farris safety valve series 2600 pricelist

Introduction This catalog covers Series 2600, 2600S and 2600L pressure relief valves including the latest infor­ ation available to assist m you in the sizing and selection of the proper valves for your application. Farris pressure relief valves have over a half century of proven performance providing auto­ atic and positive m protection against overpressure in thousands of industrial plants and facilities worldwide. Our earned reputation as “the First Line of Safety” is the result of countless Farris innovations combined with progressive engineering, sound design and high quality...

The Farris Advantage Farris pressure relief valves are designed to automatically protect your equipment against excessive overpressure. Every care is taken in the development, design and production of these valves to ensure complete dependability in performance. Our constant objective is to provide a superior valve that will assure ultimate protection at the lowest cost, both initially and throughout its service life. What is the Farris Advantage? Easy sizing and selection of valves using Farris catalogs and/or SizeMaster™ Sizing and Selection software. A method of specification and...

2600 Series Design Valve Selection This catalog simplifies the sizing and selection of Series 2600 process pressure relief valves. The pressure relief valves are presented here in an easy-to-understand format. Unless otherwise stated, references made to the Code refer specifically to ASME Section VIII, Division 1. Certified Capacity Code Compliance The Series 2600 pressure relief valves have been carefully constructed and tested in accordance with the requirements of the ASME Pressure Vessel Code, Section VIII. Their capacity rating for the applicable fluids is certified by the National...

2600 Series Construction Resistance to Discharge Piping Strains For most pressure relief valves, and particularly for those from which the discharge must be piped away to a remote location, it is almost impossible to keep piping strains away from the valve. The superior Farris pressure relief valve design incorporates several features which allow this valve to take a maximum amount of piping strain without hampering the functional characteristics of the valve or contributing to serious leakage. 1. The threaded connection between the valve nozzle and the valve inlet flange is located low in...

2600 Series Metallurgy Integral Sleeve Guide The Farris pressure relief valve design incorporates an integral sleeve guide (Fig 5), assuring continual positive alignment after the part has been manufactured, and including the same high corrosion resistant properties in the guide flange that are present in the sleeve portion of the guide. The sleeve guide is extended above the top of the guide flange, minimizing the possibility of corrosive or other foreign particles washing onto the guiding surfaces when the valve is relieving or when it is “breathing” as a result of atmospheric temperature...

2600 Series Operation All Stainless Steel Stem Construction The Farris pressure relief valve design features an all stainless steel stem. This construction cost-effectively eliminates dangerous sticking due to galvanic corrosion at the upper guiding point in the spring adjusting screw. The careful design of this upper bearing also ensures proper alignment and optimum freedom from galling and erratic popping. Positive Connection of Parts The Farris design incorporates a positive connection between the valve stem and the stem retainer as well as between the disc and disc holder (Fig 7). These...

2600 Series Operation Steam Jacketing for Better Heat Transfer In modern process plants, it is necessary to keep some valves and lines warm at all times to avoid solidification of the lading fluid and to guarantee the safety of equipment. Farris offers a steam jacket (Fig 8) to substantially increase the rate of heat transfer into the valve and, at the same time, simplify the problem of removing or dismantling the valve for maintenance. This design offers a separate two-piece jacket that installs on a standard valve body. See details on page 71. Simple, Accurate Adjustments The single Blow...

Definitions Safety Valve – an automatic pressure relieving device actuated by the static pressure upstream of the valve, and characterized by rapid full opening or pop action. Used for steam, gas or vapor service. Relief Valve – an automatic pressure relieving device actuated by the static pressure upstream of the valve, which opens in proportion to the increase in pressure over the opening pressure. Safety Relief Valve – an automatic pressure actuated relieving device suitable for use as either a safety or relief valve, depending on the application. Pressure Relief Valve – a pressure...

Type Numbering System Our type numbering system simplifies the selection and specifying of Farris pressure relief valves because the digits that comprise a specific type number have a distinct significance. The digits describe the basic valve series, orifice, seat and internal construction, inlet temperature range, body, bonnet and spring material, inlet flange class and Code liquid design. H Designates high pressure versions. Used for “Q”, “R”, “T”, & “U” orifices only. Series Number Orifice Areas Orifice Letter E BalanSeal with auxiliary balancing piston F BalanSeal with auxiliary...

Farris’s pressure relief valves are designed to automatically protect your equipment against excessive overpressure. The Series 2600 pressure relief valves are designed to function equally well on air, gases, steam, or liquid service.

The pressure relief valve design incorporates several features which allow this valve to take a maximum amount of piping strain without hampering the functional characteristics of the valve or contributing to serious leakage.

The superior strength built into the body of the Farris pressure relief valve to resist these discharge piping strains materially reduces the deflection and distortion in the valve and reduces the leakage encountered, when at times, discharge piping strains become excessive.

The valve is engineered for exceptional tightness because of positive alignment, a high strength disc design, the elimination of thermal distortion and

It is a valve that is designed to detect and prevent changes in pressure which could lead to damage and failure in a number of applications. If the desired pressure is exceeded, the valve releases the excess pressure.
