Maximum blowdown of 5% to 15% regardless of service.1 • A built-in lift stop ensures stable performance. • Balanced design in “C” and “D” orifices nullifies the effects of back pressure on set point. ASME Code Certification • Manufactured in conformance to Section VIII of the ASME Boiler and Pressure Vessel Code for air, steam, and liquid 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 6500 psig with orifice areas from 0.068 to 0.573 sq. in. • Standard valves have MNPT inlet X FNPT outlet. Optional female thread, flanged, socket weld, welding nipple, and sanitary connections available. Maximum Selection of Materials • Standard construction includes 316 stainless steel body, trim and spring, with carbon steel bonnet. • Optional materials include Monel®, Hastelloy C®, and materials suitable for NACE service. General Note: Blowdown on liquid service may slightly exceed 15% in certain applications. 1 Teflon is a registered trademark of the DuPont Company.
