-toxic gases (nitrogen, carbon dioxide, helium, argon, etc.). The closure of the shut-off valve is achieved by manually turning the knob, which moves the ball until it is completely sealed. The direction of flow is indicated by an arrow on the valve body. Maximum constant working pressure across the full temperature range. Body material: brass. Ball material: stainless steel AISI 304. Stem sealing: NBR. Working pressure: from 25 bar to 40 bar, depending on the internal diameter DN. Operating temperature: from -10°C to +90°C.
