Frequently Asked Questions — Oil & Gas Valves

What standard governs pipeline ball valves for oil and gas?+
Pipeline ball valves in oil and gas must comply with API 6D (Specification for Pipeline and Piping Valves). This covers design, testing, inspection, and documentation requirements including double block and bleed (DBB) capability, fire-safe design, and anti-blowout stem design.
What does NACE MR0175 mean on a valve datasheet?+
NACE MR0175 (ISO 15156) specifies the materials and hardness limits for metallic components in sour service (H2S-containing environments). For valves, this means the body, trim, and fastener materials must not exceed HRC 22 hardness and must be in the correct heat-treated condition. All components in contact with sour fluids must be NACE compliant.
What is a trunnion-mounted ball valve and when is it required?+
A trunnion-mounted ball valve uses a secondary mechanical support (the trunnion) to hold the ball in place, so line pressure does not create excessive seat contact force. This allows lower operating torques, better sealing at both low and high pressure, and is required for all pipeline valves DN 4" (100mm) and above per API 6D. Floating ball valves are used for smaller sizes and lower pressures.
Do you supply fire-safe certified valves?+
Yes. All our valves for hydrocarbon service are available with API 607 (soft-seated) or API 6FA (API 6D pipeline) fire-safe certification. Fire-safe design ensures the valve maintains acceptable leakage levels during and after a fire test, preventing loss of containment in fire scenarios.
Can you supply actuated ESD valve packages?+
Yes, we supply complete actuated valve packages — valve + actuator (pneumatic, hydraulic, or electric) + positioner + solenoid valve + limit switches + handwheel override. For SIL-rated ESD applications, we supply SIL 2 or SIL 3 certified packages with partial stroke testing (PST) capability.
What is the typical lead time for API 6D valves?+
Standard API 6D ball and gate valves in common sizes (2"–12", Class 150–600, WCB body) are stocked for immediate dispatch. For larger sizes, exotic alloys, or special design features, lead time is typically 4–8 weeks. Contact our sales team with your complete valve datasheet for a specific lead time and price.
