INSTALLATION GUIDE FOR NIBCO BUTTERFLY VALVES
I. SHIPMENT & STORAGE
NIBCO butterfly valves are individually boxed thru the 12" size. The 14" through 48" butterfly valves are shipped individually with the
faces covered using cardboard or plywood to protect the flange sealing surfaces.
The disc is shipped in the nearly closed position to protect the sealing edge and prevents the liner from taking a temporary set. The
stem bushings and disc edge have been coated with a factory-applied lubricant to prolong storage and service life.
Valves may be shipped or stored in any position. Storage should be limited to 10 years indoors with a temperature range of 40º F to
90º F.
II. BUTTERFLY VALVE INSTALLATION GUIDELINES
NIBCO butterfly valves are bi-directional and may be installed with flow in either direction.
Flanged, lug and wafer style valves are designed and suitable for installation between ANSI Class 125 or 150 flanges. Cast iron
flat-face, steel raised-face, both slip-on and weld-neck, and bronze or plastic flanges may be used (See Table I below). Because of
the unique seat design, NIBCO (2"-48") butterfly valves do not require the use of flange gaskets and can be used for dead end service
without a downstream flange. Grooved style valves connect to metallic pipe of IPS per AWWA C606.
The valve can be installed in any horizontal or vertical position. If a choice of stem positions exists, the valve should be installed with
the stem in the horizontal position; this will minimize seat wear by distributing the stem and disc weight evenly. Also, if the media is
abrasive, the horizontal stem position is highly preferred.
These valves have been designed so that the disc, in the open position, will clear the inside diameter of schedule 40 and 80 steel pipe.
Care should be taken when installing a butterfly valve adjacent to lined pipe, as-cast fittings, or schedule 80 plastic pipe. In some
cases the disc in the opened position will interfere with the adjacent component.
Butterfly valves should be installed a minimum of six (6) pipe diameters from other line components. This is not always practical
but it is important to design in as much distance as possible. Interference may occur when valves are installed directly to the outlet
flange of a swing check, silent check, or reducing flange. Check valve and butterfly valve combinations are very popular; normally a
short spool piece is required between the valves.
When using a valve with gear operator attached, it may be desirable to have the hand wheel positioned to allow easy access, or
for use of an optional adjustable sprocket rim (chain wheel) for remote operation. Before valve installation, please review Gear
Operator Installation and Handwheel Positioning section on page 3 of this booklet. These instructions illustrate how to orient the
gear operator handwheel position in relation to the valve body and piping system. Pre-planning may save from having to remove a
"just installed" valve and re-installing in another orientation.
