Size and Capacity Information For Watts Series 127 and 152A Pressure Regulators For steam service the correct size valve is most important for satisfactory regulator service, and selection should be carefully consid- ered. In a broad sense, the smallest size regulator that will satisfy the peak demands of a given installation is the correct size. If a reg- ulator is too large, wire drawing of the seat and disc will result — if too small, service will be inadequate and regulation will be uneven. Size of the valve is in direct relation to the demand and it is determined by the weight of steam required...

Series 127 Standard Reduced Pressure Range Chart The Table shows minimum and maximum reduced pressure ranges obtainable with various selections of chamber diameters and adjusting spring, depending on supply pressures. VALVE SIZE MODEL INITIAL PRESSURE Example: Initial pressure is 100 lbs., reduced pressure is 50 lbs. and capacity required is 1500 lbs. of steam per hour. By referring to the proper intial reduced pressure column (100 up to 50) 1560 lbs. per hour is closest to Required Capacity and corresponds to a Type 127 valve, size 1". Note: For reduced pressure above those shown for each initial...
