Globe valve made of steel, with flanges, PN 40. With a rising, externally threaded spindle and flat sealing surfaces. Valves, from DN 125 has a pressure-relieved globe/cone as a standard, which means that the direction of the flow is from the opposte side, i.g top and botom. A shut-off valve for steam, condensate and hot water.

- Can be mounted in any position except with handwheel pointing downwards.
- The system has to be flushed clean before startup.
- Valves DN15-100 have a flow direction from bottom to top.
- Valves DN125-150 have a reversed flow direction (eg from top to bottom).
However the flow direction is always marked by an arrow on the body.
