The HX valve is an extreme high pressure valve for severe operating conditions, high pressures and concentrated media within several field of applications. It is also a complement to the existing range of through-going "O" port gates, the HL, HG, HP and HPT, that have been proving for decades a really safe and reliable shut-off of static media columns, such as pulp up to 18%. 

In 1928 our knife gate valve manufacturing started in close co-operation with nearby pulp and paper mills. Now it is time for the eighth knife gate valve generation, the MP, which is a result of market driven requirements and experienced engineering throughout the years. 

The HL knife gate valve is developed to complement our existing product range with bi-directional knife gate valves with through-going gates. The HL is designed to work under similar process conditions as the well known HG and the high pressure valve HP, but in lower pressure classes. 

Stafsjö’s knife gate valves SLV and SLF are developed for slurry and abrasive applications where operation reliability and low life cycle cost are emphasized. The SLV is a lugged version while the SLF is fully flanged and especially suitable on old non-centred pipes or low pressure applications.
