This will likely adversely affect the performance of thevalve and any nearby peripheral equipment. Therefore, if the valve is tobe energized for periods of longer than 30 minutes at a time or if duringthe hours of operation the energized period per day is longer than the de-energized period, we advise using a 0.4 W or lower valves, such as theSY series, or a valve with power-saving circuit.3.12 Effect of back pressure when using a manifoldWarning•Use caution when valves are used on a manifold because an actuatormay malfunction due to back-pressure.•Special caution must be taken when using 3 position exhaust centrevalve or when driving a single acting cylinder.

For this reason, use caution that the valveswith external pilot specification cannot be pressurized from exhaustport [3(R)]. As compared with the types which do not integrate the backpressure check valve, C value of the flow rate characteristics goesdown. For details, please contact SMC.•Do not switch valves when A or B port is open to the atmosphere, orwhile the actuators and air operated equipment are in operation. Theback pressure prevention seal may be peeled off, which may cause airleakage or malfunctions. Use caution especially when performing atrial operation or maintenance work.4 Settings4.1 Changing the connector entry directionCaution•Since lead wires are attached to the connector, excessive pulling ortwisting can cause broken wires or other issues. Also, take care thatlead wires are not pinched when installing the connector.•If an excessive force is applied on the connector in the ‘LOCK’ position,the connector block may be damaged. Connector lead wires maybreak If the switch is in the ‘FREE’ position during operation.

Confirm that the air is released toatmosphere.•After installation and maintenance, apply operating pressure andpower to the equipment and perform appropriate functional andleakage tests to make sure the equipment is installed correctly.•If any electrical connections are disturbed during maintenance, ensurethey are reconnected correctly and safety checks are carried out asrequired to ensure continued compliance with applicable nationalregulations.•Do not make any modification to the product.•Do not disassemble the product, unless required by installation ormaintenance instructions.7.2 Fitting assembly replacementRefer to catalogue for additional information.Figure 10.7.3 Manifold expansion and replacement parts•When disassembly and assembly are performed, air leakage mayresult if connections between blocks and tightening of the end block’sholding screw, is inadequate. Before supplying air, confirm that thereare no gaps, etc. between blocks, and that manifold blocks aresecurely fastened to the DIN rail. Then supply air and confirm that thereis no air leakage before operating.•Tighten the DIN rail holding screw to the recommended torque of 1.4N∙m.•Refer to catalogue for additional information and replacement parts.8 Limitations of Use8.1 Limited warranty and disclaimer/compliance requirementsRefer to Handling Precautions for SMC Products.Warning8.2 Cannot be used as an emergency shut-off valveThis product is not designed for safety applications such as anemergency shut-off valve. If the valves are used in this type of system,other reliable safety assurance measures should be adopted.8.3 Holding of pressure (including vacuum)Since valves are subject to air leakage, they cannot be used forapplications such as holding pressure (including vacuum) in a system.8.4 Intermediate stoppingRefer to Handling Precautions for 3/4/5 port Solenoid Valves.8.5 Air returned or air/spring returned spool valves•The use of 2-position single valves with air returned or air/springreturned spools has to be carefully considered.•The return of the valve spool into the de-energized position dependson the pilot pressure. If the pilot pressure drops below the specifiedoperating pressure the position of the spool cannot be defined.•The design of the system must take into account such behaviour.•Additional measures might be necessary. For example, the installationof an additional air tank to maintain the pilot pressure.

脉冲式电磁阀据兰州市环保局新闻发言人介绍，兰州市七里河区与安宁区污水处理厂已经建成，日处理能力20万吨，计划今年9月正式投入使用。

兰州市今年还将投资3800万元，对七里河区、安宁区污水管网进行扩建，目前工程已开工建设，预计9月底完成。

工程完工后将减少黄河七里河区段、安宁区段污水排放口117处。

发言人表示，兰州今后仍将继续加大污水治理力度。

兰州市的目标是到2010年将全市污水处理率提高到70%以上，全市化学需氧量排放总量控制在4.67万吨以内，比“十五”末消减13.4%。

兰州地处黄河上游地带，是黄河唯一穿城而过的省会城市。

黄河兰州段全长152公里，其中流经兰州市区45公里，为兰州市提供了主要的生产和生活用水。

黄河流经兰州后，水质却大大下降，主要受兰州城市生活污水和工业废水污染。

2006年，兰州全市废水排放量为超过1.6亿吨，其中工业废水排放量约为0.42亿吨，占25%；生活及其他污水排放量1.2亿首页>>产品中心>>ZBF22Q自保持电磁球阀一、概述：ZBF22Q-6～250型电磁球阀是二位二通自保持自动阀门，其开(关)阀由内、外部回路共同控制，当开(关)阀信号接通时，线圈励磁，产生旋转力矩，带动球阀阀芯转动，阀芯转到全开(关)位置时，阀内部机构自断电，阀保持开(关)位置。

本阀采用球面密封，它比传统线密封的电磁阀密封性能更好，使用寿命更长；其线圈因瞬时带电，节省电能，延长使用寿命。

ZBF22Q-6～250型电磁球阀适用空气、油、水等无强腐蚀性流体。

工作时，对流体的流向不作要求，对流体的进、出口压力不作要求，对介质的清洁度不作严格要求，可广泛用于电力、石油、化工、冶金等部门，用以远程控制管道中介质的流通与中断。

二、典型用途：1、控制电站冷却用水2、电站密封用水3、电站供油管道油路的开断。

三、特点:1.本阀采用球阀结构，增强密封性能，延长使用寿命。

2.线圈瞬时带电，避免传统电磁阀因长期带电易烧线圈而无法工作。

SMC电磁阀SY5120-5LZD-01适用环境和介质SMC电磁阀SY5120-5LZD-01是用来控制液压系统中油液的流动方向或调节其压力和流量的，因此它可分为方向阀、压力阀和流量阀三大类。

一个形状相同的阀，可以因为作用机制的不同，而具有不同的功能。

压力阀和流量阀利用通流截面的节流作用控制着系统的压力和流量，而方向阀则利用通流通道的更换控制着油液的流动方向。

这就是说，尽管SMC电磁阀存在着各种各样不同的类型，它们之间还是保持着一些基本共同之点的。

SMC电磁阀SY5120-5LZD-01适用环境
a、环境的高低温度应选在允许范围之内，如有超差需作特殊提出。

b、环境中相对湿度高及有水滴雨淋等场合，应选防水电磁阀。

c、环境中经常有振动，颠簸和冲击等场合应选特殊品种，例如船用电磁阀。

d、在有腐蚀性或爆炸性环境中的使用应优先根据安全性要求选用耐发蚀。

e、环境空间若受限制，请选用多功能电磁阀，因其省去了旁路及三只手动阀且便于在线维修。

SMC电磁阀SY5120-5LZD-01适用介质：
1、气液态或混合状态分别选用不同品种的电磁阀。

2、介质温度不同规格产品，否则线圈会烧掉，密封件老化，严重影响寿命。

介质温度应选在电磁阀允许范围之内。

3、介质粘度，通常在50cSt以下。

若超过此值，通径小于15mm 订高粘度电磁阀。

4、介质清洁度不高时都应在电磁阀前配装反冲过滤阀。

介质若是定向流通，且不允许倒流。
