farris safety valve series 2600 in stock

Optional balanced bellows design isolates working parts and top-works from fouling or corrosive service, and nullifies the effects of back pressure on valve performance.

Standard O-ring elastomer seat main valve and pilot control minimizes fugitive emissions and allows operation within 95% of set pressure. Materials include *Viton®, Buna N, ethylene propylene, silicone and *Teflon®. Optional materials of construction include complete 316 stainless steel.

Now you can accurately size and select a pressure relief valves for any combination of process applications with SizeMaster™ Mark IV pressure relief valve engineering software. This program for Windows® (all versions) brings unprecedented integration of standard engineering practice to the task of sizing and selecting pressure relief valves.

With SizeMaster Mark IV software, you can define as few as one or as many as 64 different sizing scenarios including blocked flow, fire, thermal and tube rupture, from a scenario matrix grid. Selection of the pressure relief valve is automatically based on the relief area of the worst case scenario. Various Wizards make the most complicated task simple; for instance, the Capacity Wizard allows you to determine accurate vapor generation for vessels of all types.

Quicksize Database Tube Rupture Scenario English/Metric Dimensional Drawings API-Omega 2-phase flow calculations Noise and reaction force calculations Multiple valve sizing Standard Windows user interface functions Developed under ISO 9001-2000 guidelines Supports network database access Database administration tools Interactive product catalog Internal client/project database Complete revision control with definable database access English/metric units definable by job level Import/export capabilities Online help including a variety of tutorials

All sizing equations and selection algorithms are based on ASME Code requirements, API standards and best engineering practice as determined by Farris Engineering. The equations and flow algorithms are internally calculated within an innovative worksheet engine. This worksheet engine also checks parameters and any intermediate calculations against standards’ constraints, letting you know about any non-compliance issues it encounters. All equations, calculations and internal algorithms can be displayed on screen or printed for review.

The engineering worksheet engine also checks your parameters and all intermediate calculations against the standards’ constraints, and it tells you about any non-compliance that it encounters, such as attempting to size a conventional valve when a bellows valve is required.

Once SizeMaster calculates the orifice area required to relieve your process scenarios, SizeMaster guides you through the selection of the appropriate Farris pressure relief valve and its materials and other options.

SizeMaster includes catalogue information for Farris 2600, 2700, 3800, 6400, 6600, 4200, 2800 , and 7200 series pressure relief valves, including their black and white drawings. While you are selecting a Farris type number for a tag, SizeMaster ensures that you don’t pick a valve that is not applicable to your process parameters (such as a liquid-service valve for a vapor scenario), and on-line help is available to assist in the determination of each of the digits of the Farris type number, based on your process scenarios.

From its Quick Size and Capacity Wizards through to its consistently standard Windows user interface, SizeMaster makes the job of sizing and selecting pressure relief valves easy, and its worksheet management and workflow auditing facilities let you ensure that your results are correct.

We carry Farris Valves and parts for air, steam, and water processing operations, as well as the Farris Smart PRV with WirelessHART technology. Our Farris Authorized Service Team (FAST) can conduct pre-installation testing, install your valve, and perform regularly scheduled maintenance to keep your workflow operating at peak efficiency. Should you ever need an emergency repair, just call us – our technicians are available 24 hours a day!

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

4. For a valve in complete stainless steel, add “N4” to suffix. Example: 26HB10-120/N4. For optional complete Inconel bellows, add “N4/SP”. Example: 26HB10-120/N4/SP.

1. Standard seat tightness for “O” ring valves is no bubbles at 90% of set pressure for both conventional and bellows valves. At set pressures of 50 psig and below, leakage test shall

1. All valves supplied with plain caps unless otherwise specified. Standard suffix for type number is “-120”. For other cap construction, refer to page 69.

6. Optional equipment includes: air set device for set pressure testing, extra large lapping glass for valve seat maintenance, spring compression device for set

Farris Engineering , in partnership with Emerson, offers Farris SmartPRv technology, a 2600 Series pressure relief valve PRV equipped with a Fisher 4320 wireless position monitor.

Areas of the plant that had previously been too expensive, too difficult or even impossible to monitor using traditional technology can now be monitored with SmartPRV. SmartPRV also extends the range of field application within Emerson"sSmart Wireless solution network, including coverage of criticals assets. Wireless monitoring of PRVs provides equipped plants with the ability to track and monitor valves in real time, providing immediate feedback during an overpressure event.

Farris’ 3800 Series valves feature an innovative, integrally cast, flanged body with a semi-nozzle design. Series 3800 valves are self-contained units actuated by either the snap-acting or modulating style pilot controls.
