Subsea Check Valves – Technical Data

• Working pressure up to 20,000 psig (1379 bar)
• Maximum external pressure: 6,000 psig (414 bar)
• Cracking pressure: 14 to 26 psig (0.966 to 1.794 bar)
• NBR O-ring for operation from -10 to 250˚F (-23 to 121˚C); other O-ring materials available
• High tensile 316 stainless steel for valve body
• Available to NACE MR0175
• Provides unidirectional flow and tight shut-off for liquids and gases with high reliability. When differential drops below cracking pressure, valve shuts offs (Not for use as relief valve)
