Sempell Model 155 high pressure reducing valves

Sempell Model 155 high pressure reducing valves

Sempell™ model 155, angular steam reducing valve, is designed for start-up control and process steam control. An optimum-staged CV-value-series and a large turn-down ratio allow an exact adjustment to the pertaining task. The trim can be easily changed, thus an adjustment to subsequently changed operational conditions is possible. A combination of material choice and multi-stage pressure reduction by a radial cage system ensures high wear resistant in spite of extreme working conditions.
