The "D" check feature on a vertically installed 6" and larger valves must be horizontally installed.
Typical Applications
Typical applications include pressure reducing valve station
using Model 90-01BYKO and Model 90-01ASKO in parallel to
handle wide range of flow rates. Larger Model 90-01BYKO valve
meets requirements of peak loads and smaller Model
90-01ASKO handles low flows.

The Cla-Val Model 90-01KO Anti-Cavitation Hytrol Pressure Reducing
Valve automatically reduces a higher inlet pressure to a steady lower down-
stream pressure, regardless of changing flow rate and/or varying inlet pres-
sure. This valve is an accurate, pilot-operated regulator capable of holding
downstream pressure to a pre-determined limit. When downstream pres-
sure exceeds the pressure setting of the control pilot, the main valve and
pilot valve close drip-tight.
If a check feature is added, and a pressure reversal occurs, the down-
stream pressure is admitted in the main valve cover chamber, closing the
valve to prevent return flow.
Cla-Val Model 90-01KO Pressure Reducing Valve with Anti-Cavi-
tation Trim provides for optimum downstream pressure control
while reducing noise and eliminating damage associated with cav-
itation.
See Cavitation Guide to determine if the valve is a candidate for
the KO Anti-Cavitation Trim.
