Stafsjo Series - HL & HG Series Full bore Knife Gate Valves
Stafsjö’s knife gate valve HL
has a full bore with excellent flow characteristics. The valve is equipped with
a through-going gate for secure bi-directional shut-off of concentrated and
static media. This shut-off performance, along with its flow characteristics,
makes it suitable for severe operating conditions with media such as pulp (pulp
concentration > 5%), liquor, reject, powder and ash. HL is supplied as
standard with a valve body in stainless steel, which has integrated purge ports
and guiding strips.
To be able to cope with bi-directional pressures, the HL
has the retainer ring system on both body halves. The valve is equipped with a
gate in stainless steel, but duplex material and hard chromed surface are
options to increase the wear resistance. The gland boxes are equipped with
Stafsjö’s box packing TwinPack™, to secure that no media reaches surrounding
environment. The top work consists of aluminium beams and stainless steel tie
rods, which gives good corrosion resistance and a stable operation.
The valve
is modular designed and can easily be customized to specific processes
requirements. There are several actuator types and accessories to choose from
in our standard collection.
The HL valve is designed, manufactured, inspected
and tested according to the European Pressure Equipment Directive (PED 97/
23/EC) category I and II module A1. The valve is CE marked when it is
applicable. The HL valve is one out of five valves in Stafsjö’s procuct range
with through-going gates.
The HG represent the standard. HP is a high pressure
version of HG and the HPT is a high pressure version entirely made in Titanium.
Finally the HX is an extreme high pressure version.
