This series of products are standard, bellows seal type, clip of various brand names of insulation type. Products PN16 nominal pressure level have 64, 40,; Nominal diameter scope DN25-400. Applicable fluid temperature have - 60 ℃ - + 650 ℃ range of different class. Leakage standard for III or IV level. Flow characteristics for linear or percentage. Various variety specification available.
ZMAN pneumatic film ended at two-seater regulator with double oriented structure, match on spring actuators. With compact structure, light weight, action quick, valve capacity, flow characteristic precisely and disassembling convenience etc. Widely used in precise control of gases, liquids, steam medium of process parameters, such as pressure, flow rate, temperature, level to remain in a given value. Especially suitable for pressure difference is bigger, allow leakage also larger and not very clean medium occasion.
