Stafsjö’s knife gate valve HG is a bi-directional valve, particularly
well suited for severe operating conditions where there is a risk
for clogging. A throughgoing gate assures closing of the valve
through static media. Common media are pulp (concentration
> 5%), caustic liquor, reject and waste.
The HG-valve is designed of a two piece valve body in stainless steel or cast iron. Purge ports are standard on the valve on
sizes DN 100 - DN 800. HG is equipped with a gate in stainless steel, built-in guiding pads on larger sizes and removable
retainer rings, which simplifies changing of the seats. Stafsjö’s
unique box packing, TwinPack™, gives a tight sealing and assures high operation reliability.
The valve is modular designed and it can easily be provided
with different actuators and accessories.
Stafsjö’s knife gate valve HG is designed, manufactured,
inspected and tested according to the European Pressure
Equipment Directive (PED 97/23/EC) category II module A1.
The valve is therefore CE-marked.
The HG-valve is also available in an ATEX design (ATEX 94/
9/EC II cat 3 G/D for zone 2 and 22). Please contact Stafsjö or
your local representative for more information and advice.

Pressure tests
Pressure tests are performed with water at 20º C according to EN 12266-1:2003.
Pressure for shell test: 1,5 times maximum allowable working pressure for open valve.
Pressure for seat tightness test: 1,1 times maximum allowable differential pressure for closed valve.
