来源：World Pumps Flowserve公司已经开发出了新一款数字阀阀门定位器，此产品被设计用以控制单作用和双作用阀实行机构。Flowserve Logix® 3400IQ Foundation Fieldbus 产品的特点是采用了便于使用者操作的FISCO界面，改动了分压计、压电技术和协同工作能力。同时他可以兼容仍逐一款HART®或者是FoundationFieldbus的分布式控制体系（DCS），同时它可以广泛使用在包括石油、自然气和化工处理等很多领域。 Flowserve公司声称，Flowserve Logix3 400IQ被认为可以适用于现行的许多操作标准。包括FM、CSA、ATEX、FISCO，以及最新的Foundation Fieldbus互动性测试，ITK4.6等。该定位器还可与很多公司包括Honeywell,Emerson,Invensys,Yokogawa和Rockwel生产的DCSs兼容。 “拥有了3400IQ定位器，通过用户本身的界面，校准和调整都可以被敏捷和便捷的完成”，Flowserve流体控制市场部的Kyle Ahlfinger如许说到。与HART和Foundation Fieldbus的兼容性，以及被进一步进步的一些特点都使得3400IQ成为在诸多领域正确阀控制的首选产品。（刘昕 编译） Flowserve launches digital valve positioner Flowserve Corp has developed a digital valve positioner designed to control the position of both single- and double-acting valve actuators with linear or rotary mountings. The Flowserve Logix® 3400IQ Foundation Fieldbus features a FISCO-compliant user interface board, improved potentiometer, piezoelectric technology, and host interoperability. It is compatible with any HART® or Foundation Fieldbus distributed control system (DCS) and is suitable for a wide variety of applications, including oil and gas and chemical processing. The Flowserve Logix 3400IQ is certified to meet many current operating standards, including FM, CSA, ATEX, FISCO, and the latest Foundation Fieldbus interoperability testing, ITK4.6, Flowserve says. The positioner is compatible with most DCSs, including those from Honeywell, Emerson, Invensys, Yokogawa and Rockwell. “With the 3400IQ, all calibration and setup of the positioner can be done quickly and easily through the local user interface,” said Kyle Ahlfinger, vice president, marketing, Flowserve Flow Control. “HART and Foundation Fieldbus compatibility and its enhanced features make the 3400IQ the premier choice for accurate valve control for a wide range of applications.”
