GYL-20400 series non balanced cut off type control valve


                  GYL-20400 series balanced cut off type control valve, according to the different closing pressure conditions, the valve core arc type seal design and automatic center positioning design structure of the two kinds of pressure relief valve, effectively can ensure the sealing joints closely cooperate, ensure that ANSI CLASS 6 leakage level requirements. Single valve seat sealing surface, can be used to open or close the flow of the two flow mode, the configuration of different thrust of the actuator, can greatly improve the closure of the pressure difference. According to the high pressure closed, can choose a decompression type double seat. Two kinds of different internal parts of the selection, so that the use of GYL-20400 series of non balanced cut off type control valve cover including low temperature, high temperature and high pressure difference.
