Technical Data Stop Check Valves Selecting the Proper Size Determining Pressure Drop Since stop-check valves have a floating disc member, it is important that the valve be sized to provide full disc lift under flow conditions prevailing during the major portion of the service life. If the valve is too large, the disc will float in a partially open position and may cause fluttering of the disc and rapid wear. Conversely, if the valve is too small, pressure drop will be excessive. The chart on the following page is a graphic presentation of flow data determined by test. Its use offers a simple method of determining the best size stop-check valve, as well as the pressure drop under varying conditions of flow, without any computation. How to Use the Chart Shown on the Following Page Given: Steam Pressure-Temperature...0 psig 0 F Flow Rate...Typical Daily Demand Curve Find: RATE OF FLOW IN POUNDS PER HOUR 00,000 90,000 0,000 70,000 0,000 0,000 0,000 0,000 0,000 0,000 0 Midnight Typical Daily Load-Demand Curve 0-Inch Valve -Inch Valve AM Noon TIME OF DAY PM Midnight Valve Catalog No. and the best size for above installation. Solution:. Enter the Temperature chart at 0 F. Move vertically upward to the curved line for 0 psi, then horizontally to the right to establish a point on the specific volume scale. From this point, draw a line through the flow rate being investigated (00,000 Lb/H) and establish a point on Index.. From that point, draw another line through the valve size, for example the -inch size, and establish a point on Index. Now move horizontally to the diagonal pressure drop line on the right side. Where these lines intersect, the pressure drop is 7. psi for the -inch, Class 0 globe valve and. psi for the -inch Class 0 angle valve. Chart solutions resulting in a point on Index that falls below the Line A-A for Class 0 valves indicate the disc will not be fully lifted under the flow conditions used. Operation under such conditions is not recommended but, at times, must be tolerated for short periods during the low loads.. Enter the chart where Line A-A intersects Index for Class 0 valves. Move diagonally upward through the size being investigated (-inch) and establish a second point on Index. From this point, extend a line to the specific volume established in Step and at its intersection with the flow rate line, read,000 Lb/H as the minimum flow rate at which the disc will be in the fully lifted position. The pressure drop at this flow rate is.9 psi for globe and. psi for angle valves.. Repeat Steps and for other possible valve sizes, tabulate results, and make size selection on basis of pressure drop and duration of partial disc lift considerations. Valve Press drop @ Max.Min. Flow Rate for Size Flow rate (00,000 #/Hr.), psi Wide open valve (Inches) Globe Angle #/Hr. 0..,00 7..,000 0..,000 Dotted lines on Demand Curve indicate minimum flow rates for wide open " and 0" valves.. The best choice for this example would be the 0" size because pressure drop is much lower and duration of partially lifted disc is only slightly greater than for the " size.. Pressure drop for any intermediate flow condition can be determined as outlined in Steps and. 7. Valves require a minimum of 0 psi differential pressure to seat the valve.

Stop Check Sizing Information STOCKHAM STOP-CHECK VALVE SIZING INFORMATION REQUIRED Figure 0 - Straight Through Y-Pattern Figure - Angle Y-Pattern Minimum constant pressure of 00 psig required for valve to operate properly. Systems below 00 psig will not be possible to size Information required to properly size Stop-Check valves includes both minimum and maximum operating conditions. Maximum Operating Conditions Customer: Pressure: psig Maximum Project: Temperature: F Date: Specific Volume: cu. Ft/lbs (#a) Customer: Flow Rate: lbs/hr. Maximum Phone #: e-mail: (#a) We can obtain specific volume from steam table when provided with the temperature and pressure. Minimum Operating Conditions Pressure: psig Minimum Temperature: F Specific Volume: cu. Ft/lbs (#a) Flow Rate: lbs/hr. Minimum (#a) We can obtain specific volume from steam table when provided with the temperature and pressure. In addition, valve installation orientation should be considered as well as the overall system of operation. Please keep in mind that our stop-check valves are metal seated and are a safety valve to prevent backflow. Since they are metal seated there is some allowable leakage rate per API-9. A minimum of 0-0 psi pressure differential is required for this valve to properly operate. In order to properly run sizing calculations we require the flow rate (lbs/hr.) thru the individual units (both minimum and maximum flows) along with the temperatures and pressures, again both minimum and maximums. Operating Conditions: Are all the valves on one boiler, or are they on separate boilers? Are the boilers operated independently of each other, or are the units manifolded together to cycle between boilers? Are the idle boilers allowed to fully depressurize, or are they maintaining a temperature/pressure in the standby boilers? If so, what pressure/temperature is being maintained on standby and what is the operating system pressure? As indicated in our literature, Stockham Figure F-0 can be operated in both a horizontal, and a vertical (upflow) line. The check valve feature should not be relied upon for primary shutoff. The calculations are based upon temperatures, pressures, and flow rates provided. If there are significant fluctuations in any of these operating condition parameters than the units may not operate properly. The reason we require information about stand-by mode on the boilers is because we have found that a significant number of end users have in the past several years changed their method of operation of multiple boilers. In the past the units would have been cycled between boilers and the non-active boiler allowed to totally de-pressurize and temperature normalize. More recently, we have seen a cycling program that keeps the stand-by unit with some temperature and with a significant pressure. When this method is used the stop-checks have a pressure on both sides of the piston/disc seal, causing the valves to not properly check. Stop-Check Document 00
