Model 119-15 (Fueling Service) Model 119-15 Filter Separator Rate of Flow/Shut-Off/Check Valve Global performance. Personal touch. TOLL FREE 1.888.628.8258 phone: (918)627.1942 fax: (918)622.8916 7400 East 42nd Place, Tulsa, OK 74145 email: [email protected] website: www.controlvalves.com The Model 119-15 has a very specific purpose: to limit the flow of fuel through a filter separator, close fully in the event of high water levels in the filter separator sump and close to prevent reverse flow. To perform this task, the Model 119-15 must operate in conjunction with one of the OCV 800 Series interface float pilots. SERIES FEATURES Controls or limits flow to a predetermined rate Built-in orifice plate for sensing flow rate Extra-sensitive differential pilot Flow rate is adjustable with single screw High capacity pilot system provides quick closing on water slug Check feature integral to pilot system Can be maintained without removal from the line Factory tested and can be preset to you requirements Valve position indicator Model 119-15 SCHEMATIC OPERATION With little or no water in the sump of the filter separator, the float of the interface pilot is down. The float pilot routes vessel pressure to the bonnet of the three-way auxiliary pilot. This positions the three port auxiliary pilot to connect the bonnet of the main valve downstream, allowing the valve to open. While open, the rate of flow pilot, located in the valve inlet flange, senses the differential across the integral orifice plate and responds to changes in this differential by modulating the main valve to prevent the flow rate from exceeding the predetermined maximum. With a high water level in the sump of the filter separator, the float of the interface pilot is up. The float pilot vents pressure from the bonnet of the three-way auxiliary pilot, shifting it to apply full inlet pressure to the bonnet of the main valve and drives the valve fully and tightly closed. Should outlet pressure exceed inlet pressure, the valve’s reverse flow check feature will close the valve. COMPONENTS The Model 119-15 consists of the following components, arranged as shown on the schematic diagram: 1.) Model 65 Basic Control Valve ( Fail Closed) 2.) Orifice Plate 3.) Model A224 Accelerator Pilot 4.) Model 2450 Rate of Flow Control Pilot 5.) Model 141-3 Flow Control Valve ( Opening Speed Control) 6 A.) Model 141-1 Check Valve 6 B.) Model 141-1 Check Valve 7.) Model 123 Inline Strainer 8.) Model 155L Visual Indicator REVISED 12/04/09 MAX.

SIZING Sizing of the Model 119-15 is typically the same size as the filter separator discharge connection.
