产品型号：SMQ型
产品名称：气动球阀(调节型/开关型)、(法兰式、对夹式、台湾三片式)
产品特点：气动调节球阀,是在引进国外先进技术的基础上进行特殊设计，精心制造的产品。采用智能控制与定位，与电气阀门定位器配套，输入4-20mADC信号及0.4~0.7MPa气源即可控制运转，实现对压力、流量、温度、液位等参数的调节。它是以压缩空气为动力，阀杆带动阀芯在阀体内转动90°可以实现全开—全闭的动作。该产品按其密封性能分为金属密封与软密封。具有结构紧凑、体积精小、运行可靠、密封性好、维修容易、安装方便、适应性强等优点。特别适合于介质是粘稠、含颗粒、纤维性质的场合。可广泛应用于石油、化工、教学设备、轻工、高压设备、制药、造纸等工业自动控制系统中，作远距离集中控制或就地控制。
Model: SMQ-type
Product Name: pneumatic valve (modulating / switch type), (flange, the clip-on, Taiwan's three-piece)
Features: pneumatic control valve, is the introduction of foreign advanced technology, based on a specially designed, well-made ??products. The use of intelligent control and positioning, and supporting electric valve positioner, input 4-20mADC signal and 0.4 ~ 0.7MPa air to control operation to achieve the pressure, flow, temperature, level and other parameters of the adjustment. It is a禁发网址pressed air powered, driven spool valve stem in the valve body can rotate 90 ° fully open - fully closed the action. Sealing performance of the product into its metal sealing and soft sealing. With a reliable operation, good sealing, easy maintenance, easy installation, flexibility and other advantages. Is particularly suitable for medium thick, containing particles, fiber nature of the occasion. Can be widely used in petroleum, chemical industry, teaching equipment, light industry, high-pressure equipment, pharmaceuticals, paper and other industrial automatic control system for centralized remote control or local control.
