Page 2 BULLETIN 10-10-8 The Sporlan Type R Valve family features balanced port design, an external adjustment assembly and the replaceable element assembly. The Type R with extended copper connec-tions has recently been expanded to include three conventional body styles, the R, ER, and SR plus new fractional capacity ER with extended copper connections provides excep-tional control in both flow directions making the ER an excellent choice for bi-flow heat pump applications.

5 The ER also features the 60 x 50 mesh stainless steel wire cloth inlet strainer as a standard feature; the 100 mesh inlet strainer is an optional feature available for 5/8 ODF and larger fitting Type ER is available in two body sizes. The small body provides capacities up to 8 tons R-22 and R-410A, up to 5 tons R-134a, and up to 6 tons R-404A. Large body ER Valves extend capacities to 12 tons R-22 and 15 tons Sporlan Type R, with SAE flare connections, and the Type SR with the removable strainer assembly share the same balanced port construction as the ER. The R is complete with the 100 mesh inlet strainer as an integral part of the fitting while the SR has a 100 mesh removable strainer that can be cleaned or replaced while the valve remains soldered to the system tubing.

6 These Valves are ideally suited for small to large capacity refrigeration applications that could oper-ate over widely varying operating conditions for refrigerants including R-22, R-134a, R-404A, and R Valves may be applied in bi-directional Connections3/8 SAE, 1/2 SAE, 3/8 ODF, 1/2 ODF, 5/8 ODF, 7/8 ODF, 1-1/8 ODFM ating Distributors (See BULLETIN 20-10)D260, D262, 1620, 1622, 1112, 1113, 1115, 1116, 1603, 1605, 1606, 1608, 1650(R), 1651(R), 1653(R), 1655(R)Flare ConnectionsExtended Solder ConnectionsExtended Solder Connections with Forged Inlet and Replaceable StrainerTYPE ERODF(Internally Equalized)TYPE EREODF(Externally Equalized)TYPE RSAE(Internally Equalized)TYPE RESAE(Externally Equalized)TYPE SREODF(Externally Equalized)TYPE SRODF(Internally Equalized) TYPE R, ER, SRVALVETYPEBODYSEATPINPINCARRIERPUSHROD( S)

8 SELECTION PROCEDUREThe following procedure should be used when selecting a Sporlan TEV:1. Determine the liquid temperature of the refrigerant entering the valve. The TEV capacity tables on pages 5-8 are based on a liquid temperature of 100 F (38 C) for R-22, R-134a, R-401A, R-404A, R-407C, R-408A, R-409A, R-410A, and R-422D. For other liquid temperatures, apply the correction factor given in the tables for each refrigerant. For example see Table Determine pressure drop across valve. The pressure drop correction factors are based on standard liquid temperature and pressure drop.

9 The standard pres-sure drop is dependent on the evaporator temperature. To determine the pressure drop, subtract the saturated pressure equivalent to evaporator temperature from the condensing pressure. The condensing pressure used in this calculation should be the minimum operating condensing pressure of the system. From this value, subtract all other pressure losses to obtain the net pressure drop across the valve. Use this value to determine the pressure drop correction factor. For example see Table C. Be sure to consider all of the fol-lowing possible sources of pressure drop: 1.

10 Friction losses through refrigeration lines including the evaporator and condenser. 2. Pressure drop across liquid line accessories such as a solenoid valve and filter-drier. 3. Static pressure loss (gain) due to the vertical lift (drop) of the liquid line. 4. Pressure drop across a refrigerant distributor if used. Refer to BULLETIN 20-10 for information on refrigerant Select valve from the capacity tables. Select a valve based on the design evaporating temperature. If possible, the valve capacity should be equal or slightly exceed the design rating of the system. Be sure to apply the appropriate correction factors for liquid temperature and pressure drop.
