Products


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 Valves

Our sister company in Sweden Stafsj? Valves develop and manufacture high performance shut-off valves for pulp lines in pulp and paper mills, mineral processing and tailing systems in the mining industry, waste/effluent water/sludge handling for utilities and industries, ash handling at power stations and many others.

WB / WB 11

Wafe Type Knife Gate valve for water applications.

These valves are all bi-directional and can therefore be installed into pipe systems independent of pressure direction. Full bore and excellent flow characteristics makes them suitable for fluids, sludge and liquids with solids in suspensions such as water, sewage and bio mass.

WB 12

Knife Gate Valve

These valves are all bi-directional and can therefore be installed into pipe systems independent of pressure direction. Full bore and excellent flow characteristics makes them suitable for fluids, sludge and liquids with solids in suspensions such as water, sewage and bio mass.

WB 14

Lug Type Knife Gate Valve for water applications.

These valves are all bi-directional and can therefore be installed into pipe systems independent of pressure direction. Full bore and excellent flow characteristics makes them suitable for fluids, sludge and liquids with solids in suspensions such as water, sewage and bio mass.

WB 14E

Stainless Steel Lug Type Knife Gate Valve.

Stafsj?’s WB14E knife gate valve is a high performance shut-off valve with superior flow characteristics, offering bi-directional zero leakage shut-off up to 150 psi/10 bar. It is suitable for media such as pulp stock, chemicals, sludge, bio mass, slurry and water. The fully lugged body design is suitable for dead-end services.

MV

Universally applicable Knife Gate Valve.

Stafsj?’s knife gate valve MV is used within many different fields of applications. The valve has a gate with a bevel edge that effectively cuts through different media. In closed position the gate is pushed onto the seat which gives a tight and reliable sealing. This special shut-off technique makes the MV valve suitable for both fluids and dry media such as pulp, sludge, biomass, powder and different kinds of waste.

XV

Knife Gate Valve

Stafsj?’s knife gate valve XV gives a secure and tight shut-off, independent of pressure direction. The valve has good flow characteristics and can be used in applications with pulp, biomass and sludge, and the Polyurethane seated version further extend its field of applications to abrasive media.

HG

A bi-directional tight Knife Gate Valve with a through-going plate.

Stafsj?’s knife gate valves?HG have excellent flow characteristics and gives a bi-directional tight sealing.?

HP

Knife Gate Valve for high pressure applications.

Stafsj?’s high pressure knife gate valves HP, HPT and HX are all strenthened to withstand high bi-directional pressures. They are equipped with through-going "O" port gates and this secure a really safe and reliable shut-off of static and highly concentrated media. This shut-off performance, along with its excellent flow characteristics, makes them suitable for really demanding operating conditions with media as pulp (pulp concentration < 18%), liqour and highly concentrated slurry.

HPT

Knife Gate Valves for high pressure applications.

Stafsj?’s high pressure knife gate valves HP, HPT and HX are all strenthened to withstand high bi-directional pressures. They are equipped with through-going "O" port gates and this secure a really safe and reliable shut-off of static and highly concentrated media. This shut-off performance, along with its excellent flow characteristics, makes them suitable for really demanding operating conditions with media as pulp (pulp concentration < 18%), liqour and highly concentrated slurry.

RKO

Knife Gate Valve for abrasive media.

Stafsj?’s knife gate valve RKO is reliable and particularly well suited for demanding reject and other abrasive media. The valve’s circular inlet and square outlet together with the gate, that has a rectangular shape and a bevel edge, counteracts clogging and blockages, which often is a problem in combination with junk traps, coarse reject and cleaners.

JT

Knife Gate Valve

This complete Junk Trap is designed for really tough process conditions handling difficult and abrasive media. The JT is specially designed to minimize turbulence, erosive wear, and build-up of solids and reject material.

D2G

Knife Gate Valve with two plates.

Stafsj?’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.

SLV

Knife Gate Valve for abrasive slurry.

Stafsj?’s knife gate valves SLV and SLF are particularly suitable for abrasive and demanding slurry 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.

SLF

Knife Gate Valve

Stafsj?’s knife gate valves SLV and SLF are particularly suitable for abrasive and demanding slurry 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.

SLX

High pressure knife gate valve

Stafsj?’s knife gate valves SLH and SLX are designed for the most demanding high pressure applications with slurry and other abrasive media where operation reliability and low life cycle cost are emphasized. The SLH is designed for pressure up 20 bar/290 psi while the SLX is designed for 50 bar/720 psi.

TV

Knife Gate Valve

Stafsj?’s knife gate valve TV is used as an isolation valve for a transmitter or sensor on a tank for which a short face-to-face length is required.
