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.

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 If a specific valve is obsolete, a recommendation of the current equivalent will be made if possible.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
