The material of the body and bonnet is A6063, and other metal components of the vacuumpart are made of SUS304. The sealing material of the vacuum part is FKM as standard, but this can be changed to other materials (refer to “How to Order”). Confirm whether the fluid to be used is compatible with the materials before use.Grease for vacuum is applied to the sliding part of the vacuum (Fluorine grease: Y-VAC2).2. Select materials for the pilot pressure piping and fittings whose heat resistance is suitable forthe applicable operating temperature.●Models with auto switch1. Keep the temperature of the switch below 60o C●With heater (thermistor)1. When using a model with a heater, a mechanism to prevent overheating should beinstalled.SelectionCaution●All models1. When controlling valve responsiveness, take note of the size and length of piping, as wellas the flow rate characteristics of the actuating solenoid valve.2. Keep the pilot pressure within the specified range.The specified range of XLG-16, XLG-25 and XLG-40 is from 0.3MPa to 0.5MPa, and that is for XLG-50, XLG-63, XLG-80, XLG-100 and XLG-160 is from 0.4MPa to 0.5MPa.3. Keep within the specified range of the pilot pressure.●High temperature type1. If using gases that cause a large amount of deposits, heat the valve body to prevent depositsin the valve.Mounting● All models1. In high humidity environments, keep the valve packed until the time of installation.2. For models with switches, secure the lead wires so that they have sufficient slack, withoutany unreasonable force applied to them.3. Perform piping so that excessive force is not applied to the flange sections. When there isvibration from heavy objects or attachments, etc., fix piping so that vibration will not apply torque directly to the flange section.4. Vibration resistance allows for normal operation of up to 30 m/s2 (45 to 250Hz), butcontinuous vibration may cause a decline in durability.Arrange piping to avoid excessive vibration or impacts.●High temperature type (temperature specification / H0 H4 H5)1. In models with a heater (thermistor), take care not to damage the insulation components of thelead wires and connector section.2. The set temperature for models with a heater should be established without any drafts or heatinsulation. It will change depending on conditions such as heat insulation measures and the heating of other piping. Fine adjustment is not possible.3. When installing heater accessories or mounting a heater, check insulation resistance at the actual operating temperature. A current leakage breaker or fuse should be installed.4. If the valve is to be insulated, only the body should be insulated, excluding the bonnet part.5. In models with a heater, when the heater is in operation, the entire valve becomes hot.Be careful not to touch it with bare hands, as burns will result.1. Before mounting, clean the surface of the flange seal and the O-ring with ethanol, etc.2. There is an indentation of 0.1 to 0.2mm in order to protect the flange seal surface, and it should be handled so that the seal surface is not damaged in any way.If the fluid or reaction product (deposit) may cause the valve to become unsafe, the valve should be disassembled, cleaned and re-assembled by an operator who has sufficient knowledge and experience (e.g. a specialist).1. When removing deposits from the valve, take care not to damage any part of it.2. Replace the bonnet assembly when the valve is approaching the end of its service life.* For details regarding endurance cycles, please reference Section 5 of this Operation manual titled Period and scope of warranty . (pages 12)3. If damage is suspected prior to the end of the service life, perform early maintenance.4. SMC specified parts should be used for service.

Thesethermistors self regulate their temperature byswitching the resistance at certain criticaltemperatures, so a separate temperature controller isunnecessary.If the temperature of the PTC heaters fitted exceeds200o C, then it may fail. The maximum operatingtemperature for the valve is 150o C. If the heatertemperature is over 200o C or valve temperature isover 150o C, please use thermostat to control theheaters to prevent overheating.With PTC type heaters, there is an initial surge ofcurrent (inrush current) after the power is supplied. These inrush current will reduce overtime. If multiple heater assemblies are used, the inrush current to the heaters will be magnified and care should be taken. When multiple heater assemblies or valves are used, do not apply power to the heater assemblies simultaneously. Keep approximately 30 seconds between applications of power toeach heater assembly. This will allow for incremental spacing to prevent harmful large initial surge.4.4-1.

调压阀维修方法
第1章调压阀维修方法1.1调压阀常识1.正压调压阀SUP侧为进气口，OUT侧为排气口；负压调压阀V AC侧与气泵的吸气口（-0.085MPa）相连，SET侧为真空设定侧。
安装时，注意方向不要装反。
2.当正压调压阀旋钮没有拧紧时（弹簧没有被压缩），出气口就不会有气体冒出。
若出气口没有压力，请先向下拧紧旋钮（旋钮顺时针拧紧，逆时针拧松），看是否可以调节压力。
安装完毕后，需要将锁紧螺母锁紧。
3.当负压调压阀旋钮没有拧紧时（弹簧没有被压缩），真空度为0或接近0，安装完毕后，需要将旋钮压下即可锁紧。
4.正压调压阀和负压调压阀都有两个O型密封圈，拆开后重新安装时，需要注意其方向性。
安装方向可参考图1和图4。
5.正压调压阀顺时针调节时，出口压力增大，反之减小；负压调压阀顺时针调节时，设定真空度变大（向绝对真空变化），反之减小。
1.2故障判断小诀窍1.正压调压阀在正常工作时，在溢流孔一般都会有少量气体流出，用手放在孔周围能明显感觉到气流，当用手把溢流孔堵死时，调压阀出口压力会增大。
若感觉不到有气体冒出，则调压阀有故障；2.正压调压阀在正常工作时，当压力由大调小（逆时针调节）时，溢流孔处会有“丝丝”的声音发出；由小调大（顺时针调节）时，则没有“丝丝”的声音。
若无，则调压阀有故障；3.负压调压阀在正常工作时，从大气吸入口会吸入空气，手放在周围，能明显感觉到有气体被吸入；若无，则调压阀有故障。
1.3调压阀维修方法3100气源组件中的调压阀有：250KPa溢流阀，正压调压阀（70KPa和160KPa），-40KPa 真空调压阀。
对于250 kpa、-85 kpa压力故障，按照BC-5500使用说明书进行处理即可，以下讨论调压阀维修方法。
正压调压阀（70 kpa，160 kpa）的压力故障1．按照使用说明书进行故障处理。
若不能消除故障，请判断故障类型：无法调压（或出口压力为0）、调压阀漏气、压力正常，但机器报压力故障。
2．对于无法调压（或出口压力为0）的情形，拆开调压阀，对阻尼孔和其它比较脏的地方进行清洗。

FESTO减压阀如何调节压力大小
FESTO减压阀如何调整压力大小FESTO减压阀是在管道系统中用于掌控流体压力的紧要装置，常见于给水系统、自然气管道等。
它能够稳定流体压力，确保在肯定范围内保持正常工作压力。
本文将讨论减压阀如何调整压力大小以及当减压阀不能调压时可能的原因。
一、减压阀的工作原理减压阀是常见于液压系统中的一种掌控元件，其重要作用是通过减小压力差，将高压液体在阀芯下游调整为肯定的低压液体。
具体工作原理如下：1、减压阀的主体是由阀体、阀芯以及弹簧等构成的；2、当高压液体从减压阀的口进入时，减压阀芯会受到高压力的作用，向上升起，这个时候，阀的出口处就会显现低压液体；3、当减压阀出口的低压液体使得阀芯回到原位时，减压阀的内部高压室与低压室之间的压力差就被减小了，进而实现了减压的目的。
二、减压阀的手动调整方法手动调整方式是的调整减压阀的方法。
调整时可以通过旋转减压阀的手柄或杆，使得阀芯的位置发生变动，进而转变减压阀的阀门开度大小，从而实现转变液压系统压力的目的。
具体操作步骤如下：1、先确认液压系统处于正常运行状态，且减压阀安全工作环境，避开显现不安全情况；2、找到减压阀的手柄或杆，沿着减压阀的轴线旋转或推拉手柄或杆；3、通过察看压力表的显示，调整减压阀的位置，使系统压力实现你需要的值。
三、FESTO减压阀的自动调整方法FESTO减压阀节更加方便，不需要人工干涉，能够依据系统需求自动调整压力。
自动调整方式一般通过压力掌控器、流掌控器以及掌控电路等构成，可以对液压系统进行精准掌控。
具体操作步骤如下：1、在液压系统中添加自动掌控器，并将减压阀的输出流量接入自动掌控器；2、设置需要的压力值和流量值，通过掌控电路掌控减压阀的开度从而实现自动调整的目的；3、对于采用比例掌控的系统，可通过调整比例阀的开度来实现更精准明确的掌控效果。
四、FESTO减压阀常见故障及排出方法FESTO减压阀在使用过程中可能会显现一些故障，如漏油、压力不稳定等，这时候需要依据具体问题采取相应的排出措施。
