FEATURES
• Wafer and lugged body design with
face-to-face dimension, according to
EN 558 Series 20 and API 609.
• Designed according to EN 593 and API 609.
• The seat is field replaceable and fully isolates
the body and shaft from the flow.
• Primary shaft sealing exceeds the pressure
rating of the valve and prevents leakage
through shaft area to atmosphere.
• A secondary shaft sealing provides back-up
safety.
• A molded-in O-ring in the seat for flange
sealing eliminates the need for gaskets.
• Shaft seals prevent moisture penetrating into
the shaft area.
• The two piece shaft allows for a thin disc
and provides minimal obstruction to flow
(up to DN 300).
• Rounded polished disc edge gives full
concentric sealing, lower torques, longer seat
life and drop-tight shut-off.
• Body locating holes allow ease of installation
and centering between the flanges.
• Extended body neck allows for pipe insulation.
• Actuator flange according to ISO 5211.
• Top and bottom shaft bearings for optimized
support and minimum friction and decreased
torque.
• Top bushing absorbs actuator side thrust
loads.
• All valves comply to Pressure Equipment
Directive (2014/68/EU) Module B + D,
CE Marking.
• Available approvals: NSF/ANSI 61, ACS,
KIWA, WRAS, DVGW-G, ABS, CU-TR.
• Sizes DN 20 up to DN 40 might deviate from
the above mentioned features. Please contact
factory.

TORQUE APPLICATION FACTOR CATEGORIES
Application I
Clean liquid lubricating media (water, clean oils, lube oil, mineral oil, etc.); and with no deposit or
chemical attack, valve operated at least once a week.
Temperature range from 0°C to maximum temperature rating of the elastomer seat.
Application II
Other liquid media and lubricating gases (aqueous liquids, such as food and beverage, water, etc.);
and with minor deposit or chemical attack, valve operated at least once a month.
Temperature range from 0°C to maximum temperature rating of the elastomer seat.
NOTES
As the reinforced seat is intended for high pressure
applications the base torque commences at
1000kPa/10 bar.
Reinforced seat are suitable for:
Severe vacuum application (use 10 bar torque values).
•
• High line velocities up to 12 m/s for liquids.
• Pressure testing during erection and
commissioning.
Application III
a. Dry non-abrasive media or gases (non-abrasive powders and dry gas); or
b. Fluids with moderate deposit or chemical attack; or
c. Valves operated less than once a month.
Temperature range from 0°C to maximum temperature rating of the elastomer seat.
NOTE
1. For applications with temperatures above or below the guidelines above, please consult factory.
