SHIPMENT / STORAGE / INSTALATION:

Sylax ® butterfly valves disc should be opened no more then 4 to 5 degrees during storage or
transportation. This is to protect the disc edge from damage.

Sylax
®
butterfly valves should be stored in a clean, dry place away from uv light.

Prior to installation verify:
 That the Sylax ® butterfly valve selected is correct for the application.

That all sealing surfaces are clean, and free from debris.
 That all scale, debris, foreign materials are removed from piping system.
 That valve operator (lever, gear or actuator) is properly secured to valve.
 That Sylax ® butterfly valve disc outside diameter is not greater than piping/flange inside diameter.
If it is valve will not open properly and you may “jam” disc inside piping/flange damaging valve
disc.

The Sylax ® butterfly valve can be installed in any orientation in pipeline.

Flow through the Sylax ® butterfly valve can be bi-directional.

Position of Sylax
®
butterfly valve in piping system should allow for ease of operation, maintenance and
removal.

Mounting wafer style Sylax ® butterfly valves to the pipeline flanges can be done with either bolts or studs
that extend through both flanges

Mounting lug style Sylax
®
butterfly valves to the pipeline flanges should be done with bolts only. Studs
are not recommended.

During installation verify:
 The piping alignment to Sylax ® butterfly valve is correct.
 The Sylax
®
butterfly valve disc is open partially inside the valve body. Disc should not be in full
closed position when tightening flanges. This allows rubber seal to self position for proper seal to
disc interaction.
 A flange gasket is not used between the Sylax ® butterfly valve and the pipe flange. The Sylax ®
butterfly valve seat / liner flange face has a molded in o’ring which provides all the valve to flange
sealing necessary.
 The Sylax ® butterfly disc is interference free from piping components. While flange bolting is
finger tight, open disc slowly to check for interference. If no interference return disc to partial
open and finish tightening flange bolts in a crisscross pattern.
If interference occurs check for
piping misalignment. After realigning piping flanges recheck for interference.

After installation Sylax ® butterfly valve disc should be in open position for initial system pressure testing.

Recommended routine inspection checks should include:
 Verification by visual inspection that valve seat and flange sealing surfaces are in good condition.
 Verification that the valve operator is in working condition.
 After inspection/maintenance verify that valve is opening and closing smoothly.
 After inspection/maintenance verify that valve is leak tight in closed position.

Wafer and lug style butterfly valves provide the same working performance. However the lug style, only
can be used for “ bi-directional dead end ” service, however, pressure rating may be de-rated.
