Basic Formulas for obtaining Cv-Value

Flow coefficient for ACE Butterfly Valves

Rated flow coefficient (Cv) is a number which represents a valve’s ability to pass flow.The bigger Cv, the more flow can pass the valve with a given pressure drop. Rate Cv means the volume of water in unitedstates gallons per minute that will pass through a given valve opening with a pressure drop of 1 pound square inch.(Waterat temp=60DEG.F) A Cv of 1900 means a valve will pass 1900gpm of 60 F water with a dp of 1PSI.

The relation between Cv and Kv, expressed in the above mentioned unit of measure are as followsCv=1.16kv

Formula 1FLOW RATE LBS/HR(Stem or Water)

Where :dp = pressure drop in PSIF = flow rate in lbs./hr.

= square root of specific volume in ft. /lb.(downstream of valve)

The torques listed are applicable to water, sea water, lubricating type of hydro carbons and most media at temperature 0~80 (32~180 F).The operating speed of the actuator must be considered in order to avoid water hammer when the valve is closed in junction with Liquid.

Method for Carrying & Keeping

How to Install Butterfly Valve

Centering & Flanging of Valve

RIGHTBolts spanned, disc edge with inbody face-to-face.No disc edge damage,propersealing allowed

Be careful not to scratch Disc and Seat ring.The flange must be protected by plywood or other things when carrying valve.

Valve must not be shocked and shaken too much.(It may cause the breaking neck, lever, handle, and body)

Valve is recommended to be kept and carried under the condition of opening.

The suitable temperature is over -10 and humidity is 60% while keeping valve.

In keeping Valve, must check the operation once per three months.

Aligning of Flange bolts

WRONGPiping misaligned:Result-DiscO.D. touches pipe I.D. causing discedge damage. Increased torque &leakage.Seat face, seals improperly withoutengagement

RIGHTPiping aligned properly when boltstightened, disc in full open position:Result-disc clears adjacent pipeI.D., seat face seals properly, noexcessive initial torque.

WRONG CORRECT

WRONGDisc in closed position:gasketsused:Results-Seat distorted andover compressed causing highinitial unseating torque problems
