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.
