High Pressure Floating Ball 3 Piece 28
Size Range
1/4”- 8” (DN8-DN200)
Pressure Range
Class 2500, Bar 420, Psi 6000
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 a sufficient safety factor during operation. A special hybrid seat design is comprised of a metal housing and polymer insert machined as a single unit, which provides bubble tight shut-off (Rate A) combined with lower operating torque.
Materials
Forged or rolled bars, sourced and stocked only from high quality mills.
High Δp (differential pressure)
Up to 414bar (6,000psi) full Δp class 2500 depend on series and size.
Robust design
Pressure containing parts are in compliance with ASME B16.34.
A one-size-up stem made of high tensile material complies with ASME B16.34 and API 6D
(#6D-1278) for drive train requirements provides a sufficient safety factor during operation.
A special hybrid seat design provides a higher metal seat stiffness and bubble tight shut-off
(Rate A) combined with lower operating torque compared to equivalent similar valve solutions.
Pressure tested
Designs are burst-proof tested for 4 times the maximal working pressure.
Designed and tested per EN 14432:2014
Type test certified by DNV-GL (for part of the series)
