Pressure Reducing Valve - Flow and Control

1 Pressure Reducing ValveTypical ApplicationsTypical applications include Pressure Reducing Valve stationusing Model 90-01BY/690-01BY and Model 90-01AS/690-01 ASin parallel to handle wide range of flow rates. Larger Model 90-01BY/690-01BY Valve meets requirements of peak loads andsmaller Model 90-01AS/690-01AS handles low DiagramItem Description1 Hytrol (Main Valve )2X58 Restriction Fitting3 CRD Pressure Reducing ControlOptional FeaturesItem DescriptionAX46A Flow Clean StrainerBCK2 (Isolation Valve )CCV Flow Control (Closing)*DCheck valves with Isolation ValveSCV Flow Control (Opening)Y X43 "Y" Strainer*The closing speed Control (optional) on this Valve shouldalways be open at least three (3) turns off its PressureIsolation ValveGaugeConstantDownstreamPressureCLA- VAL 90-01BY/690-01 BYPressure Reducing ValveCLA-VAL 90-01AS/690-01 ASPressure Reducing Valve Sensitive and Accurate Pressure Control Easy Adjustment and Maintenance Tamper Resistant Optional Check Feature Fully Supported Frictionless DiaphragmThe Cla-Val Model 90-01/690-01 Pressure Reducing Valve automaticallyreduces a higher inlet Pressure to a steady lower downstream Pressure ,regardless of changing flow rate and/or varying inlet Pressure .

2 This valveis an accurate, pilot-operated regulator capable of holding downstreampressure to a pre-determined limit. When downstream Pressure exceedsthe Pressure setting of the Control pilot, the main Valve and pilot valveclose a check feature is added, and a Pressure reversal occurs, thedownstream Pressure is admitted in the main Valve cover chamber,closing the Valve to prevent return Model90-01 KOAnti-Cavitation Trimfor Excess Pressure DropConsult Cavitation ChartIsolation Valve Gauge Constant Downstream Pressure High Pressure Cla-Val Model 90-01KO/690-01 KOPressure Reducing Valvewith Anti-Cavitation Trim provides for optimum downstreampressure Control while Reducing noise and eliminating damageassociated with Cavitation Guide to determine if the Valve is a candidate forthe KO Anti-Cavitation (Full Internal Port)690-01(Reduced Internal Port)Note.

For 100-01 basic valves , suggested flow calculations were based on flow through Schedule 40 Pipe. Maximum continuous flow is approx. 20 ft/sec ( meters/sec) &maximum intermittent is approx. 25 ft/sec ( meters/sec) and minimum continuous flow is approx.

6 1 ft/sec (.3 meters/sec). For 100-20 basic valves , suggested flowcalculations were based on flow through the Valve seat. Approx. 26 ft/sec ( meters/sec) was used for maximum continuous flow & 1 ft/sec (.3 meters/sec) is used forminimum continuous flow. Maximum continuous flow through the Valve seat for the 30 100-20 is approx. 20 ft/sec ( meters/sec). Maximum continuous flow through thevalve seat for the 36 , 42", 48" 100-20 is approx. ft/sec.
