r <br /> nco Technical Data . ■ <br /> Distributing <br /> Valves <br /> Applications General <br /> Automatic Distributing Valve Assemblies are used to pressurize multiple zone Orenco's Automatic Distributing Valve Assemblies are mechanically operated <br /> distribution systems including textile filters,sand filters and drainfields, and sequentially redirect the pump's flow to multiple zones or cells in a dis- <br /> tribution field.Valve actuation is accomplished by a combination of pressure <br /> and flow.They allow the use of smaller horsepower pumps on large sand <br /> filters and drainfields.For example,a large community drainfield requiring <br /> 300 gpm(18.90Usec)can use a six-line valve assembly to reduce the <br /> Top dew pump flow rate requirement to only 50 gpm(3.14Usec). <br /> Coupling Orenco only warrants Automatic Distributing Valves when used in conjunc- <br /> bon with High-Head Effluent Pumps with Biotube®pump vaults to provide <br /> pressure and flow requirements,and to prevent debris from fouling valve <br /> operation.An inlet ball valve,a section of clear pipe,and a union for each <br /> outlet are provided for a complete assembly that is easy to maintain and <br /> Distributing valve monitor.Ideal valve location is at the high point in the system.Refer to <br /> Union Automatic Distributing Valve Assemblies(NTP-VA-1)for more information. <br /> Clear pipe <br /> Standard Models <br /> V4402A,V4403A,V4404A,V4605A,V4606A,V6402A,V6403A,V6404A, <br /> V6605A,V6606A. <br /> Ball valve :, Product Code Diagram <br /> Elbow V F1n 7 A <br /> Side dew <br /> JTTAssernNy <br /> scharge connections installed: <br /> 02 = 2connections <br /> 03 = 3 amnecGons <br /> 04 = 4 connections <br /> 05= 5connections <br /> Elbows 06= 6 connections <br /> Avabhe discharge connections: <br /> 4 = 4 available amnectims <br /> 6 = 6 available camactions <br /> Irdet/outiet size,in.(mm): <br /> 4 = 1.25(32) <br /> 6 = 1.50(40) <br /> Bottom View Distributing valve <br /> Materials of Construction <br /> All Fittings Sch,40 PVC per ASTM specification <br /> Unions Sch.80 PVC per ASTM specification <br /> Ball Valve Sch,40 PVC per ASTM specification <br /> Clear Pipe Sch.40 PVC per ASTM specification <br /> Orenco Systems"Inc.,814 Airway Ave.,SuUietlin,OR 97479 USA•800-348-9843.541-459-4449•www.orerico.com NTD-SF-VA-1 <br /> Rex 2.0,0 03!17 <br /> Page 1 of 2 <br />
