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.

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。

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。

第五章RMG、IGA、英思卓美型调压阀第一节RMG型调压阀基本原理一、RMG214型调压阀和RMG704型安全截断阀RMG704是先导式安全截断阀，RMG214是直接作用自立式调压阀为直接作用自立式调压阀。

分输站的生活用气高压段都安装了该型阀门。

（一）安全截断阀介绍该阀门主要由以下几个部分组成，分别为：主阀体、平衡阀、阀杆总成、滚珠机构、控制器、引压管线、压力转换装置。

阀门各零部件材质：主阀体：铸钢控制器：铸铝膜片：氟化橡胶密封：丁晴橡胶主阀内部零件：钢、铝、黄铜最大入口压力：100bar设计温度：-15—+60℃反应时间：0.1—0.3S高压保护压力设定范围：0.04—90bar低压保护压力设定范围：0.01—40bar功能：调压阀下游压力高于规定值时，切断供气。

功能原理介绍：在下游气体压力高于设定值时，阀门控制器的双膜机构在气体压力作用下向上移动，放大阀的开度增大，控制器内气流增大，压力升高，高压气流进入压力转换装置，推动活塞和顶杆向外平移，使滚珠离位，阀杆总成处于自由状态，在关闭弹簧的作用下，完成阀门的关闭动作。

阀门的打开完全靠手动完成，首先打开平衡阀，平衡阀瓣前后的压力，平衡后向下按动开阀按扭，听到咔嗒声且按不动后证明阀门已经打开。

锁紧机构原理介绍：锁紧机构由滚珠和阀杆套组成，阀杆上加工了一台阶。

在阀门处于全开的位置时，滚珠在压力转换装置的顶杆的推力下卡在阀杆台阶上，使阀杆不能自由移动；当下游压力超过设定值时顶杆向外平移，推力为零，滚珠离位，阀杆处于自由状态。

RMG670控制器的功能原理介绍：该控制器由双膜机构和设定装置组成。

正常情况下放大阀处于关闭状态，双膜结构受到来自下游气体的压力作用和设定弹簧的弹力作用，压力转换装置中无带压气流。

当调压阀下游压力超高时，气流压力作用在双膜结构上，高于设定弹簧的弹力，双膜结构向上移动，放大阀打开，带压气流进入压力转换装置。

阀门的设定是通过改变控制器设定弹簧的压缩量来完成的，设定时要调整外圈弹簧，顺时针调整为增大设定值，反时针旋转为减小设定值。
