The VSO Max is the latest expansion of the Precision Fluidics Divisions VSO family of proportional valve products into a higher flow range. The company says its offers 18 per cent more flow while using 25 per cent less power than the nearest competitive valve on the market (Fig. 1). ASCO Numatics, a leading manufacturer of comprehensive fluid automation, flow control, and pneumatics solutions, has introduced the ASCO 411 Series miniature solenoid valve that offers up to twice the life of competing products plus higher flow rate performance (Fig. 2). The new valve is ideal for applications in pharmaceutical, medical, analytical, and instrumentation products. "Now, original equipment manufacturers (OEM) can receive the benefits of longer life, smaller size, lighter weight, higher flow, and lower power consumption - all in one miniature solenoid valve," said Robert W Kemple, Jr, executive vice president, sales and marketing - Americas, ASCO Numatics. "The 411 Series dramatically reduces the design tradeoffs and compromises engineers must make in applying valves to their products." The 411 Series' novel plunger design significantly reduces wear on the poppet and is resistant to internal elastomer swelling that can disrupt performance. The new valve has been tested to exceed 500 million cycles in normal operating conditions, which the company says makes it the longest-lived, most reliable product of its kind on the market. ASCO has increased the valve's flow rate by 12-15 per cent over previous models, and the maximum operating pressure differential has been improved. "These factors will enable engineers to design products with greater operating speeds, higher pressures, and smaller volumes," said Kemple. The new valve family incorporates a smaller, lighter weight plastic body that also achieves a 12- 15 per cent overall weight reduction when compared to stainless steel and brass-bodied valves. This makes the 411 Series a good choice for miniaturised and portable medical devices and pharmaceutical products. Lower power consumption means the valve also is attractive for use in battery-powered applications. In addition, ASCO says it is the only miniature solenoid valve that is fully compliant with RoHS regulations. "The 411 Series is assembled and tested in a specially built Class 100 cleanroom that is dedicated to miniature solenoid valve production," Kemple said. "Our valve's exceptional reliability and its flexibility to address a wide range of specifications and operating characteristics provide the OEM with the widest variety of design options." For its part, Burkert has combined dynamic performance with compact design and a highly precise proportional valve in its new Liquid Flow Controller (LFC). The company says that the integration of sensor, control electronics and proportional valves into a single compact device make the LFC ideally suited for applications requiring the fully-automatic metered dosing of small amounts of liquids. It complements the company's portfolio of compact fluid control devices for the measurement and dosage of liquids with a nominal flow rate of 10-600ml per minute and a span of 1:10. The LFC is based on the successfully proven and tested software, hardware and mechanics of the MFC series. Thanks to its compact design, the controller can be installed in difficult locations, such as directly behind angled piping. Due to its fast and accurate flow rate measurement, the LFC can be used in a large number of industrial applications such as process engineering, packaging, surface finishing, coating, filling or machine tool construction. Some examples of potential applications are: heat treatment by carburisation or endogas generators; the testing of fuel cells; the coating of surfaces; and the cooling of machine tools. Burkert says the big advantage of the LFC is that it is a one-stop system solution combining reliability and functionality with a truly convincing cost-performance ratio. Vortex has launched its new Quantum series Orifice Gate. It has fewer parts than the original Vortex Orifice Gate, along with other benefits including weather resistance, superior sealing capabilities, fast and easy maintenance, self-cleaning, wear compensating seals and a narrow profile. Using a patented Vortex design, the company says that the Orifice Gate valve offers significant advantages over traditional knife gates and butterfly valves. "Other gate valves, knife gates, slide gates, and butterfly valves rely on soft rubber seals that erode away or tear when handling dry bulk material. The Vortex Quantum series Orifice Gate valve eliminates these problems by using 'live loaded' hard polymer seals," it says. Oliver Twinsafe is set to increase the efficiency of its double block and bleed valve production having ordered a bespoke test rig from Ventil Test Equipment in Holland.

Smaller valves focus on high performance;是由提供的阀门新闻，中文译文仅供参考，以下提供站内导航搜索：

译文：较小的高性能阀门重点
精密射流部派克汉尼汾，在运动和控制技术的全球{ldz}，宣布了其{zx1}的微型比例阀释放，{zd0}出差的。这种高流量比例阀流量比200slpm提供更多的同时，耗电不到2瓦。 美国临床肿瘤学会纽曼帝克，一个全面流体自动化，流程控制的 {lx1}制造商，气动解决方案，推出了411系列微型的ASCO电磁阀，它提供高达两倍的竞争产品的性能以及更高的流量（图2）生活。新的阀门是在制药，医疗，分析和仪器仪表应用的理想产品。 “现在，原始设备制造商（OEM）可以得到较长的寿命，体积小，重量轻，高流动的好处，并降低功耗 - 在一个微型电磁阀一切，说：”罗伯特W肯普尔，小，执行副总裁销售和营销 - 美洲，美国临床肿瘤学会纽曼帝克。 “411系列大幅降低了权衡和妥协的设计工程师必须在应用阀门他们的产品。” 411系列小说柱塞设计大大降低磨损，耐的阀芯和弹性体的内部膨胀，可以破坏性能。新的 阀门已通过测试，超过正常工作条件下，该公司表示，使它成为最长寿，最可靠的同类产品市场上的5.0亿次。 ASCO上增加了百分之12-15阀门的流量较以前的型号，{zd0}操作压力差已有所改善。 “这些因素将使设计工程师有更大的运行速度，更高压力的产品，体积更小，说：”肯普尔。 新阀系列采用了更小，重量轻塑胶机构，也达到了12 - 百分之总重量减少15相比，不锈钢 和黄铜健全阀门。这使得411系列为小型化和便携式医疗设备和医药产品的良好选择。低功耗意味着阀门也吸引了在电池供电的应用。此外，美国临床肿瘤学会说，这是{wy}的微型电磁阀，是xx符合RoHS规范。 “411系列是装配和在一个专门建造100级无尘室，专门向微型电磁阀生产测试，”肯普尔表示。 “我们的阀门的出色的可靠性和灵活性，以解决一系列规范，操作范围广等特点提供了最广泛的各种设计方案的OEM。”就其本身而言，布尔克特结合了紧凑的设计和高度xx的在其新的液体流量控制器（消失模）比例阀的动态特性。 该公司表示，该传感器集成，电子控制装置和一个紧凑型设备比例阀使消失模理想的要求全自动液体少量的水表计量应用的理想选择。它补充了公司的紧凑型的测量和一个10 -六○○毫升，每分钟和一个1:10跨度额定流量液体的 用量流体控制设备组合。在消失模是成功的基础上经过验证和测试软件，硬件和力学的MFC系列。由于其紧凑的设计，控制器可以安装在，困难的地方，如后面直角管道。 由于其快速，准确的流量测量，消失模可以用在诸如过程工程，包装，大量工业应用表面处理，涂层，灌装或机床的建设。潜在应用的一些例子有：热处理carburisation或endogas发电机，燃料电池的测试;的表面涂层，以及机床冷却。 布尔克特说，在消失模大好处是，它是一个一站式系统解决方案相结合的一个真正令人信服的成本效能比的可靠性和功能。 涡已经推出了一系列新的量子口门。它比原来的涡口门少部分，随着包括耐候性，优良的 密封性能，速度快，维修方便，自洁等优点，磨损补偿密封和狭窄的形象。用涡设计专利，该公司表示，孔闸阀提供超过传统的刀门和蝶阀具有明显的优势。 “其他闸阀，刀门，滑门，蝶阀依靠软橡胶密封，撕裂时，剥夺或削弱干散货装卸材料。孔板的涡量子系列闸阀xx了使用'活加载'硬聚合物密封这些问题， “它说。 奥利弗Twinsafe设置，以增加其双块阀门生产效率和流血后下令从Ventil测试设备定制的测试台在荷兰。 “在国家的{zxj}的电脑设备拥有二七五吨夹紧载荷，并已专门为奥利弗的双块和流血的产品。Ventil都非常出色，说：”工程总监克雷格弗尼沃尔。 “从他们的{dy}个站点访问期间，我们已经发展了他们的钻机已经非常有帮助的信件。” “这些钻井平台是流行的测试单一隔离阀门，但数字基带阀有更多的议席，使软件运行测试 是{wy}的Twinsafe。本港阀门大小也是作为我们的夹持负荷需求的考虑比提供的高Ventil的标准范围，“他补充说。 该钻井平台将xx自动化的奥利弗Twinsafe贯穿整个测试周期，静水和天然气，在一个按钮，并采用了真空填充体系，有效地吸收到阀体内，而不是空洞水抽入水。 该钻井平台将容纳阀孔尺寸从2英寸到14英寸，包括8合二五??英镑，12和14日在一千五英镑在六零零磅压力等级。 “这台全数字化提供了一个报告服务等不仅会大大提高我们的输出，它也将提供另一种为我们的客户可追溯水平，”结束弗尼沃尔
