Applications
Automatic Distributing Valve Assemblies are used to pressurize
multíple zone distribution systems including textile filters, sand
filterc and drainfields.
General
orenco's Automatíc Distributing Valve Assemblies are
mechanically operated and sequentially redirect thepumpl flow to multiple zones or ce[s iñ a distribution
field. Valve actuation is accomplished by a combination
of pressure and ftow. Automatic Distribúting Vatve
Assemblies alfow the use of smaller horsepıwer pumps
on large sand filters and drainfields. For example, a lárge
community drainfield requiring 300 gpm can use a six_liñe
Valve Assembly t0 reduce tne pump-itow rate requiremenl
to only 50 gpm.
orenco only warrants Automatic Distributing Valves when
used in conjunction wíth High-Head Efftuenipumps with
Biotubeo Pump Vaults to provide pressure and flow
requirements, and to prevent debris from fouling valve
operation. An intet balt valve and a section of clear pipe
and union for each ouflet are provided for a complete
assembly that is easy to maintain and monitor. ldeal
valve location is at the high point ¡n the system. Refer t0

fntuoduction
orenco's automatic distributing valve assemblies, pressurized with small high-head effIuentpìrmps' are useful for distributing effIuent to multiple zones. These zones ,ä ¡" segmentsof sand filter manifolds, drainfieidr, o, other efiluJnt distribution systems. Distributingvalve assemblies cansubstantially simplify the design and installation of a distribution sys-tem and reduce installation costs. This is particulad! true where a distributing rrat o" assem-bly is used instead of multiple pumps u"øor electrióaüy oferated valves. Ad-ditionalty, ared¡ction in long term operatioo *à maintenance costs is realized due to a reduced sizeand/or number of pumps. More even distribution can be achieved on sloping sites by zoninglaterals at equal elevations. This eliminates drainback to lower lines and-theLequal distrib-ution of effluent that occurs at the beginning of a cycle.
Valve Operation
The valve itself has o:rly a few moving pârts, requires no electrici ty, andalternates automati-cally each cycle' Refer to Figure r foi the following valve operation description. The flowof the incoming eftluent forces the rubber flap disk-o to seat against the valve bottom @.þ opening @ in the rubber flap disk aligns with * op*iog in the valve bottom to allowflow to only one valve outlet. The stem dhour". u stai"rers steel spring which pushes therubber flap disk away from the valve bottom after the flow of effluent rör. ñ. stem actsas a cam follower and rotates the rubber flap disk as the stem is raised *å lo*".d throughthe cam 6' The force from the flow of efiIuent pushes the stem down through the cam andthe stainless steel spring pushes the stem back up tnro.rgtth" cam when the flow of effluentstops' Each linear motion of the stem allows the rubbeiflap disk to rotate half the distancenecessary to reach the next outlet. When there is no flow, ihe rubber ftap disk is in the ..up,,
position and is not seated against the valve bottom.

The Distributing Valve AssemblY
The orenco Automatic Distributing valve Assembly combines the distributing valve itself and sever-
al other cornponents to give a complete preassembled unit that is easy to install' monitor' and main-
tain. Figure 2 shows a complete urrr*bty. Because !]st-riuutins valves with several outlets can be
dillcult to rine ,rp unJ glueiogether in tne ficld, the discharge lines in the assemblies are glued in
place at Orenco. The rÃions 1i¡ attow removal and maintenance of the valve' The clear PVC pipe
sections (2) give a visuar check'of which discharge line is being pressurized. The inlet ball valve (3)
allows a quick, simple method to test for frope,. ialve cycling.-fn" ball valve also stops the flow of
effruent in case the pump is activated *r'"p""t"¿ry auring mãintenance or inspection. check valves
may be necessary o* tfr. discharge lines. úse of check rrãl,ott is discussed in the valve positioning
section.
Valve AssemblY llYdraulics
Liquid flowing through the valve assembly must pass ftt:"gh fairly small openings and make several
changes in direction.-B."u,rr. of this, t
"u.lto*re*
through the valve assembly are fairþ high' Table 1
gives the headross equations for several different ur*rrrrbli"r and Figure 3 shows the graphical repre-
sentations of these equations. orenco recommends that high-head turbine pumps be used to pressuf-
ize the valve assembries to en$re enough head is availabrı for proper system operation. High-head
turbine pumps are also reconrmended because the use of a distributing valve usually requires more
frequent pump cychng. The high-h"ad tr.bite pumps are designed for high cycling systems and will
outrast conventional effluent pumps by a factor of 10 or more in a high cycling mode. Furthermore,
the high-head turbinc pump intake is 12 inches of more above the bottom of the pump antl tends to
prevent any settred ,oiid, from being pumped into the distribution valve and obstructing its opera-
tion. A minimum flow rate through tne aistrituting valve is required to enlure- proper seating of the
rubber flap disk. Minimum tlowiates for the various models are givcn in Table 1'

The Pumping System
Although the distributing valve was designed for the irrigation industry, it has started to gain fairlywide acceptance in the effluent pumping industry. HowJver, because of the mechanical movementsof the valveo it is necessary to take steps to prevent solids from reaching the distributing valve thatmay impede the operation of the valve. orenco Biotube@ Pump vaults - when properly sized andinstalled - provide the necessary protection to prevent uatu. -utn ooi"".
'irr.
Biotube@ pump vault
1c.cer!s effluent only from the clear zone between a tank's scum and sludge layers and then filtersthis effluent through avery large surface area screen cartridge. Without tñis protection in effluentsystems, the valve has very little chance of reliable long-term operation.
valve Positioning l the discharge point is very important
The physical position of the valve in relation to the pump aff
for proper valve operation. Tho most reliable operation occurs w'en the valve is placed at the high
point in the system and as closs to tfr* poãp us possible' The transport line between the pump and
valve should be kept fuIl if possibte. rtne tine'is empty at the beginning of e_aclr cycle' pockets of
air during filling can cause iandom rot¿tion of the rrur*. The varve is particularþ vutnerable to this
erratic rotation with empty lines that ur. toog and not laid at a constant grade. An ideal valve loca-
If the final discharge point is more than about 2 feetabove the valve and the system does not drain
back into the dosing tank, check valves should be installed on the lines immediately following the
valve and a pressure ,eleáse hole or line should be installed just prior to the valve' This pressure
rerease hole or line can go into a return iine to the dosing tank oi to a "minid¡ainfreld' near the valve'
In order for the valve to rotate reliably, no mofe than abıut 2 feetof head should remain against the
valve to allow the rubber flap disk to return to its up position' In many cases' it may t¿ke from one
minute to several minutes for the pfessure in the rout* to be lowered enough for proper rot¿tion to
occur. Special care should be taken when insølling systems controlled by programmable timers to
ensure cycring does not occ*r too rapidly. Figure i iliustrates a varve assembry using check valves'

vation between the discharge rine out of the tank and the valve is iess than about 2 feet. If the valve
is located many feet below the dosing tanþ random cycring may occ'r while the transport line drains
through the varve at the end of the ,vrr".-Á pressure sustainingvalve rocated just before the distrib-

System Startup
Refer to the Hydrotek valve booklet that is provided with the distributing valve assembly for thesequencing of the valve outlets. The transport line should always be flushed with clean water beforeinstalling the valve' Any sand, gravel, o.-oth". foreign oq".tr that may have been in the pipe duringinstallation can easily become lıdged in the distributLg uäl*,", causing malfunction.
With the pump running, alternately close and open the ball valve on the distributing valve assemblyto check proper rotation of the valve. (Note: Ilcheck valves are used on the lines after the distribut-ing va-1v9,. the pump may need to be turned on and offto allow the pressure to be released from thevalve') If visual operation of which zone is operating is nofpossibie, watch the clear pipe on eachline for indication of which zone is operating.

Maintenance
Annually check for proper operation by following procedures listed in the Hydrotek Valve bookletand system startup procedures listed *bo.rr.
Tþoubleshooting
1. PROBLEM: valve does not change or cycre to next zone or outret
cAusE: The stem and disk assembly is not rotating when water flow is turned offand thenback on.
S0LUTION 1: Ensure that there is no debris inside the cam. clean and carefully reinstall the cam.SOLUTION 2: If fewer than the maximum number of outlets are being used, check the installationof the cam' Ensure that the stem and disk assembly is not being held down by animproperly inst¿lled cam. Refer to the cam replacãment instruJtions.

If the valve cannot u.ïru."¿ close to the high point of the system, a check valve
should be installed near the valve in the outletiine that runs uphill from the valve
and a drain line installed just prior to the valve to relieve the pressure'
2. PROBLEM: Water comes out of all the valve outlets
GAUSE: stem and disk assembly not seating properly on valve outlet'
sOLUTION 1: Check for sufficient water f10w. A minimum flow rate is required to properly seat
the disk as shown in Table 1'
solurloN 2: Remove the valve top and checkthe inside walls to ensure that nothing is interfering
with the up and down movement of the stem and disk assembly inside the valve'
SOLUTION 3: Make sure that the operating outlets are not capped and that the flow to the operat-
ing zones are not restricted in any marmer'
