Straight-ihru-Raw Design RV series All models except RV131 are CSA design certified for 112 psi rated pressure under the ANSi standard for gas Pressure regulators; and CSA listed to certify compliance with nationally published safety, construction, and performance standards. They are main burner only, non -lockup type. They should not be used as a line gas pressure regulator ahead of low pressure controls. Use only where downstream controls can operate at line pressure_ Refer to other Maxitrol sales bulletins for proper types. The RV52, RV53, & RVg1 are suitable for rnultipoise mounting. TheRV81, RV91, RV111, & RV131 are - recommended for normal horizontal position only. Maxitrol's original Straig ht-Thru-Plow design meets your needs for high capacities at loud inlet pressures. The basic difference between S-T-F design and other type regulators lies in the conical valve. The cane principal permits gas to low straight through th a regulator without changing directions. Frictional flow resistance is reduced, resulting in greater capacity. The improved flowpattern provides accurate sensitive regulation at extremely low Pressure differentials. The ability of the regulator to handle large capacity appliances with limited supply pressure offers a definite advantage to designers of commercial and industrial gas --fired equipme n t. Models up to the three inch pipe size have high strength pressure cast aluminum housings. The RV131 four inch model is Of cast iron and steel construction.

Check capacity Chart above for 4" regulator, the required maxim urn flow rate, RVI31. 2. Note that at a flow rate of 21,172 CFH the Example No. 1-To select a regulator of ample capacity to pressure drop is 2" w.c. handleflow. 3. Multiply this by two to obtain recommended differential pressure (4"vv.c.). KNOWN: 4. Subtract 4" differential pressure from 10"w.c. Pipe size 2--112", flow rate 8,000 CFH (0,64 sp gr), inlet inlet pressure to obtain maximum recommended pressure 9" w.c., desired outlet pressure 5" w.c. outlet pressure setting of 6" w.c- SOLUTION: 1. Determine differential pressure available, lnletpressure 9" uv.c. Subtract outlet pressure - 5" w.c. Available differential pressure 4" w.c, 2. When determining capacity Maxitroi recommends that the pressure drop not exceed 112 of available differential pressure (1/2 of 4" w c = 2" w-c.). 3. Check Capacity Chart to determine which regulator has a pressure drop of 2" w.c. or less at a flow rate of 8,000 CFH. 4. The RVI I I meets these standards with a flow rate of 12,134 CFH for the 2-112" pipe size at 2" w.c. pressure drop. The 2-112" RV91 flows 5422 CFH at 2" w.c. pressure drop. Therefore, the RV111--2-1/2" is the correct regulator to use. Example No. 2---To determine maxim um recommended operating outlet pressure.
