Dimensions & Weights Other Farris Engineering Valves Introduction Designed to provide customers with the widest selection of sizes, orifices and construction materials, Series 2700 meets the exacting demands of the process industry. Superior Design single design handles air, steam, vapor and liquid services. Maximum interchangeability of parts affords easy maintenance and lower costs. Fixed blowdown design simplifies testing and repair. Maximum blowdown of 5% to 15% regardless of service. 1 built-in lift stop ensures stable performance. Balanced design in C and D orifices nullifies the effects of back pressure on set point. SME Code Certification Manufactured in conformance to Section VIII of the SME Boiler and Pressure Vessel Code for air, steam, and water service. Capacities certified by The National Board of Boiler and Pressure Vessel Inspectors. Optional O-Ring Seat Design O-ring seat design available for maximum seat tightness. Teflon available at higher pressures to provide the same zero bubbles per minute leakage as elastomer O-ring seats. Comprehensive Product Line Set pressures from 15 psig to 500 psig with orifice areas from 0.0 to sq. in. Standard valves have MNPT inlet X FNPT outlet. Optional female inlet thread, flanged, socket weld, welding nipple, and sanitary connections available. Maximum Selection of Materials Standard construction includes 31 stainless steel body, trim and spring, with carbon steel bonnet. Optional materials include Monel, Hastelloy C, and materials suitable for NCE service. 1. Blowdown on liquid service may slightly exceed 15% in certain applications.

Warranty ll products manufactured by Farris Engineering are warranted free of defects in material and workmanship when used within the range recommended for a period of one year after installation or eighteen months from delivery. When authorized, any defective product may be returned to the factory and if found defective will be repaired or replaced free of charge, solely at the discretion of Farris Engineering, ex-works our factory. No charge for labor or other expense incurred will be allowed, as the liability of Farris Engineering is measured by the refund price of the defective product only. ll warrantees are based on the product being used within the range recommended and does not cover damages or defects due to normal wear and tear, misuse, alteration or neglect. The purchaser shall determine the suitability of the product for use and assumes all risks and liabilities in connection therewith. This warranty does not cover the performance of valves tested at site on test equipment that is not to the same technical standard as that used by the manufacturer.

3 Numbering System Selecting and specifying Farris pressure relief valves is simple using the numbering system that follows. Each digit of the type number has a distinct significance. The digits describe the basic valve series, orifice, seat design, inlet temperature range, body, bonnet and spring material, inlet type and pressure rating. 27 D 2 3 H M 2 0 /S4 Series Number Orifice rea 27 US Customary Units Sq.

5 2700 Series Balanced Design Complies with SME Boiler & Pressure Vessel Code, Section VIII Bonnet Vent K b (Gas) K w (Liquid) Back Pressure Correction Factor Do you have variable back pressure? Can t use a balanced bellows design? Farris has the solution with the Series 2700 Balanced Design pressure relief valve. The balanced effect is achieved by isolating the upper valve chamber and eliminating any back pressure build-up in the bonnet effecting valve set pressure. These valves are available in 1/2", 3/4" and 1" inlet sizes with a 1" outlet and two orifice areas. Pressure ranges from 15 to 0 psig, standard soft seat design. Flanged and welded inlet and outlet connections are available with the same material options as the standard design.
