RISING STEM BALL VALVES API6A & API6D

Standard features

      ·     NO Double Piston Effect (DIB): Process application when required a mechanical energized metal or soft seat prevents loss from process                               contamination or material leakage.

      ·         Stem that is separated from the ball, delivering an force on Helix contour design to axis free trunnion .

·         Large-diameter, axis free trunnions that reduce unit bearing loads and operating torque.

·         Primary metal-to-metal seal.

·         Antistatic device no needed.

·         No need for API6D  Body relief valve for overpressure due to liquid thermal expansion.

·         Bolted construction Top entry that permits disassembly in the field for repairs.

·         Double-barrier stem seals

·         Nickel/TCC HVOF coating for trim parts.

·         Trunnion-mounted ball for ease of operation at high pressure.

·         Automation with fail-safe close or fail-safe open
