DIN Bellows globe valves are often used to cut off, distribute and change the flow direction of the medium control components.

The seat surfacing nickel alloy,has good wear resistance, corrosion resistance, friction resistance and long service life.

Depending on the stem pressure, the disc sealing surface is closely fitted with the seat sealing surface to prevent the flow of media.

Medium:Steam, gases, hot water, thermal fluids, hot oil, process water, vacuum facilities, ammonia etc.

Face to face dimensions according to EN558-1 (DIN3202 F1 Series)
