HP Floating Ball 3 Piece up to 400°C (750°F)

Z28P


Size Range
1⁄4”- 6” (DN8-DN150)
Pressure Range
Class #2500, 414 bar, 6000 psi

-60°C to 400°C (-76°F to 752°F) Trunnion valves only -46°C to 327°C (-40°F to 620°F)

High Pressure High Temperature Class 2500, full differential pressure for sizes up to and including 2″ (DN50), differential pressure of up to 255 bar (3700 psi) for sizes 2½” (DN65) and above with hybrid seats.

Pressure containing parts are in compliance with ASME B16.34, for wall thickness, design type-tested for burst testing of four times the pressure rating for 5 minutes. A one-size-up stem made of high tensile material complies with ASME B16.34 and API 6D for drive train requirements which provides sufficient safety factor during operation. A special hybrid seat design is comprised of a metal housing and polymer insert machined as a single unit provides bubble tight shut-off (Rate A), combined with lower operating torque.

Cryogenic High Pressure Ball Valve

Materials:

  • Stainless Steel, alloys, Carbon Steel – selected to meet temperature and application. ASME
    B16.34 listed cast or forged material for the valve body and ends.
  • Surface treatments & coatings – LTPN, HVOF Cr₃ C₂ (Chromium Carbide), HVOF WC-Co
    (Tungsten Carbide) and Stellite.

Robust design:

  • Pressure containing parts are in compliance with ASME B16.34 (with modifications for
    some series).
  • Leak rate to EN12266-1 Rate B (factory tested) is achieved by accurate grinding and
    lapping processes.
  • Constant preloading of ball/seats set obtained by Inconel 718 Belleville spring.

Pressure tested:

  • Designs are burst proof tested for 4 times the maximal working pressure.
  • Designed and tested per testing & acceptance criteria ANSI/FCI 70-2.
