PRESSURE REDUCING VALVES 81 IS PR37.01 E 04.05 DESCRIPTION The ADCA PRV37 pilot operated pressure reducing valves are designed for use on steam, compressed air and other gases. They are suitable for pressure reducing stations throughout all industries. Connections are flanged DIN. Different connections are available on request. MAIN FEATURES Robust steel construction. Suitable for dead end conditions. OPTIONS: USE: AVAILABLE MODELS: SIZES: CONNECTIONS: INSTALLATION: CAPACITIES : Soft faced valve for air and gases. Special pressure top for low pressures. Regulating screw with top cap. Saturated steam,compressed air, and other gases (Group 2) compatible with the construction. PRV37/S - steel PRV37/SS - complete stainless steel construction. DN 15 to DN 50 . Flanged DIN. Special flanges upon request. Horizontal installation. A “Y” strainer, steam separator and steam trap should be provided upstream of the valve. Please consult or ask for selection table. LIMITING CONDITIONS Body design conditions : PN 25 PN 40 Maximum upstream pressure (steam) : 21 bar 25 bar Maximum upstream pressure (air) : 25 bar 31 bar Maximum downstream pressure : 17 bar 17 bar Minimum downstream pressure : 0,35 bar* 0,35 bar* Minimum operating temperature : -10 ºC -10 ºC Maximum operating temperature : 260 ºC 260 ºC Maximum cold hydraulic test : 40 bar 60 bar * 0,07 bar with low pressure top (limited at 7bar inlet). PRESSURE RANGES Spring colour Green Blue Red Black Red. pressure (bar) 0,35 – 2 1,5 – 5,5 3,5 – 8,5 7 – 17 It is preferable to select a spring range where the desired reduced pressure is at the upper end of range . USEFUL NOTES ON VALVE AND PIPE SIZING A special low pressure top assembly should be fitted for outlet pressures from 0,07 up to 0,35 bar. Two diaphragms must be fitted when reduced pressure is 10 bar and above. Two regulators in parallel should be used on larger sys- tems where minimum flow is less than 10% of maximum. If the flow is unknown it is possible to estimate it based on pipe size or equipment heat requirement-please consult. The balance pipe connection should enter downstream pipe at a minimum of 1 metre from valve.A spool piece can be supplied to house the balancing pipe.

Spring Nr. 63 63 63 63Correction factors: Correction factors must also be used for certain pressure ratios as follows:
Remarks: The pressures have to be inserted in barg . No correction factor should be used for smaller pressure ratios than 0,7Example (valve selection): Saturated steam capacity 300 Kg/h ; Upstream pressure:3 bar ; Downstream pressure required : 2 bar
Solution :First determine correction factor for pressure ratio 1,25f0,751312
=®=++
Go to 3 bar in the column “bar” of the capacity table. By following the horizontal line you can find out the values for selectionof pressure reducing valve.Looking for an equal or higher value than 300 Kg/h. In this case it will be 400Kg/h.Now, go to the top of the table and read off the nominal size : DN 32.On the actuator and spring selection table, for downstream pressure of 2 bar we may see that the recomendedactuator is type A-2 , considering the valve supplied with spring Nr.60.How to order : RP45 DN 32 PN 16 valve complete with spring Nr.60 ,type A-2 actuator,condensate vessel and copper tube impulse line.Remarks: For superheated steam please consult. For determination of upstream and downstream pipe sizes please consult.
, mutiply the given capacity 300 x 1,25 = 375 kgs/h
