GE’s Masoneilan 39003 Series High Performance Butterfly Valve
(HPBV) is a heavy duty automatic throttling control valve that
incorporates the two basic features of the HPBV types. These
features differentiate the the Masoneilan* 39003 Series HPBV
from the conventional swing-through butterfly valve in regards to
sealing method and operational characteristics. Specifically, the
two basic features are: (1) A PTFE, RTFE, or metal seal ring instead
of a liner, and (2) The employment of double offset (eccentric
operation). Each of these features contributes to the improved
performance of HPBV’s compared to conventional butterfly valves.
The use of a seal ring (PTFE, RTFE, or metal) eliminates the inherent
problems of high sealing forces, due to interference fit, and the
resultant high wear rates due to scraping and scuffing of liners.
Also, due to the design of the seal itself, which is a dynamic pressure-assisted member, ANSI Class VI shutoff rates are available
throughout the full range of ANSI Class 150, 300 and 600 ratings
(soft-sealed constructions only).
The double offset (eccentric) operating principles of both seal offset (the seal ring centerline is offset from the shaft centerline – see
Figure 1) and shaft offset (the shaft centerline is offset from the
valve centerline – see Figure 1) allows the disc to get off the seal
quickly due to the camming rotation with respect to the valve/seal
centerlines. This results in minimal sliding (friction producing) contact between the disc and the seal ring with complete separation
after only a few degrees of rotation.
The overall characteristics of the Masoneilan* 39003 Series Valve
are listed below:
• Long seal life – Offset (eccentric) operation gets the disc off the
seal quickly, minimizing sliding contact and friction, resulting
in reduced seal wear and lower breakaway and seating torque
requirements.
inates disc-to-seal friction throughout the operating range
resulting in fast response to input signals. Also, the disc tends to
move in the direction of flow, assisting the valve and actuator to
maximize the allowable operating pressures.
• Excellent flow characteristics – the offset (eccentric) disc design
provides an approximate equal percentage flow characteristic
through its full travel of 90° rotation yielding a Cv ratio of 100:1.
• Extra heavy shafts with keyed ends for actuator mounting –
precise and accurate positioning without lost motion or back-
lash.
PTFE-lined low-friction bearing – Reduces operating torque and
promotes fast response to valve and actuator action. The triple
bearing support of the shaft prevents deflection of the shaft due
to side-loading.
Field replaceable components – Unlike most competitive valves,
shaft and disc need not be purchased as a set. The Masoneilan*
39003 Series Valve uses tapered pins to attach the shaft and disc
positively, yet provide component interchangeability.

Features
GE’s Masoneilan 39003 Series HPBV includes unique valve seal designs for
metal, soft seal, and fire-safe configurations.
Metal Seal Design
The metal seal design incorporates an Inconel seal for higher tensile strength,
a 300 series stainless steel back-up ring in the seal cavity for axial seal
support, and a disc that is case hardened by nitriding.
The Inconel seal, by its dynamic and flexible design, applies enough force per
linear inch against the disc edge (Rockwell Hardness of C66 to C70) to obtain
an optimum sealing characteristic while controlling the loads between the
metal surfaces.
The metal seal design can be utilized for temperatures up to 900˚F, in
compliance with ANSI B16.34 pressure/temperature specifications. Leakage
is rated at Class IV per ANSI FCI 70-2.
Soft Seal Design
The soft seal design provides a bi-directional bubble tight shutoff (zero
leakage) through the use of a patented seal. This unique seal design creates a
self-energized seal in vacuum-to-low pressure applications.
Under higher pressure conditions, the seal is also designed to confine and
direct movement of the soft seal against the disc edge, up to the full ANSI
Class 150, 300 and 600 Cold Working Pressures.
The soft seal is designed for high services with minimal wear and low torque.
Seal replacement is a simple procedure requiring no special tools.

Fire-Safe Seal Design
The fire-safe seal design incorporates two patented seals which function
together to seal off pipeline flow. In normal operation, the soft seal provides a
bi-directional “bubble tight” shutoff (zero leakage); the metal seal provides bidirectional shutoff in the event of a fire, in conformance to industry fire-safe
requirements.
With little or no pressure, the fire-safe seal creates a self-energized seal
against the disc. Higher line pressures act on the geometry of both seals
to dynamically load them against the disc, creating higher sealing forces in
either direction.
The metal seal is made of Inconel material which is shaped by a proprietary
hydroforming process into its unique, patented design. Stainless steel outer
bearings are included for post-fire disc and shaft alignment. Fireproof
packing is used to prevent external shaft leakage.

Pressure/Temperature Ratings
Soft and Fire-Safe Seal
As temperature increases, the pressure retaining capability of
materials decreases. The graph below illustrates the pressure/
temperature ratings for ANSI Class 150, Class 300 and Class 600.
The heavy lines define the ratings of the carbon steel and stainless
steel valve body (or “shell”) in conformance to ANSI B16.34. The
shaded areas define the ratings of the PTFE and RTFE Seal materials (Soft Seal).
Seal ratings are based on differential pressure with the disc in the
fully closed position.*

End Seal Variation
The ANSI 150 14” through 24” sizes feature a two-piece shaft
design. The lower shaft utilizes an end seal in the body to prevent
external leakage. The component parts include an end seal, an
end cap and end cap bolts.
Lower Packing Variation
The ANSI 150 30” through 48”; ANSI 300 14” through 30”; ANSI
600 10” through 16” sizes feature a two-piece shaft design which
utilizes a lower packing seal in the valve body to prevent external
leakage. The component parts are of the same design used in the
packing assembly in the top of the valve body neck.

Allowable Pressure Drops
GE has created a simple actuator sizing and selection program,
which allows for quick and accurate actuator sizing based on
the specific service conditions. This program is designed to run
in Microsoft® Excel®, and is available from your local GE sales
representative.
The opening screen of the sizing program is shown below.
Operating variables can be selected from a number of pulldown menus. The program will then provide an actuator
recommendation, along with calculations for the required torque
(with safety margins) for valve seating, unseating, and throttling
conditions.
This program covers standard product construction only. Please
consult with your local GE sales representative, or with the factory,
for applications and conditions not covered by this program.
