DRAFT 09.18.2013 RV SERIES Straight-Thru-Flow Design Maxitrol’s original straight-thru-flow (STF) design regulators are non-lockup type regulators for high capacities at low inlet pressures. The difference between STF design and other type regulators is the conical valve. The cone principal permits gas to flow straight through the regulator without changing directions. Frictional flow resistance is reduced, resulting in greater capacity.

DRAFT 09.18.2013 220 SERIES Pilot Loaded Design The 220 series uses a servo-operated design rather than a spring-loaded design and can deliver higher outlet pressures than conventional spring-loaded models. The main diaphragm of the model 220 is loaded with gas pressure instead of spring pressure. A small pilot regulator, located in the upper housing, accurately controls this gas pressure.

DRAFT 09.18.2013 SIZING A REGULATOR Sizing Examples RUBBER SEAT POPPETS For main burner and pilot load applications. Example: To select an RV type regulator: • Known: Single 150,000 Btu/h main burner; pipe size 1/2”; inlet pressure 7” w.c.; outlet pressure 4” w.c. • Solution: The RV48 (1/2”) has a maximum capacity of 230,000 Bth/h and a maximum individual load of 160,000 Btu/h. The pressure drop at a flow rate of 150,000 Btu/h is 0.4” w.c., well below the available differential of 3” w.c.

DRAFT 09.18.2013 DEFINITIONS Dead End Lockup Non-Lockup Type Pressure will be maintained within ANSI/CSA limits under no flow conditions. The amount of climb above set point is influenced by inlet pressure, flow rate before no flow condition and piping arrangement. Dead end lockup pressure regulators must be properly sized for desired performance. Under static conditions when no gas is flowing, outlet pressure will rise to line pressure.
