產(chǎn)品型號：SMD型

產(chǎn)品名稱：氣動蝶閥（調(diào)節(jié)閥/開關(guān)型）、（對夾式、法蘭式）

產(chǎn)品特點：氣動蝶閥，是在引進*進技術(shù)的基礎(chǔ)上進行特殊設(shè)計，精心制造的產(chǎn)品。蝶閥配行程限位開關(guān)、電磁閥、三聯(lián)件及0.4-0.7MPa氣源可實現(xiàn)開關(guān)操作，并送出二對無源觸點信號指示閥門的開關(guān)。采用智能控制與定位時，與國產(chǎn)電氣閥門定位器配套，輸入4-20mADC信號及0.4-0.7MPa氣源即可實現(xiàn)智能控制，實現(xiàn)對壓力、流量、溫度、液位等參數(shù)的調(diào)節(jié)。它是以壓縮空氣為動力，閥桿帶動閥芯在閥體內(nèi)轉(zhuǎn)動90℃，可以實現(xiàn)全開——全閉的動作。該產(chǎn)品按其密封性能分為金屬密封與軟密封。具有結(jié)構(gòu)緊湊，體積精小，運行可靠，密封性好，維修容易，安裝方便，適應(yīng)性強等優(yōu)點?？蓮V泛應(yīng)用于石油、化工、輕工、制藥、造紙、汽車等工業(yè)自動控制系統(tǒng)中作遠距離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.
