Linak’s electric actuator is a compact maintenance free unit for on/off operations with a speed 7-11 mm/sec. It is available as standard in a 24 V DC version but it can also work on 230 V AC or 120 V AC if it is supplied with a control unit/transformer. 

During first and second quarter 2018 Stafsjö will introduce a new double-acting pneumatic cylinder manufactured by our collegues at Ebro Armaturen. It is a solid construction designed for tough knife gate applications available from 100 mm (4”) up to 320 mm (12.6”) bore diameter. The interface to valve adapter and gate clevis is the same as for the EC cylinder.

Stafsjö’s HG and high pressure version HX features excellent flow characteristics and offers a really safe and reliable bi-directional tight shut-off on highly concentrated media and static media columns. This shut-off performance makes them especially suitable for severe services including pulp stock (pulp concentration <18%), liquor, reject, powder, ash and highly concentrated slurry. Read more and check out the new video on http://www.stafsjo.com/products/knife-gate-valves-hl-and-hg
