Materials
Forged or rolled bars, sourced and stocked only from high quality mills.
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
