1 Eccentric style, round ported plug valves F80 - valve sizes DN 80-0 F83 - valve sizes DN Features The resilient plug provides tight shut-off without sealing lubricants. The plug valve utilizes a corrosion resistant welded nickel seat. One piece cast iron plug provides superior strength and no deflection. Corrosion resistant permanently lubricated stem bearings top and bottom. Bolted one piece Cast Iron top housing for high strength and easy maintenance. Top and bottom grit excluders to prevent the ingress of contaminants into the bearings. Flanged end connections available as standard. Full round port offers less flow resistance. Eccentric plug action eliminates plug drag on the seat while cycling. As the plug moves off the seat, plug-seat contact ceases at about open through the fully open position preventing wear and deformation of the resilient plug sealing surface. General application Keystone ballcentric valves control the flow of materials such as pulp and paper stock, industrial slurries and sludges, raw sewage, raw, activated and digested sludge, industrial and municipal effluents, sewage gas. Typical applications include use on digesters, industrial slurry transfer lines, power plant ash handling systems, clarifiers, sludge collector systems and activated sludge reactors.

6 Anticipated seating AND unseating torque values - Nm (fully rated) Shut off pressure kpa/(bar) Valve Normal service size DN (0) (3) (6) (.3) (12) The charted seating and unseating torques are the sum of all friction and resistance for opening and closing of the valve against the indicated pressure differential for normal service. 2. Normal service: Clean liquid service at temperatures between minus 18 C to 0 C with no internal deposition or chemical attack. Operated a minimum of once per day. 3. The relationship between values are linear, therefore you can interpolate between nominated values.. The effect of dynamic torque is not considered in tabulation.. In sizing operators it is not necessary to include safety factors. For conditions that vary from those noted, apply the following Application Factor Multipliers; Line media - Dry service with abrasives, cement x 3.3 Dry gas other than air x 2. Dry air x 1.7 Liquid media other than water x 1.2 Lubricating oil x 0.7 Frequency - Operated less than once per day x 1.1 Condition - Corrosive seating surfaces or x 1. deposit buildup Chemical attack: Consult factory Example: A DN 10 Figure 80 valve is to be used in a clean water application. The line pressure is 00 kpa ( bar) at 80 C. The valve may only cycle twice per month. 1. Using the fully rated torque values table base torque value for DN 10 at 00 kpa ( bar) = interpolating between values = 383 Nm 2. Find torque value at zero kpa = 2 Nm Subtract = 138 Nm 3. Multiply zero pressure torque value by Application Factors Operated less than once per day = x x 1.1 = 270 Nm. Add the difference between zero pressure and line pressure, as per step 2 to the value determined in step = 08 Nm The new torque value for this valve, specific to the actual service conditions is 08 Nm. To apply the as noted Application Factor Multipliers: 1. Find the base torque value by selecting the required valve size from the left hand column and read across to the intended line pressure column. Note the torque value. You can interpolate between line pressure values. 2. Find the zero pressure torque for the same valve on the same row and subtract this zero pressure torque from the value in step Multiply the zero pressure torque value by the expected Application Factors.. Add the difference between the zero pressure torque and the line pressure torque (value of step 2 plus value of step 3) to give the new torque value specific to the actual service conditions. 6
