產(chǎn)品型號：SMQ型
產(chǎn)品名稱：氣動球閥(調(diào)節(jié)型/開關(guān)型)、(法蘭式、對夾式、臺灣三片式)
產(chǎn)品特點：氣動調(diào)節(jié)球閥,是在引進(jìn)國外先進(jìn)技術(shù)的基礎(chǔ)上進(jìn)行特殊設(shè)計，精心制造的產(chǎn)品。采用智能控制與定位，與電氣閥門定位器配套，輸入4-20mADC信號及0.4~0.7MPa氣源即可控制運轉(zhuǎn)，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(qiáng)等優(yōu)點。特別適合于介質(zhì)是粘稠、含顆粒、纖維性質(zhì)的場合。可廣泛應(yīng)用于石油、化工、教學(xué)設(shè)備、輕工、高壓設(shè)備、制藥、造紙等工業(yè)自動控制系統(tǒng)中，作遠(yuǎn)距離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禁發(fā)網(wǎng)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.
