High Pressure Cryogenic 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 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.
