KF Series WB Design Features 1 Anti-Blowout Stem Design Stem seal integrity is achieved by the use of three o-rings (or two o-rings and a graphite gasket). Upper o-ring and graphite gasket can be replaced with the valve in line and under pressure.
2 Antistatic Device A spring loaded ball between the trunnion and the ball or between the stem and the bonnet permits electrical continuity between all valve components.

3 Emergency Sealant Injection System Special sealants may be injected thru fittings that are located on the adapter flanges to restore sealing integrity if seat sealing surface is damaged. A second internal check valve provides backup to the fitting.
4 Internal Stop Integral internal stop is a permanent reference designed to indicate open and closed positions. It may be considered as a secondary stop ensuring control over ball rotation and permitting accurate mounting of an actuator or gear operator.

5 Stem Sealant Injection The sealant injection system located on the bonnet can be utilized in case of emergencies, o-ring damage, or if stem leakage occurs.
6 Heavy Duty Bearings Trunnions are supported by heavy duty Teflon® coated steel bearings. Thrust load on the ball is supported by large trunnions mounted within captured trunnion blocks, resulting in low operating torque and low seat wear.

KF Series WB Technical Seating Features Double Piston Seat Design Upstream Seat Line Pressure acting on the seat area (A1) does not equalize against the line pressure acting on the seat area (A2). The difference in the area (D1) times the line pressure creates a “piston effect” force which pushes the seat against the ball surface resulting in a tight effective seal. Downstream Seat When the body cavity pressure is greater than the downstream pressure, the body cavity pressure acts on the seal area (A4). The net pressure difference, acting over area (D2), pushes the downstream seat tightly against the ball creating a positive seal. The Ultimate Benefit of Using the “Double Piston Seat” Design In case of upstream seat leakage, the downstream seat maintains a pressure assisted tight shut off by sealing against the ball surface. Double Block and Bleed The double block and bleed condition is available in all seat design configurations. When the ball is in the closed position the body cavity pressure may be drained down to ‘zero’ by opening the bleed valve and draining the fluid by removing the drain plug. Each seat works independently assuring tight shut off seal against ball on the upstream and downstream side.

Calculating Pipe Wall Thickness To find the “Pipe Wall Thickness” for buttweld valves, subtract the Inside Diameter from the “Pipe Outside Diameter” for the appropriate size, listed to the left. Then divide the outcome by two (2). Example For an 8" valve with an 8.625 Inside Diameter: Outside Diameter Taken from Chart at Right: 8.625 Inside Diameter Given by Customer: 7.981 8.625 - 7.981

22 Code 22.00 .375 33 — — 0.500 39 1.125 62 — — — —
Pipe Outside Diameter (O.D.) Once you have determined the “Pipe Wall Thickness”, find that number in the chart above. The two-digit number to the left should then be used in the “Pipe Wall Thickness” digits of the valve Assembly Part Number. In this example that would be 28.

Method of Calculating Flow The Flow Coefficient “Cv” of a valve is the flow rate of water (gallons/ minute) through a fully opened valve, with a pressure drop of 1 psi across the valve. To find the flow of liquid through valve from the Cv, use the following formulas:
Liquid Flow QL = Flow rate of liquid (gal./min.) ΔP = Differential pressure across the valve (psi) G = Specific gravity of liquid (for water, G=1)
P G
QL=Cv
Gas Flow Qg = Flow rate of gas (CFH at STP) P2 = Outlet pressure (psia) g = Specific gravity of gas (for air, g =1.000) P2 P g
Q g= 61Cv
