ROYEON ENTERPRISES BUTTERFLY VALVES DESIGN SPECIFICATIONS

Meets the intent and passed AWWA C-504 Section 5* proof of design tests
NSF/ANSI 372 “lead free” in compliance with the U.S. Safe Drinking Water Act effective January 4, 2014.
Extended neck to allow up to 2” of insulation
Dead-End Service: Lug style valves are suitable for end of line service to their rated pressure without the use of a downstream flange (2” - 12” only)
Ideal for ON/OFF and throttling service
Designed for extended service with minimal wear and maintenance. No regular lubrication is necessary
Compatible with ASME Class 125 and Class 150 weld neck or slip-on flanges
Larger wafer body design includes four alignment holes 8” to 12” (DN200 to DN300) WD models
Polyester Body Coating:
• Resistant to ultra-violet radiation
• Resists a broad range of chemicals including dilute acids, alkalis, solvents alcohols, greases, oils
• Resists most impacts without chipping or cracking
Cartridge Style Seat:
• Isolates body and stem from the media
• Provides mating flange seals eliminating the need for separate flange gaskets
• Provides positive shut-off of line media at rated
pressures
EPDM and Buna-N (Nitrile) Seats are Food Grade as standard
Profiled Disc design assures bubble-tight shut-off, minimal torque and longer seal life
Double-D shaft drive 2” to 14” (DN50 - DN350)
Round and keyed shaft drive 16” to 24” (DN400 - DN600)
Blow-out Proof Shaft
Upper and lower shaft bearing ensure longer seat life and lower operating torque
Actuator mounting flange (top plate) conforms to ISO 5211 which allows choice of lever operators, gears and direct mounting of many Apollo pneumatic and electric actuators
