The 4200 Series was designed to meet your requirements for a dependable, cost effective, high capacity boiler safety valve. This product is manufactured in our Brecksville, Ohio, ISO 1 certified facility. In addition, the 4200 Series safety valve is available at many of our FAST (Farris Authorized Service Team) Centers which are certified by the National Board of Boiler and Pressure Vessel Inspectors to assemble, set and test steam valves. Please visit our website, for a list of Farris representatives and FAST Centers in your region. Sizing Information...10 Dimensions & Weights...11 Conversion Factors...12 Warranty All products manufactured by Farris Engineering are warranted free of defects in material and workmanship when used within the range recommended for a period of one year after installation or eighteen months from delivery. When authorized, any defective product may be returned to the factory and if found defective will be repaired or replaced free of charge, solely at the discretion of Farris Engineering, ex-works our factory. No charge for labor or other expense incurred will be allowed, as the liability of Farris Engineering is measured by the refund price of the defective product only. All warranties are based on the product being used within the range recommended and does not cover damages or defects due to normal wear and tear, misuse, alteration or neglect. The purchaser shall determine the suitability of the product for use and assumes all risks and liabilities in connection therewith. This warranty does not cover the performance of valves tested at site on test equipment that is not to the same technical standard as that used by the manufacturer.

Any special testing or documentation requirements * As a customer service, we verify your sizing and selection. To do this, we must have this information. Parts Replacement Valves If an exact replacement valve is required, then the valve type, size and serial number must be specified to ensure proper dimensions and material being supplied. If a specific valve is obsolete, a recommendation of the current equivalent will be made if possible. Spare Parts When ordering parts, use part names as listed in the bills of materials. Specify valve type, size and serial number. If the serial number is not available, the original Farris factory order number will help us supply the proper part and material. Springs Order as an assembly to include spring with upper and lower spring buttons. Specify valve type, size, serial number, set pressure and backpressure, if any. Note: If valve modification or set pressure changes are required, consideration must be given to correct the nameplate and other data. 1 General Notes: 1. Valves with inlet flanges available on application. Consult the factory. 2. The 4200 Series uses a carbon steel open bonnet for all temperature ranges.
4 Features and Benefits Open bonnet design: Ensures proper spring cooling for stability and alignment. One piece guide: Ensures precise alignment of valve components. Low stem bearing point: Ensures accurate transmission of spring forces to the disc for greater seat tightness. Temperature equalizing disc: Quickly conforms to any nozzle distortions experienced during a relief cycle and also assists in maintaining positive sealing. Heavy stainless steel lock screw studs: For positive retention of adjusting ring positions. Full nozzle design: For longer life and ease of maintenance. Nozzle easier to remove and service than designs using semi-nozzle construction. FAST Centers Look for the FAST tag on every 4200 series safety valve. This tag is your assurance that every valve has been assembled and tested to the highest quality standards. Farris FAST Centers also provide ready access to replacement parts and valves as well as factory trained personnel who can assist you with all of your pressure relief valve requirements. 2

12 Sizing Information The 4200 Series valves are built in conformance to Section I of the ASME Boiler and Pressure Vessel Code. They are primarily intended for use on steam boilers where ASME Code Section I stamped valves are required. Sizing is per equation listed below. The orifice areas listed in this catalog are actual areas and should not be confused with API effective orifice areas shown in most process valve catalogs. For Steam Service A = W s 51.5P K d K sh Where: A = Required orifice area in square inches. P = Relieving pressure in pounds per square inch absolute = set pressure + overpressure psig. ASME Code Section I: Overpressure is 3% of set pressure or 2 psig, whichever is greater P = 1.03 x set pressure psig OR P = set pressure + 2 psig psig. ASME Code Section VIII: Overpressure is 10% of set pressure or 3 psi, whichever is greater P = 1.10 x set pressure psig OR P = set pressure + 3 psig psig. W s = Required steam capacity in pounds per hour K d = Coefficient of discharge, 02 for all services. K sh = Steam superheat correction factor. See table below. K sh Superheat Correction Factor Set Press psig Saturated Steam Temp. F. Total Temperature in Degrees Fahrenheit
