16 Orifice Capacities Sizing Examples The 300 Series Electromatic all Valve is supplied with standard orifice bores. Capacity tables on pages 300EV.17 through.22 specify the relieving capabilities of these valves with a maximum or standard orifice size. Orifice sizes smaller than standard may be specified to reduce the capacity to less than that stated in the capacity tables. resser, Inc. recommends that the 300 EV be sized as an integral part of the total safety valve system in order to ensure that the safety valves operate properly and within ASME requirements for set pressure, lift and blowdown. Total system sizing is not included in the following examples. or total system sizing, refer to Safety Valve Product Information Sheet SV/PI-3, or submit the total information required in the Ordering Information section to the factory for review. Example 1 or a new installation with no piping connections specified: Set Pressure: Required Capacity: 2000 psig 90,000 pph 1000 and 3% overpressure Non-ASME Section I rated Step 1 etermine the saturated capacity and full bore size from the appropriate capacity tables on pages 300EV.17 through.22. The selected capacity should be greater than or equal to the required capacity. If not, select the next larger bore size. Page 300EV.18 Capacity Tables 1.70 ore,, 3_7 Capacity at 2000 psig = 28,34 pph saturated 28,34 pph 90,000 pph Select #7 orifice designation Step 2 Correct for superheated steam temperatures using the Superheat Correction actors on page 300EV.2. Convert the set pressure from psig to psia flowing pressure then determine the superheat correction factor at the relieving temperature (interpolate when necessary). Multiply the saturated steam capacity calculated in Step 1 by the selected correction factor. The calculated capacity should be greater than or equal to the required capacity. If not, repeat Step 1 and select a larger bore size. Step 3 etermine any required reduction in capacity or bore size. Calculate the percentage of required capacity versus the full capacity as calculated in Steps 1 and 2. Using the section titled Reduced ore Selection and Capacity actor on page 300EV.23, refer to the table that corresponds to the full bore size selected. rom the column marked Relation to 100%, select the percentage that is equal to or greater than the calculated percentage. Multiply the full capacity corrected for temperature by the capacity factor selected. The reduced bore capacity should be greater than or equal to the required capacity.

25 Orifice Capacities Reaction orces Illustrated to the right is a CONSOIATE Electromatic all Valve. When the valve is closed, an upward force is exerted in the valve neck ( P ), due to valve internal pressure. Valve necks are designed to resist the force and circumferential stresses due to valve internal pressure. R When the valve opens, the force remains constant until some overpressure occurs. The force resulting from set pressure plus overpressure ( SP ) must be balanced by resisting forces in the valve neck. Once flow has been established, the steam escapes upward through the discharge connection; this results in force ( R ) acting downward at the center line of the discharge pipe. orce R is represented by the equation: = MV + PA A = area of outlet, sq. W lb/sec lb. sec M = = = g ft/sec 2 ft P = static pressure, lb/sq. V = velocity, ft/sec. In addition to actual valve capacities, reaction force valves are based on pressure, temperature, and valve configuration. orces for a particular valve type will apply regardless of inlet connection used; i.e. flange, screwed, or welded. or valve installations which vent to a closed system or solidly piped discharge lines, changes which occur in reaction forces, and the effects on nozzles, headers, and discharge lines should be considered. orce values indicated apply only when valves have been installed in accordance with ASME Code or resser Maintenance Manual recommendations.
