Curtiss-Wright Farris - Model 2600 Series & 2600L Series -Process Valve
Farris Engineering's 2600 and 2600L Series process valves are meticulously designed to safeguard equipment against excessive overpressure across various services including air, gases, steam, and liquids. The design ensures these valves can withstand maximum piping strain without compromising functionality or causing leakage. This is achieved through superior strength in the valve body, positive alignment, a high-strength disc design, and optimal seating surface finishes which all coalesce to enhance tightness and reduce potential thermal distortions. The streamlined nozzle design simplifies maintenance by allowing easy removal and assembly. General specifications cover a broad range from 1 x 2 inches to 20 x 24 inches in size, with orifice areas ranging from 0.15 sq in to 176.7 sq in. They are capable of handling set pressure ranges from 15 to 6000 psig (1 to 413 barg) and temperature ranges from -320 to 1500°F (-195 to 815°C). Suitable for multiple services and constructed from robust materials including carbon steel, stainless steel, various alloy steels, Monel, Hastelloy C, Duplex, and NACE-compliant materials, these valves are engineered for reliability and efficiency.

PRESSURE RELIEF VALVE - DESIGN & OPERATION
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.
STRENGTH & TIGHTNESS
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
optimum seating surface finish.
NOZZLE DESIGN
The Farris full nozzle pressure relief valve design incorporates a nozzle shape to provide:
- A high stable flow coefficient.
- Greater strength to resist possible discharge piping strains.
- Wrenching provisions on raised face nozzles where they will not interfere with the flow path.
The superior design allows easy maintenance by simplifying nozzle removal and assembly.
