Farris Pressure Relief Valves
Protecting people, equipment, and processes from overpressure starts with pressure relief technology you can depend on.
Farris, a Curtiss-Wright brand, provides pressure relief valves engineered for critical overpressure protection across oil and gas, refining, chemical processing, power generation, and other industrial operations.
Tundra Process Solutions provides Farris pressure relief valves across Western Canada, supported by product expertise, local inventory, testing, repair, and certified aftermarket service through the Farris Authorized Service Team (FAST) network.
Why Farris? About the Brand
Engineered for Overpressure Protection
Farris has built its reputation around pressure relief technologies designed to protect critical process equipment when operating pressures exceed safe limits.
With spring-loaded and pilot-operated pressure relief valve technologies, Farris supports a wide range of pressure, temperature, media, and operating conditions.
Backed by Curtiss-Wright, Farris combines valve engineering, manufacturing, and aftermarket support to help facilities manage pressure relief requirements from initial valve selection through testing, maintenance, repair, and replacement.
Pressure Relief Technology for Critical Applications
Farris offers pressure relief valve technologies designed to respond automatically to overpressure conditions, safely relieving pressure before it can damage equipment or compromise process safety.
Spring-Loaded Pressure Relief Valves
Farris spring-loaded pressure relief valves use a mechanical spring to hold the valve closed during normal operating conditions.
When system pressure reaches the valve’s set pressure, the valve opens to relieve excess pressure before automatically closing as conditions return to an acceptable operating range.
Spring-loaded designs are available for a broad range of industrial services, including applications involving high set pressures, elevated temperatures, and varied process media.
Pilot-Operated Pressure Relief Valves
Farris pilot-operated pressure relief valves use system pressure and a pilot control to manage the opening and closing of the main valve.
This design allows the valve to operate close to set pressure while maintaining a tight seal during normal conditions. Depending on the application, pilot-operated configurations can provide either snap-acting or modulating relief.
Pilot-operated designs can be particularly well suited to applications where back pressure, inlet pressure loss, reduced leakage, or operation close to set pressure must be considered.
Find the Right Pressure Relief Valve
Pressure relief valve selection depends on more than pressure alone. Process media, temperature, back pressure, relieving capacity, operating conditions, applicable codes, and installation requirements all influence valve selection.
Tundra’s valve specialists can help evaluate these requirements and identify the appropriate Farris pressure relief valve for your process.
