Product information

About XV

Stafsjö’s knife gate valve XV offers excellent flow characteristics and bi-directional zero leakage shut-off. It is a compact chemical resistant valve suitable for media such as pulp stock, biomass and sludge. ​

The XV valve is as standard supplied with PTFE seats and stainless steel wetted parts. The valve body is available in a fully lugged version up to DN 600/24″ and a semi lugged version all the way up to up to DN 1000/40″. There is also a dead end service version available in DN 80/3″ – DN 200/8″. The high strength top works consist of stainless steel tie rods encapsulated inside structural beams. Stafsjö’s gland box system with TwinPack braids and a extra scraper ensures that no media reaches the surrounding environment. 

The XV valve is modular designed and can easily be equipped with manual as well as automatic actuators and related automation accessories.
