• 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.
• 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.

Keystone Series GR Resilient Seated Butterfly Valves
GRF
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 32°F 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 32°F 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 32°F 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 -14°F 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 50 psi.
