Valtek GS

1 Scope of Manual

The following user information covers the Valtek GS general
service control valve:
• Metric DIN Units - PN 16 / 40, DN 15 - 150
• English ASME Units - Class 150 / 300, NPS ½ - 6
• Assembled with a pneumatic or electric linear actuator
• Comes with or without ancillary equipment

2 Intended Use

Control valves are pressure ves-
WARNING
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 noise level emitted by control valves is always determined
by the operating data and the installation situation and is dif-
ferent for each application. There is no general typical value for
this. In any case, technical measures are used to try to keep
this below 80 dB(A). The individually expected pre-calculation
noise level can be found in the calculation data sheets.
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 FlowTop is designed for use in MODERATE and
WORLDWIDE environmental conditions. However, the inten-
ded use of the pneumatic actuators and the accessories is
limited by their permissible ambient temperature application
FCD VLEEIM0300-05 (EN/A4) November 2022
limits. When operated in the moderate range, a service life
of 7 to 10 years can be expected before servicing. Leaks can
occur at low temperatures (-60°C to -25°C), at high tempera-
tures permanent damage to the elastomers (+60°C to +80°C,
expected service life then < 1 year). Humidity up to 93% non-
condensing, air pollution up to 300 µg/m
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
positioners can be mounted directly, with a mounting bracket
or according to NAMUR standards. Refer to the relevant man-
ufacturer's user instructions for information regarding other
ancillary equipment.

3 Product Identification

Each Valtek GS control valve comes with an attached serial
plate which includes key information specifically for each con-
trol valve:

and spare parts lists. Other information located on the serial
plate is self-explanatory for the Valtek GS control valve.
You can download .pdf versions of the Valtek GS documenta-
tion including a sales brochure, technical bulletin and user
