AEGIS,

BFV series Butterfly Valves features:Quality AssuranceAEGIS

,BFV series lined butterfly valves are designed, engineered and manufactured under a

company-committed quality assurance process that has been audited and approved by theSQS ISO 9001:2000 for Quality and Management Systems and the PED (PressureEquipment Directive) 97/23/EG for mechanical integrity. All valves are manufactured utilizing modern computer-aided production methods and molding technology, guaranteeingcontrol of the manufacturing process and reduction of rework thus assuring defect free products that are delivered on time. Each valve is individually tested in accordance withAPI 598 specifications and is spark tested with 20,000 volts to assure lining integrity. A PMI process is performed on all critical components allowing material identification. In addition,each valve is subjected to visual and dimensional examinations as well as functional test.Subsequent to successfully completing all testing, each valve is permanently assigned a stainless steel serial numbered identification plate that assures complete traceability. Mill Test Certificates are available upon request.

Design CriteriaAEGIS

,BFV series butterfly valves are designed in accordance with the following specifications:

API 609 ISO 5752/20MSS SP-67 DIN PN 10MSS SP-25 DIN PN 16

Zero Leakage PerformanceAEGIS valves feature an enhanced resilient and non-wetted 360˚ radially loaded, elastomericenergizer. It is isolated and chambered within the valve body to provide uninterrupted uniform sealing pressure to the outer circumference of the liner, resulting in absolute bi-directionalbubble tight shut off. Each valve is tested and certified per the API 598 or the DIN 3230 part 3, leakage rate 1 specifications.

BFV series Butterfly Valves features:

BFV SERIESMaintenance Free, Mechanical Shaft Sealing MechanismAEGIS

,innovative upper and lower dynamically loaded mechanical shaft sealing mechanisms

feature industry proven belleville spring technology that is self-compensating and neverrequires adjustment. The primary seal is the result of a dynamic pre-loaded force being generated at the interface between the PFA encapsulated spherical ball of the disc hub andthe machined concave surface of the PTFE liner. The secondary radial lip seal is created at the interface between the PFA encapsulated stem/extended PTFE collar. The tertiary seal is created by a strategically placed, radially loaded viton o-ring that is positioned around the top of the PTFE extended collar. The unique geometric profiles of the disc and liner eliminate the cold flow and deformation issues typical of conventional lined butterfly valves,resulting in a conditional, environmentally safe, life time shaft seal guarantee.

Disc Swing ClearanceThe disc swing clearance of the AEGIS

,high performance butterfly valve is compatible with

ANSI F423-82 Teflon lined piping systems, as well as fiberglass, carbon steel and exotic piping systems. PTFE lined piping systems with extra thick linings may require the use ofspacers during installation.

Superior Permeation ResistanceDeveloped through years of research AEGIS

,ParaFlon™ lining and proprietary molding

technology utilizes premium grade virgin and unfilled resins to produce superior linings and encapsulations with a minimum thickness of 3mm. Our fully fluorinated polymer molding technology features a substantially greater crystallinity, density, flex life and lowermelt viscosity during the sintering process resulting in long-term resistance to permeation,absorption and swelling. Building a portfolio of documented successful installations, theindustry proven results of our technology is the paragon of performance in some of the most hazardous services such as:

Bromine Chlorinated Organics Nitric Acid Sodium ChlorateCaustic Chlorinated Solvents Oleum Spent AcidChlorine Gas Hydrobromic Acid Phosphoric Acid Sulfuric AcidChlorinated Brine Hydrochloric Acid Phosgene Gas Ultra Pure WaterChlorine Condensate Hydrofluoric Acid Sodium Hypochlorite Vinyl Chloride Monomer Chlorine Dioxide

Size RangeThe standard product is available in ANSI and DIN from sizes 1” – 24” ( DN 25 – DN 600 )wafer and lug style bodies. Valves through size 42” are available upon request and are featured on separate data sheets.

Temperature RatingAEGIS

,valves have a temperature range from – 40˚ F to 450˚ F (depending on liner selection).

Special body materials are available for services below – 40˚ F

BFV SERIESReduced Cold FlowAEGIS

,molecular and mechanically enhanced, ParaFlon™ liner technology is engineered to

reduce the effects of cold flow during the installation of valves between pipe flanges.Featuring spherically molded and machined extra wide liner sealing faces that are securelyanchored within the valve body by a series of machined concentric serrations, our dense innovative technology exhibits superior resistance to the effects cold flow and vacuumplacing the BFV valve in a performance class of its own.

API 609 ConformanceThe API 609 construction of the full body BFV valve is designed to be equally as strong asthe ANSI 150 Lb. counter flanges. Our enhanced certifiable design eliminates the deflectionproblems experienced by conventional double-flanged lined butterfly valves, resulting insuperior flange sealing properties.

ISO 5211 Mounting FlangeThe extra wide integral cast ISO 5211 mounting flange allows the direct mounting ofactuators thus reducing automation cost and eliminating hysteresis.

External Corrosion ProtectionExternal corrosion protection is provided by a two-component, highly corrosion resistant,polyurethane powder coating system.

UPW ServiceValves intended for the meticulous requirements of the semiconductor industry’s UPWservice are assembled and tested in industry-approved clean rooms beneath Class 1000 Hepa Filters, to assure that the environment is grease, dirt, dust, oil and lubricant free. Each valve is thoroughly cleaned via DI water baths and IPA wipe downs. Assembly personnelalso wear semiconductor clean room approved attire during the assembly process.

Chlorine and HCL ValvesAEGIS

,BFV series lined butterfly valves are ideally suited for the stringent performance

requirements demanded with chlorine gas and hydrochloric acid applications. Valves forthese hazardous services are thoroughly cleaned, degreased and packaged per our factoryprocedures and conform to the Chlorine Institute Pamphlet #6 requirements. Our mechanical seal technology and superior ParaFlon™ lining technology offers industriesusing these highly regulated chemicals unparalleled performance and reliability.

SES SystemFugitive emissions are a major concern of operating personnel and surrounding communities within the chemical processing industry. As a result the AEGIS

,BFV valve

has been designed to incorporate an optional Secondary Environmental Sealing System.Featuring dynamically loaded seal packages and monitoring ports that are strategicallyplaced above the primary seal, the SES system safely permits the monitoring of this region.Monitoring systems such as inert gas pads, scrubbers and low-pressure differential switches are easily adapted to the drilled and tapped valve body connection ports.
