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



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

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



Position of Sylax

removal.



Mounting wafer style Sylax

that extend through both flanges



Mounting lug style Sylax

are not recommended.



During installation verify:



The piping alignment to Sylax



The Sylax

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 seat / liner flange face has a molded in o'ring which provides all the valve to flange

sealing necessary.



The Sylax

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



Recommended routine inspection checks should include:

Verification by visual inspection that valve seat and flange sealing surfaces are in good 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.

NOTE: for size and quantities of bolts see table

butterfly valve selected is correct for the application.

butterfly valve disc outside diameter is not greater than piping/flange inside diameter.

butterfly valve can be bi-directional.

butterfly valve in piping system should allow for ease of operation, maintenance and

butterfly valves to the pipeline flanges can be done with either bolts or studs

butterfly valves to the pipeline flanges should be done with bolts only. Studs

butterfly valve is correct.

butterfly valve disc is open partially inside the valve body. Disc should not be in full

butterfly disc is interference free from piping components. While flange bolting is

butterfly valve disc should be in open position for initial system pressure testing.
