  • Since 1914, Keckley engineering andmanufacturing has been working forindustry and commercial building installations worldwide. Keckley Float and Lever Valves excel in theirconstruction and performance.

    With the purchase of Klipfel Valves Inc. in 1962, there was a combining of engineering talents and features of both valve companies resulting today in this complete line. Float Valves are actuated Lever Valvesdesigned to control the level

    of liquids. Lever Valves are designed to control the flow of liquids, gases or steam. This can be done by manual operation, float boxes ormechanisms, electric motors or other actuators through linkage to the lever of the valve.

    The No. 27double seated float valve is the typemost widely used for the automaticcontrol of the supply of liquids to anopen tank where dead-end closing isnot essential and valve inletpressures are normal. Manythousands are in use on large andsmall water, oil and chemical storage tanks in all types ofindustries.Where a drop-tight closing float valve, or a valve for higher thanordinary pressure is required, one ofthe single seated valves, describedon the following pages, should beselected. The maximum inletpressures for the sizes of the No. 27valve are shown in the table on theopposite page.The No. 62 lever valve is the samevalve minus the float, float rod androsette. It may be operated by a floatinside a closed tank or float cage; byhand or electric solenoid as a quickopening valve; and wherever adouble seated sliding stem valve isrequired.

    These valves are allmetal, simple in operation, sturdy inconstruction and of the bestmaterials and workmanship. Adouble seated inner valve, asillustrated, is standard. Both angleand globe pattern bodies areavailable in all the sizes. Thestandard valve can be adapted tonearly any installation.The swivel yoke, which supports thelever, can be turned and secured atany angle. The length and angle ofthe float rod can be adjusted at therosette so that the valve can beeasily adapted to various locations.

    In sizes 112 inch andsmaller, the No. 27 and No. 62 valveshave bronze bodies and trim withintegral seats. In sizes 2 inches andlarger, the standard bodies are castiron with bronze trim and removableseats. Stainless steel trim can alsobe supplied. All iron, all bronze andall stainless steel valves can besupplied at extra cost in many sizes.

    As ordinarily assembledand used as a filling controller, theinner valve in the No. 27 rises andopens as the float drops with thewater level. With the lever reversed,the float and inner valve move in thesame direction so that the valve willopen on level rise and can be usedas a drainage controller.In the same manner, the No. 62valve may be assembled for eitherdirect or reverse movement.

    A float valve when usedon a water tank installation is bestlocated near the surface of the waterwith the float where it will be leastdisturbed by waves. The dischargepipe extending below the surfacehelps to prevent waves. Wheresanitary regulations forbid the use ofsuch a discharge pipe because ofthe possibility of siphoning out ofthe tank, the discharge may flowinto a funnel and perforated pipe.The angle pattern will avoid theneed for an elbow

    Note that the inlet of the No. 27valve is at the side of the anglepattern body.

    The valve stem should be verticalto avoid friction and wear on theinner valve sliding on its side. Thevalve will operate just as well if in-verted, but the lever must be re-versed. If space limitations requirethe valve to be installed with stemhorizontal in a vertical pipe, a leverbent 90 can be supplied. The valvemay be submerged, if desired.

    The No. 62Lever Valve is adapted for manualcontrol of steam, water and air lineswherever a quick acting doubleseated valve is required, but whereperfectly tight closing is notessential.

    It is widely used on feed waterheaters and on open and closedtanks and operated by an internalfloat such as the No. 20, shownon page 10. It may also beoperated by an electricsolenoid, diaphragm motor,or hydraulic cylinder.

    All sizes are fittedwith swivel yokes, so that the levercan be turned to any desireddirection. The lever can be reversed

    to close the valve when the longerend is lifted. The counterweight isused on either end to balance leversor rods which may form part of theoperating mechanism. Standardconstruction includes double seatedinner valve not designed for tightclosing applications.

    NO. 77 GLOBE

    The No. 7 and77 pilot controlled float valves arerecommended when tight closing isessential. They are commonly usedto maintain a water level in an opentank. They are best suited for cleanliquids not injurious to neoprene,leather or brass parts. Standarddesign temperature is 125F. Forhigher temperatures up to 350F, theneoprene disc in the No. 7 orneoprene disc and leather cup in theNo. 77 are replaced by teflon parts.

    Referring to thesectional views on page 8, the innervalve consists of a hollow bronzepiston, somewhat larger in diameterthan the seat bore, and carrying thedisc holder. The composition discmay be replaced when worn. Thesoft disc will accommodate itself togrit and wear and still close tightwhere a metal to metal constructionwould leak.

    The piston slides in a stationarybronze cylinder attached to the coveror body. The pilot port is opened andclosed by the end of the stem whichis moved by the lever. A pin throughthe stem at its lower end permits theinner valve to be lifted by the stem.

    The guide yoke, with the lever andfloat, can be turned and secured atany angle. The angle and length offloat rod can be adjusted at therosette.

    In the No. 7 valve, madein sizes 2 inches and smaller, waterfrom the inlet enters the spaceabove the piston through a smallhole in the piston head. While thepilot port is open, this water escapesfreely through the hollow valve postto the outlet. The excess pressureunder the piston, in relation to thepressure above it, and the weight ofthe float hold the valve open.

    On closing the pilot port, the waterpressure above the piston quicklyrises to equal and balance the inletpressure under the piston. There-upon the inlet pressure above thedisc holder closes the valve. Noleather cup is required.

    The disc closes in the direction ofthe flow through the No. 7 valve. Inthe larger valves and for the higherpressures, the pull of the water inpassing through the valve seat maycause the valve to close suddenlyfrom a nearly closed position. For

    this reason, this valve is not made insizes above 2 inches.

    In the No. 77 valve, made in sizes 2inches and larger, the inlet pressureis under the disc. Water enters thechamber above the piston throughthe strainer and the central anddiagonal passages. If the pilot port isopen, this water escapes freely tothe valve outlet, so that the inletpressure under the disc opens thevalve. When the pilot port is closed,the water pressure above the pistonquickly rises to equal the inletpressure under the disc and, due tothe larger piston area, the innervalve is moved toward the seat.

    The disc closes against the inletpressure and sudden closing cannotoccur in the No. 77. However, thisvalve requires the piston to be fittedwith a leather cup, the friction ofwhich may cause sluggishness onlow inlet pressures.

    Maximum inlet pressures for boththe No. 7 and No. 77 are shown inthe table on the next page.

    These singleseated, internal pilot type levervalves are adapted for operation byan enclosed float (page 10)or by hand, solenoid, diaphragmmotor, or other means, wherever atight-closing, quick-acting, easilyoperated valve is required.

    The lever valves on thispage have the same internalconstruction and operate in thesame manner as the float valvesdescribed on pages 7 and 8. Theyare also adapted to the same pres-sure and temperature conditions asthe corresponding float valves.

    No. 73 valve in sizes 112inch and smaller have bronzebodies and integral seats, screwedends only. The 2 inch No. 73 and allsizes of the No. 773 have cast ironbodies, with renewable seats,screwed or flanged ends in sizes 2 inch to 3 inch inclusive, flangedends only above 3 inch. All sizes ofboth valves have bronze trim andrenewable composition discs.

    They are suitable for water andother ordinary liquids. The operatingrod may be attached to either end ofthe lever with the counterweightlocated as required.

    The No. 73 Single Seated Lever Valve is thesame as No. 7, shown and described onpages 7 and 8, minus float, float rod androsette, and plus a counterweight.

    6" or 8" FloatsCast Iron Body With Ball Bearing Stuffing Box

    Float Boxesare used in connection with closedtanks where fluctuation of theliquid level in the tank is thegoverning factor in the control ofthe lever valve, signal switch,motor or other equipment. Theentire unit is mounted outside thetank where it can be easilyinstalled, adjusted, inspected andserviced.

    By placing the Box in the samehorizontal plane as the tank liquidlevel with equalizing connectionsabove and below the level and thevalve suitably linked to the Box,the tank level may be auto-matically maintained whether theflow is into or out of the tank.

    Typical applications are with aNo. 62, 73 or 773 lever valveused as a level controllerfor hot or cold water.

    The packing boxhas outboard ball bearing withbolted gland reducing friction andwear to a minimum, the rotarystem is stainless steel. The floatrod is brass when used with a 6inch float and galvanized pipewhen used with an 8 inch float. Agauge glass and bracketed leverand counterweight completes theUnit.

    Equalizing pipe connections are1" screwed on the Box with the6" float, 112" standard flanged orscrewed connections on the 8"Box. Cast iron Float Boxes aresuitable for pressures up to 250psi and maximum temperaturesof 406F.

    Various types of switchesavailable are mercury tube switch,single pole snap switch and theexplosion proof mercury tubeswitch. Rating of all switches is 10amperes at 110 volts or 5amperes at 220 volts AC or DC.

    The maximum capacity of a float orlever valve depends on its size andon the pressure difference or drop between the inlet and outlet when the valve is wide open. It isrecommended that a valve beselected having 50% to 100% more

    capacity than the normal demand.For example, if the normal require-ment is 100 gallons per minute, avalve having 150 to 200 G.P.M.capacity should be selected. This will result in less variation in waterlevel, and provide reserve capacity

    in case of low water pressure orunusual demand. The maximumcapacity is the product of the flow per square inch of port area (OrificeCapacity) multiplied by the equivalent port area of the valve(Capacity Factor).
