1 A heavy duty double flanged concentric design resilient seated butterfly valve FEATURES GENERAL APPLICATION These valves are for water or air service where a drop-tight shut-off and double flanged body are required. TECHNICAL DATA Pressure (psi): 150 psi NPS End of line (psi): 90 psi NPS Vacuum service (psia): 5.8 psia Temperature ( F): -40 to +320 Sizes (NPS): Flange accommodation: PN 10 ASME 125/150 AWWA C207 Table B/D/E JIS 10K AS4087 PN 16 AS2129 Table D/E Flange facing: Flat face (standard) Raised face (option) 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 Pentair plc. All rights reserved. VCTDS US 14/11

6 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.
