XOMOX® Series 9000 Triple Offset Butterfly Valves (TOV)
For harsh conditions requiring metal seats with zero leakage in critical process applications, steam isolation, high cycle frequency and high temperatures, the Xomox triple-offset valve provides unmatched performance, reliability, and quality. The superior design of the disc / shaft engagement and the precision machined sealing components combine with innovative design geometry to provide improved cycle life, lower operating torque, and reliable performance in extreme temperatures.
Triple-offset design elimates wear associated with sealing surface contact and maintains sealing integrity and high cycle life
Wide angle seat design eliminates wedging and binding of the disc seal in the body seat
Torque seated resilient metal seal ring provides reliable zero leakage, bi-directional closure from -320°F to +1,000°F
Bubble-tight closure provides process efficiency with reduced cost of maintenance
Self-centering disc design accomodates thermal extremes without binding
Robust single-piece shaft minimizes shaft deflection and permits bi-directional sealing
Optional stellite body seat offers optimum resistance to erosion in abrasive and high velocity applications
No Plastics or elastomers provides fire-safe system security at extreme temperatures
Bearing protector rings prevent solid particles from coming in contact with bearing surfaces
Blowout-proof shaft complies with API 609 to improve safety for operating personnel
API 609 lug body design means XOMOX series 9000 Severe Service Butterfly Valves are interchangeable with most double-offset high performance butterfly valves
Optional ASME B16.10 flanged design means XOMOX Series 9000 Severe Service Butterfly Valves are interchangeable with gate and ball valve lay lengths
Quarter-turn design reduces emissions and improves containment integrity
Xomox offers a broad range of high performance butterfly valves to handle virtually any process application. Available to fit ASME (ANSI) or DIN piping systems in pressure classes 150, 300 and 600 (PN 10/16, PN 25/40, and PN63/100). Standard valves are offered with soft (PTFE) seats, Fire-tested, or high temperature metal seats.
The new 800 ISO valves offer an ISO 5211 actuator interface with an extended neck to allow for pipe insulation, a smooth uninterrupted retainer and closed bottom for improved safety and leak prevention.
Xomox centric design Resilient Seated Butterfly Valves are used in demanding service applications and are a reliable, low maintenance shut-off and control valves.
These valves are designed for use in gas and liquid pipelines, to a maximum working pressure of 230psi. They are equipped to handle an operating temperature range of -30 degrees F to + 300 degrees F. An economical alternative to plug, gate, and ball valves.
XOMOX Series 7000 Resilient Seated Butterfly Valves
Stem Configuration: Provides positive attachment for handles or actuators. (Double “D”, 2" - 24" )
Shaft Weather Seal: (Below bushing on some models.)
Actuator Flange: Accommodates all types of actuators: handles, gear operators, electric actuators, and pneumatic actuators. (2" - 24" per ISO 5211)
One-Piece Thru Shaft: Ensures dependability and positive disc positioning.
Bushings (4): Stem bushing reduces torque and isolates the stem from the valve body, preventing seizure of the stem due to corrosion in the stem journal.
O-Ring: Helps prevent stem leakage.
Seat Face: Negates need for flange gaskets.
Smooth Finished Disc Flats: These “mate” with seat flats to give a highly efficient seal; prevents leakage into shaft areas.
The body lining and disc are the only components of the valve that come into contact with the line medium. These components come in a wide variety of materials which resist degradation from the majority of line media.
Permanently Tight Closure
Xomox Series 7500 Butterfly Valves close liquid and gas tight in both flow directions.
The disc is pressed with a defined constant compression over the entire disc circumference, into the elastic body lining. The power transmission between disc and spindle is effected via a
square drive and provides for an axial movement and self centering of the disc, which prevents overstress and wear of the elastomer.
Suitable for Vacuum Service
The replaceable body lining consists of a firm back-up ring onto which the elastic seating material is vulcanized, thus creating stability of the seat which prevents deformation of the elastomer during closing.
The bond between elastomer and back-up ring is strong enough to enable the valve to be used with high flow rates and for vacuum service.
