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. An improved flow pattern provides accurate, sensitive regulation at extremely low pressure differentials. Typical applications include residential, commercial, and industrial gas-fired appliances and equipment used on low or medium pressure gas supplies.

210 SERIES

Balanced Valve Design

The 210 series is a lockup type regulator. The balanced valve design makes it possible to maintain steady outlet pressure control with widely varying inlet pressures. The regulator has an integrated dampening mechanism in the breather outlet and the sensing tube to improve regulating stability and reduce hunting tendencies. The 210 series provides precise regulation over a wide range of pressures and flow rates. Applications include gas-fired boilers, steam generators, industrial furnaces, and ovens.

RZ and 210Z Zero Governor Design

Both the RZ and 210Z series are adaptable for air-gas mixing applications. Because of the balanced valve construction, Z-models offer superior performance at an economical price compared with other types of atmospheric regulators. Maxitrol’s RZ and 210Z Zero Governor model regulators are used for flow control of burners, nozzel mixers, mixing tees and proportional premixers.

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. When the regulated outlet pressure of the servo regulator is changed by spring adjustment, the outlet pressure of the 220 main regulator will be changed proportionately. Applications include industrial furnaces and ovens.

SIZING A REGULATOR See www.maxitrol.com for our Regulator Sizing Program. Please Maxitrol directly for more information on sizing a regulator.

System Requirements When sizing a regulator the following must be known:

• • • • • • •

Gas Type Available Inlet Pressure Desired Outlet Pressure Zero Governor Application (indicated by model number ending in “Z”) Will the regulator control main burner and pilot load OR main burner only? Required minimum and maximum flow rate in cfh or m3/h or Btu/h Pipe Size

In most cases, the manifold pipe size has already been selected on the basis of good engineering practice, and the regulator pipe size should conform to this size. The capacity of any regulator is not an absolute value but will vary with the application depending on the prevailing differential pressure.

Service and installation must be performed by a trained/experienced service technician. All products used with combustible gas must be installed and used strictly in accordance with the instructions of the Original Equipment Manufacturer (OEM) and with all applicable government codes and regulations, e.g. plumbing, mechanical, and electrical codes and practices. These instructions do NOT supersede OEM’s installation or operating instructions. All Maxitrol products should be installed and operated in accordance with Maxitrol Safety Warning Instructions.

HOW TO CALCULATE PRESSURE DROP AT VARIOUS FLOW RATES FROM CAPACITY CHART LP Applications - When using natural gas pressure drop chart to determine LP pressure drop in of Btu/h, multiply NAT Btu/h by 1.61; in of CFH multiply NAT CFH by 0.645.

Formula: P2 = P1 x (Q2/Q1) 2

P2 = Pressure drop at desired flow rate P1 = Known pressure drop

Q2 = Desired flow rate Q1 = Known flow rate

A. Check Capacity Chart, insuring regulator has ample range B. Know the minimum encountered inlet pressure. of regulation and individual load capacities (for use with pilot) MINIMUM INLET PRESSURE MINUS “P2” MUST for the application. BE GREATER THAN DESIRED OUTLET PRESSURE. Solve for “P2” using the formula above. (See examples on page 59.)

58


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. The RV48 (without “L” fixed orifice) is the correct regulator to use for the application.

STRAIGHT-THRU-FLOW (S-T-F) For main burner only applications not requiring a lockup type regulator. When sizing the S-T-F Series, it is recommended that pressure drop not exceed 1/2 of available differential pressure. Example: To select an RV type regulator: • Known: Flow rate 2,000,000 Btu/h; pipe size 1 1/4”; inlet pressure 9” w.c.; outlet pressure 5” w.c. • Solution: The RV81(1 1/4”) has a maximum capacity of 2,500,000 Btu/h. The pressure drop at a flow of 2,000,000 Btu/h is 0.66” w.c. The RV81 (1 1/4”) is the correct regulator to use with this application. The pressure drop of the RV61 (1 1/4”) at a flow rate of 2,000,000 Btu/h is 2.64” w.c. This is within the available differential but exceeds the recommended 50% maximum.

LEVER ACTING For main burner and pilot load application requiring positive dead-end lockup (see Definitions page 63). Example: To select a 325 Series regulator: • Known: Single 145,000 Btu/h burner; pipe size 1/2”; inlet pressure 2 psi; outlet pressure 7” w.c. • Solution: The 325-3’s pressure drop at a flow rate of 145,000 Btu/h is 7” w.c., well below the available differential of 1 3/4 psi. The 325-3 (1/2”) is the correct regulator to use with this application.

BALANCED VALVE For main burner and pilot load application requiring a lockup type regulator or zero governor usage (see Definitions page 63). Example: To select a 210 or R/RS Series regulator: • Known: Desired flow rate 6,000,000 Btu/h; pipe size 1 1/2”; inlet pressure 1 psi; outlet pressure 9” w.c. • Solution: The 210E (1 1/2”) has a maximum capacity of 10,000,000 Btu/h. The 210D (1 1/2”) has a capacity of 6,000,000 Btu/h. Therefore, the 210E (1 1/2”) will give you the desired outlet pressure of 9” w.c. and is the correct regulator to use for the application.

NOTICE

Maxitrol vent limiting devices eliminate the need to run vent piping to the outside. Vent limiting devices are designed for use indoors and in spaces where limiting the amount of gas escapement due to diaphragm failure is critical. Vent limiting devices should not be used outdoors if they are exposed to the environment. Vent protectors are available for all outdoor applications to ensure proper vent protection.

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.

Differential Pressure The difference between inlet pressure to the pressure regulator and outlet pressure from the pressure regulator. To obtain differential pressure, subtract the desired outlet pressure from available inlet pressure.

Line Pressure Regulator A pressure regulator intended for installation in a building gas distribution system between the building service regulator or LP-gas 2 psi service regulator and gas utilization equipment.

Lockup Type Under no flow conditions, outlet pressure will rise above adjusted pressure but will not rise to line pressure.

Minimum Capacity (Main Burner Only) Minimum capacity of a pressure regulator designed to control the flow to the main burner only.

Maximum Capacity (Main Burner Only) Maximum capacity of a pressure regulator at which the pressure regulator will control main burner pressure within acceptable limits.

Overpressure Protection Device (OPD) A device which under abnormal conditions will act to reduce, restrict, or shut off the supply of gas flowing into a system to prevent pressure in that system from exceeding 2 psi. • Monitoring Regulator: An overpressure protection device which functions as a second pressure regulator in series with the primary pressure regulator. • Overpressure Relief Device: An overpressure protection device which functions by discharging gas from the downstream system to a safe location. • Overpressure Shut-Off Device: An overpressure protection device which functions by completely shutting off the flow of gas into the downstream system.

Pressure Drop The natural loss of pressure that occurs in the pressure regulator (or in any valve or pipe) due to friction. This friction impedes fluid motion, without regard to artificial losses deliberately created by diaphragm action. The equivalent flow rate for a loss in given pressure with the pressure regulator valve in a normally wide open position.

Rated Inlet Pressure The highest inlet pressure for which the control is intended to be used.

Vent Limiter

Maximum capacity of a pressure regulator at which the pressure regulator will control main burner and pilot line pressure within acceptable limits.

A means that limits the flow of gas from the atmospheric chamber to the atmosphere in the event of a diaphragm rupture. This may be either a limiting orifice or a ball check vent limiting device. • Limiting Orifice Type: A vent limiter where the flow through the limiter is the same in both directions

Capacity

Zero Governors

Maximum Capacity (Main Burner and Pilot)

Total load Btu/h of all appliances combined.

Maximum Individual Load

They require an external impulse signal, such as top loading with pressure or generating vacuum in the downstream piping.

Largest single appliance or burner served by the pressure regulator.

Maximum Individual Load Capacity 1. The maximum capacity or flow at which a line pressure regulator will control lockup pressure within acceptable limits. 2. The maximum capacity or flow at which a pressure regulator will control pilot line pressure within acceptable limits. © 2017, Maxitrol Company. All Rights Reserved.
