Our broad range of products includes valves, actuators and automation technology.

We are able to offer customized solutions for almost every industrial application. Due to our own production line of actuators and automation technology, the valves can always be equipped with the optimal fitting actuator. This is how an excellent matching of both components is guaranteed, which reduces the energy demand.

Series production is our business – the development of customized solutions for special applications is our passion. When a standard valve does not comply with the requirements, we develop a suitable solution in close cooperation with our customer.

Knife Gate Valve with two plates.

Stafsjö’s knife gate valve D2G is a bi-directional tight valve with full bore. The valve is equipped with two hard chromed gates that works towards each other in the bore, which gives an extremely fast operation. This shut-off performance along with its flow characteristics makes it suitable for contaminated media or reject handling. The valve should be mounted only in a vertical pipe line.
