2 Intended Use
WARNING
Control valves are pressure ves-
sels designed and rated for spe-
cific application conditions. Before installation, check the
serial number and / or the tag number to ensure that the
valve and actuator being installed are correct for the in-
tended application. Do not use the valve outside of its rated
design limits. Exceeding the design limits may cause haz-
ardous conditions including leakage of the process media
or rupture of the pressure boundary resulting in possible
process loss, equipment or environmental damage, or seri-
ous personal injury or death.
The specific product design data can be found on the valve’s
serial plate, data sheet and the calculation sheet (in acc. to the
IEC 60534-7:2010).
The Valtek GS handles a wide variety of general service ap-
plications, while offering high flow capacity. All sizes come
standard with unbalanced trim; for high pressure drop appli-
cations optional pressure balanced trim is available for NPS
sizes 3 to 6 (DIN size 80 to 150).
The Valtek GS consists of the body, bonnet, trim, and actuator.
The valve is designed with a high level of interchangeability al-
lowing the user to assemble the greatest possible number of
variations from a minimum number of components to match
each application. There are two bonnet designs, standard /
extended bonnets and bellows seal bonnets. See Figure 1 and
Figure 2.
The Valtek GS is designed in compliance with EN 1349:2009
- Industrial Process Control Valves (DIN EN 1349 and VDE
0409-1349).
The Valtek GS is designed for use in MODERATE and WORLD-
WIDE environmental conditions, ambient temperature range
-40°F to 158°F (-40°C to +70°C), air humidity up to 93% non-
condensing, air pollution up to 300 µg/m

, unless restricted
by the accessories.
The product offering may include optional ancillary equip-
ment, such as positioners, air-filter regulators, solenoid
valves, limit switches or boosters. Digital, I/P, or pneumatic

or according to NAMUR standards. Refer to the relevant man-
ufacturer‘s user instructions for information regarding other
ancillary equipment.
