GYL20230 type low temperature control valve

                  ◆L20230-type low-temperature control valve, seat-oriented imbalance trim structure, excellent dynamic stability and seat sealing performance. The sensitivity of stem seal bellows seal with standard stuffing box seal double measures the movement of the stem to ensure absolute tightness and stability in cryogenic conditions from cryogenic medium. Body cryogenic low temperature resistance of austenitic stainless steel or aluminum-magnesium alloys, and related materials to ensure that the valve body in the intensity of the cryogenic conditions. Seat oriented imbalance quick release the internals structure, DN100-caliber following selection the outside pumping bonnet structure cryogenic valve online maintenance very convenient. Conditions to choose a balanced trim, or noise reduction, anti-cavitation and special valve cage pieces.
