Introduction
The Masoneilan 39004 Series High Performance Butterfly Valve
(HPBV) is a double-offset design, suitable for a wide range of
services, including oxygen, chlorine, sour gas, vacuum, and
steam applications. Bubbletight shutoff is provided throughout a
wide range of operating conditions.
Suitable for both modulating and on/off services, the 39004
butterfly valve is easily automated with your choice of manual
operators, electric and pneumatic actuators, positioners,
and controls.
The 39004 HPBV is available in a Fire Safe model qualified to
API 607 4th Edition and BS 6755 part 2.
Additional information about the Masoneilan 39004 HBPV
– including application data, engineering specifications, and
actuator selection is available from the GEA20232 Technical
Specifications as well as your Baker Hughes sales representative.
1. Installation
Special instructions for Fire Safe valves appear on page 6.
1. The 39004 Series High Performance Butterfly Valve is
designed to be mounted between ASME flanges. When
the valve is open, the disc will extend into the pipe on both
sides of the valve – further on the body side than the seat
retainer side of the valve. Piping must be large enough to
allow the disc to clear the pipe. The charts below show
the minimum pipe ID allowable, and standard pipe IDs. In
general, Class 150 valves will clear Schedule 40 pipe, and
Class 300 valves will clear Schedule 80 pipe adequately.
Class 600 will in general clear Schedule 80 sizes 3, 4, and
6; and Schedule 100 in sizes 8, 10, 12, 14, and 16.
2. If handle or actuator has been removed, do not rotate disc
beyond full open or closed position – this could cause
damage to sealing surfaces. (NOTE: The 39004 Series
valves are equipped with stops to prevent over closure.)
The valve is opened by turning counter-clockwise, closed
by turning clockwise. The double “D” flats or keyway at the
top of the stem is parallel to the disc edge.
3. For maximum service life, install the valve with the seat
retainer upstream. Positive shutoff will be obtained with the
valve in either position; however, installation with the seat
retainer upstream will give longer service life, especially in
erosive services.
4. With the disc in closed position, carefully center valve
between flanges. Guide holes (wafer pattern valve) or
tapped holes (lugged valves) match ASME pipe flanges and
assist in positive alignment.
5. Use standard torques when bolting valve into the line. The
seat is sufficiently compressed by the seat retainer, and
additional force from flange bolting is not required.
6. Gaskets should conform to the requirements of API
Standard 601, Edition 3 for ASME/ANSI B16.5 class flanges.
Spiral wound gaskets, such as Flexitallic CG or CGl series,
conforming to ASME/ANSI B16.20 are acceptable.

Minimum Inside Diameter of Pipe with the Recommended
Clearance
Nominal Inside Diameter of Pipe
NOTES:
1. Minimum l.D. of pipe with recommended clearances (per API 609) have been
calculated by adding the minimum I.D. with zero clearance to a minimum
recommended diametric clearance for each pipe size.
2. These charts assume that the pipe is on the body side of the valve and that
the pipe is perfectly centered. The seat retainer side of the valve will always
have more clearance than the body side.
3. A minimum of 1/16" thick gasket is used between the pipe flange and valve
body face.
4. When using a pipe whose l.D. is smaller than the recommended minimum
inside diameter of pipe with adequate clearance, a chamfer of 45° should be
provided on the end of the pipe so that it clears the disc.
