STOP GLOBE VALVES FORGED CONSTRUCTION (ROV)
Globe valves, forged construction operate in thermal stations, in chemical and petrochemical industry as well as in other sectors that use fluids with the working temperature up to 570°C (fluids like water, steam, gases and petroleum products).
The products are designed and manufactured according to the Law 608/2001 and HG 584/2004.
