Butterfly Valves
Omni Seal
5000
Series Butterfly Valves
Our 5000 series Butterfly valves are manufactured in accordance
with the
specifications from MSS SP 67, Manufacturers Standardization
Society
and API-609, American Petroleum Institute, latest revisions.
Both Lug and Wafer style valves are designed for ANSI 125/ 150 lb.
class
flanges and are rated at 200 PSI WOG service.
Omni Seal Butterfly Valves make an excellent choice by combining
the
balance of an economical valve with the performance you expect in
a
commercial, HVAC and an industrial butterfly valve.
Product Features
|
|
 |
100% Bidirectional factory tested valve product |
|
|
|
Extended neck design for applications that require insulation |
|
|
|
One piece uni-body construction of cast iron designed to accommodate both ANSI and DINF flanges |
|
|
|
Integral mounting flange will accept all styles of hand levers, manual gear operators |
|
and pneumatic or electric actuators |
|
|
|
2 piece stainless steel plate functions not only as a bushing but as a retention plate for |
|
possible blow-out |
|
|
|
The liner is constructed by bonding an elastomer seal to a split, rigid phenolic backup |
|
ring which forms the outside periphery of the seat |
|
|
|
This cartridge design helps prevent the possibility of blowouts and provides for easy |
|
replacement. The ribs on the outside elastomer provide an
interface seal with flanges |
|
|
|
Two piece shaft design eliminates the need for bolts or pins to attach shaft to disc, |
|
thereby removing potential leak path of media. Two piece shaft
design allows for a |
|

|
Field replaceable seats are a standard design feature |

Multi Purpose IVEX Range
The inter valve IVEX-Range is based on a unique quarter-turn
design.
The double offset shaft and disc configuration to the seat
together with
the advanced high technology seat systems brings in a multipurpose
IVEX-butterfly range.
Main Design Features
Double offset disc design.
At the initial point of disc opening, the double offset disc
provides a
cam-like action. Thus preventing excessive seat wear and creating
the
possibility for frequent operation.
Sizes range from 2" to 48"
Class 150 & 300 lbs.
Body design can be lug (single flanged) and wafer design
Asbestos free design
Metal header prevents cold flow of packing and centers the disc
exactly
in the seat (trust bearing)
Metal to Metal seat for high temperature service
Reinforced PTFE seat-ring with secondary metal seat for fire-safe
protection
Seat removal without disassembly of shaft and disc
Body insert protects seat from abrasion and erosion
Grafoil seal-ring & packing
Shaft bearing in PTFE or AISI 316
2 Piece stem for extra flow
The IVEX Valves will be supplied with an actuator bracket
according to
ISO 5211, which allows replacement of the stem seals without
removal of
the actuator
Power Seal Valve Produces the IVEX range in three main executions:
IVEX T: PTFE Seat System
IVEX F: PTFE Metal seat system, bidirectional sealing and fire
safe design
IVEX M: Metal to metal seat system for high temperature service
PTFE-Seat system
In the preferred flow-direction, the PTFE- Seat system will bring
its
optimum performance. In this design, the line pressure act as a
positive
force in the seat-system even at fluctuating working condition.
The seat
ring is well protected by the valve-body, thus preventing
distortion at a
negative, non-preferred flow direction.
PTFE-Metal Seat system
Bi-directional sealing and fire safe design
Bi-directional
The primary PTFE- seat ring will be replenished with a secondary
metal
back up ring. This metal seat provides a mechanical load to
energize the
PTFE- seat. In combination with the line pressure a Bi-directional
sealing
against the design pressure is obtained.
Fire Safe
After a fire, when the PTFE- seat ring has burned away, the
secondary
metal seat gives bi-directional sealing. This sealing system meets
the
fire test requirements API 607 and BS5146.
Metal to Metal Seat
High Temperature service
The primary metal seal enables this execution to be used up to 670
grade C. Seat- rings available are stainless steel ANSI 316
L-chromium
plated, (maximum allowed temperature: 310 grade C) and Inconel 625
(maximum allowed temperature: 760 grade C). As a result the IVEX
M-Metal to Metal range meets the full pressure temperature rating
according to the ANSI class 150 and class 300 rules.
