Since the early 1940s, the Farris Engineering unit of Curtiss-Wright Flow Control has designed and produced a wide range of spring-loaded and pilot-operated pressure relief valves. Used as safety devices, Farris pressure relief safety valves prevent over pressurization of vessels, pipelines, and equipment. Farris manufacturing is a company recognized as a leader in the hydrocarbon processing, refinery, petrochemical, natural gas production/transmission, pharmaceutical, and general processing industries worldwide. Their safety valves and other PRV hardware can be found across the globe – from the U.S. to the U.K. and S. America to China.

A pioneer in the field, the Farris Engineering company created many safety pressure relief products that remain industry standards. Integrating its core hardware technology with the information age, Farris developed computer software to assist customers in the sizing and selection of safety valves for all manner of piping and equipment. A recent reorganization of manufacturing plants and processes maximized production effectiveness to position the business unit at the forefront of the industry, with service and delivery second to none. If you are looking for an effective, high-quality safety valve and engineering expertise for any and all pressure relief management questions – look to the safety valve companies Farris Engineering and North American Machine Works.

Farris is a renowned supplier in the design and production of a wide range of spring-loaded and pilot-operated pressure relief valves. They are used as safety devices to prevent over-pressurization of vessels, pipelines, and equipment. When a plant is equipped with Farris’ spring loaded and pilot operated PRV hardware, it’s protected by 70 years of manufacturing experience.

Farris pressure relief valves have earned a name in the industry for being trusted, top quality and long-lasting. When it comes to ensuring your machinery or equipment is protected from overpressure, Farris pressure relief valves are a great option.

The term pressure relief valves references both safety valves and expansion relief valves. The valve opens when it’s necessary to relieve pressure on a system.

While some basic components and activations in relieving pressure off a system may differ depending on the specific types of Farris relief valves, each main valve is intended to be 100% effective in keeping your equipment running safely and protect employees working nearby. Farris valve types range from flanged to spring loaded, threaded, pilot operated, and much more.

With Farris, a trustworthy valve is only part of our promise. Farris provides customers with total pressure relief management solutions that support a facility’s entire lifecycle, transforming the way you ensure plant safety:

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.
