详细介绍
产品型号：SMD型
产品名称：气动蝶阀（调节阀/开关型）、（对夹式、法兰式）
产品特点：气动蝶阀，是在引进*进技术的基础上进行特殊设计，精心制造的产品。蝶阀配行程限位开关、电磁阀、三联件及0.4-0.7MPa气源可实现开关操作，并送出二对无源触点信号指示阀门的开关。采用智能控制与定位时，与国产电气阀门定位器配套，输入4-20mADC信号及0.4-0.7MPa气源即可实现智能控制，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。可广泛应用于石油、化工、轻工、制药、造纸、汽车等工业自动控制系统中作远距离集中控制或就地控制。
Model: SMD-type
Product Name: pneumatic valve （control valve / switch type）, （wafer type, flange type）
Features: the company that produced precision pneumatic butterfly valve, is the introduction of foreign advanced technology, based on specially designed, well-made ??products. Butterfly with a travel limit switch, solenoid valve, FRL, and 0.4-0.7MPa gas source switching operation can be realized, and sent two pairs of passive contact signal indicating valve switch. The use of inligent control and positioning, and supporting domestic electric valve positioner, input 4-20mADC signal and 0.4-0.7MPa gas source to achieve inligent control, to realize the pressure, flow, temperature, level and other parameters of the adjustment. It is a compressed air powered, driven spool valve stem in the valve body rotation 90 ℃, can fully open – fully closed the action. Sealing performance of the product into its metal sealing and soft sealing. With a compact, compact, reliable operation, good sealing, easy maintenance, easy installation, flexibility and other advantages. Can be widely used in petroleum, chemical industry, light industry, pharmaceuticals, paper, automotive and other industrial automatic control system for centralized remote control or local control.
