Before you start, it is important that your flow requirements be defined in terms of Cv or flow coefficient. Cv is the valve flow coefficient expressing the rate of flow in gallons per minute of 0 F water with a pressure drop of 1 PSI across the valve. By correctly using the formula for liquids or gases, you will obtain an accurate Cv, necessary for your valve selection. Cv should be calculated for expected variations in pressure and required flow range. The Cv range for HOKE metering valves is approximately to 1. This is illustrated in the Cv vs handle turns flow curves shown with each valve series. Note that the more handle turns required to achieve a specified change in flow, the greater the valve s accuracy. The Cv range providing best control should fall within the straight portion of the curve with the nominal value centered. Using the straight portion of the curve gives approximately the same incremental flow for each turn of the valve handle. Once Cv requirements are determined, the following steps must be evaluated before making your final valve selection. 1. Define Pressure/Temperature Requirements HOKE metering valves are available from moderate vacuum to 5000 psig. Operating temperatures range from -5 to 50 F. There are no restrictions on pressure drop or downstream pressure for HOKE valves, however, best performance will be obtained if the downstream pressure is more than 50% of the inlet pressure.. Know Your Material Requirements Corrosion resistance should be your prime consideration when selecting materials, particularly the wetted or pressure boundary parts. There are times when the environment must also be considered in addition to the fluid media. The pressure/temperature demands of materials are normally covered by the material manufacturer s product specifications. HOKE products are designed using materials of similar corrosion properties whenever possible. If material selection is critical, please contact your nearby HOKE distributor. He can recommend options to help solve your problem. 3. Options Dial Indicator and micrometer handles are available for reproducing stem positioning. The HOKE Milli-Mite 1300 series is provided with a micrometer handle as standard equipment. Other handle options are available or can be made to order.. Final Performance Engineering design and manufacturing standards are critical elements of the metering valve you select and will affect its actual performance. Total control of these quality elements at HOKE assures you of valves with excellent stem positioning repeatability, low hysteresis, and extended metering range. HOKE Metering Valves 11
