Orenco automatic distributing valve assemblies are mechanically operated and sequentially redirect the pump’s flow to multiple zones in a distribution field or treatment system. Valve actuation is accomplished by a combination of pressure and flow. Automatic distributing valve assemblies allow the use of smaller horsepower pumps on large sand filters and drainfields. For example, a large community drainfield requiring 300 gpm can use a six-line valve assembly to reduce the pump flow rate requirement to only 50 gpm.

The use of high-head effluent pumps with Biotube pump vaults are required to provide pressure and meet flow requirements, and to prevent debris from fouling valve operation.  An inlet ball valve, a section of clear pipe (for monitoring), and a union for each outlet are provided for a complete assembly. Ideal valve location is at high point in system. Refer to Orenco Automatic Distributing Valve Assemblies (NTP-VA-1) before installation. 

Orenco Automatic Distributing Valve Typical Application

  • Large drainfield dosing when smaller pumps are desired
  • Even distribution to zoned disposal areas
  • Sand filter dosing
  • Multiple Orenco AdvanTex treatment pod dosing
