• Double flanged body design with face-to-face
dimensions, according to EN 558 Series 20,
API 609 and AWWA C504 short.
• 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.
• Rounded polished disc edge gives full
concentric sealing, lower torques, longer seat
life and drop-tight shut-off.
• 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 (97/23/EU) Module B1 + D,
CE Marking.
• Available approvals: ABS, NSF/ANSI STD 61.

NOTES
1. ‘Q’ dimension is the minimum allowable pipe or flange inside diameter at the centered body face to protect
the disc sealing edge against damage when opening the valve.
2. Weight may vary depending on trim materials used.
3. EN 558 standard allows for both 165 & 190 mm face to face on DN 750. FTF of 190 mm is standard with
165 mm FTF as an option. Consult factory for availability.
4. Tap depth.
5. See installation, operation and maintenance manual (IOM) for detailed bolting information.

NOTES
1. ‘Q’ dimension is the minimum allowable pipe or flange inside diameter at the centered body face to protect
the disc sealing edge against damage when opening the valve.
2. Weight may vary depending on trim materials used.
3. Tap depth.

KEYSTONE SERIES GRF RESILIENT SEATED BUTTERFLY VALVES
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 & 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.
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.
Application IV
a. Dry abrasive media and degreasing applications (sand, cement, silicone free, oxygen cleaned); or
b. Liquids with severe deposit; or
c. Valves not frequently operated (once a year).
All above with temperature range from -10°C to maximum temperature rating of the elastomer seat.
NOTES
1. For applications with temperatures above or below the guidelines above, please consult factory.
2. For dry service valves it is suggested to use U/C discs (reduced diameter) when service conditions are less than 3.5 bar.
