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 />pump flow rate requirement to only 50 gpm (3.14Usec). <br />Orenco only warrants Automatic Distributing Valves when used in conjunc- <br />tion 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 />monitor, Ideal valve location is at the high point in the system.
