The E.ON CHP facility is one of the largest of its type in the UK, generating 130MW of electricity for local residents and capable of supplying around 500 tonnes of steam every hour for two nearby soda-ash production plants in Winnington and Lostock. Make-up boiler feed water from the River Dane is cooled Gate Valves and pre-treated to remove any algae or silt, then passed through one of six filters before being sent to a holding tank. The filters are cleaned by air scouring and backwashing to remove any material blinding the filter. The original butterfly valve used in the backwash process could not provide a steady flow rate, causing media to be lost through the filters. Filter media had, therefore, to be replaced or refilled at an average cost of ?3,500 a year. The downtime for this maintenance also affected the plant’s ability Globe Valves to meet its steam requirements. E.ON installed an eight-inch Fisher Control-Disk rotary valve to replace the original butterfly valve. The new valve has dramatically improved backwash flow control without compromising capacity at peak demand. Since it was installed, the plant has not lost any filter media or experienced any downtimePlug Valves due to water filter problems. Neil Price, improvement and performance coordinator at E.ON, said the new valve also delivers, when 100% open, a flow rate adequate to meet the water plant demands, without restrictions. “Its Balance Valves performance and reliability led to savings of ?3,500 a year and enabled us to improve our customer service.” According to Emerson, the Fisher Control-Disk valve’s disk profile and equal-percentage characteristics that enable it to adapt to changing process conditions and to provide control Forged Steel Valves over a wide range. The valve is said to provide between 15% and 70% travel without compromising capacity, whereas standard butterfly valve designs offer only 25% to 50% of travel.

卫生防护中心的设施大肠杆菌是其在英国最大的同类型之一，为当地安全阀居民和蒸汽约500吨，每小时附近两苏打灰宏利和洛斯托克生产厂供应能力130毫瓦的电力。化妆内河戴恩锅炉给水冷却和预处理，以消除任何藻类或淤泥，然后通过一个闸阀过滤器之前6个被发送到一个控股坦克通过。该过滤器是一种利用空气和冲刷，以消除反冲洗过滤器的任何材料致盲。原来蝴蝶阀滤池反冲洗过程中使用不能提供一个稳定的流量，导致媒体将通过过滤器丢失。滤料有，因此，需要更换或在3,500英镑一年的平均成本加气。此维修停机时间也影响了工厂的能力，以满足其蒸汽的要求。 E. ON公司安装了一个8英寸费希尔控制磁盘旋转阀，以取代原来的蝶阀。新的阀门已显着提高的截止阀需求又不损害高峰反冲洗流量控制能力。由于这是安装，工厂并没有失去任何过滤介质或遇到任何停机由于净水器的问题。尼尔价格，改进和大肠杆菌表现协调员说，新的阀门还提供，当100％公开，流速足以止回阀满足自来水厂的要求没有限制。 “它的性能和可靠性导致每年3500英镑的储蓄，使我们能够改进我们的客户服务。” 据艾默生，费雪控制磁盘阀的磁盘配置和平等的百分比特性，使其能够适应不断变化的工艺条件，并蝶阀提供了范围广泛的控制。该阀是说，提供15％至70％的能力，而又不影响旅游蝶阀柱塞阀的设计标准，只能提供25％至50％的旅行。
