pneumatic thin fat through engine valve dual oriented structure, equipped with multi spring actuator. Has the advantages of compact structure, surface light, sensitive action, low loss, pressure drop description allows a large pressure difference, valve capacity, flow characteristics of Trichosanthes really, convenient maintenance and so on, can use dry harsh working conditions. Especially suitable for the valve pressure difference, workplace requirements without leakage. This series of products are the standard type, adjust the cut-off valve, bellows seal type, jacket type insulation and other varieties. Nominal grade products are PN10, 16, 40, 64; body diameter range of DN20~300. Application of fluid temperature from -196 ℃ ~+560 ℃ range of different grades. Leakage star standard with IV or VI. Flow characteristics such as linear or percentage. A variety of different specifications can be selected.
