A relief valve works by reducing the pressurized fluid via an open path. As fluid begins to rise, the force from that pressure is applied to the bottom of the spool or poppet. Which then encourages the relief valve to open slowly while maintaining pressure downstream. Relief valves experience pressure rise from load pressure, back pressure, and the energy required to flow through the valve.
Relief valves are based on two types of operation: pilot-operated valves and spring-loaded valves. Programmed to open and close via a spring mechanism, spring-loaded valves open automatically when the pressure reaches an excessive level, releasing the material inside the vessel. The typical spring-loaded valve can be controlled in numerous ways, such as a remote or control panel.
Pilot-operated valves work by combining the primary main valve with self-actuated auxiliary pressure relief valves, also known as the pilot control. The pilot control responds to the pressure in the system and then decides the opening and closing of the main valve.
A relief valve is designed to release excess pressure that builds up in equipment and piping systems. Their purpose is to prevent significant damage that may occur to the system or even cause injury to operators. In the case of an overpressure event, a relief valve can release elevated force before it becomes extreme; it does so by using a steel spring to automatically open when the pressure is detected unsafe for the application. It’s vital the valve is consistently maintained and operates at all times to ensure it offers complete protection.

Accurately size and select a pressure relief valves for various process applications using SizeMaster™, a web-based engineering software tool. The SizeMaster™ software brings unprecedented integration of recognized and generally accepted good engineering practices (RAGAGEP) to the task of sizing and selecting pressure relief valves.
Self-registration is required to access the SizeMaster™ Software.
New and registered users can access the software by clicking here »
SizeMaster includes catalog information for Farris 2400, 2600, 2700, 3800, 6400/6600, 4200, 1890, 1896, and 4700 series pressure relief valves, including black and white cross-section dimensional drawings. The registered user can select and customize a candidate Farris model number, SizeMaster™ will ensure a valve is suitable for the supplied process parameters (such as a liquid-trim valve for a vapor scenario), and on-line help is available to assist in the determination of each of the digits of the Farris model number configuration. SizeMaster™ can manage the sizing and selection work-flow process for jobs/plants, from request for quotation through order generation.
Whether the user is quoting safety valves for a large-scale Job/Plant or performing a single yet fast Quick Size option, SizeMaster™ makes the task of sizing and selecting pressure relief valves straight-forward and globally accessible. The design of this web-based software allows for the development team to automatically deploy updated versions of the tool to remain up-to-date with the latest changes in industry best practices and new product features and offerings.
If you need assistance related to our sizing software, please contact a software development specialist at [email protected] and discuss how we can address your needs.

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 which checks selected conditions and any intermediate calculations against the constraints of industry standards, informing the user of any non-compliance issues it encounters. Using supplied sizing conditions and application-specific details, suitable candidate valve(s) are cross-checked against their appropriate temperature and pressure tables including any backpressure constraints. Once the software determines the orifice area required to relieve the supplied overpressure scenario(s), SizeMaster™ recommends an optimum Farris pressure relief valve series and orifice size. The user can further customize its materials, soft goods, and other options and accessories to meet their facility and device needs.
All application details, sizing equations, and other overpressure scenario parameters can be generated in different data formats (i.e. XLS, HTML, PDF, etc.) and extracted from the program.
