Failure to follow instructions can cause personal injury and/or property damage.This publication may have been revised or updated since this copy was produced. To verify thatyou have the latest revision, check manual 26455, Customer Publication Cross Reference andRevision Status & Distribution Restrictions, on the publications page of the Woodward website:/publicationsThe latest version of most publications is available on the publications page. If your publication isnot there, please contact your customer service representative to get the latest copy.Any unauthorized modifications to or use of this equipment outside its specified mechanical,electrical, or other operating limits may cause personal injury and/or property damage, includingdamage to the equipment. Any such unauthorized modifications: (i) constitute "misuse" and/or"negligence" within the meaning of the product warranty thereby excluding warranty coveragefor any resulting damage, and (ii) invalidate product certifications or listings.To prevent damage to a control system that uses an alternator or battery-chargingdevice, make sure the charging device is turned off before disconnecting the batteryfrom the system.To prevent damage to electronic components caused by improper handling, readand observe the precautions in Woodward manual 82715, Guide for Handling andProtection of Electronic Controls, Printed Circuit Boards, and Modules.Go to /publications for complete instructions (manual 82493).Replacement/Exchange: Replacement/Exchange is a premium program designed for the user who is in need of immediate service. It allows you to request and receive a like-new replacement unit in minimum time (usually within 24 hours of the request), providing a suitable unit is available at the time of the request, thereby minimizing costly downtime.This option allows you to call your Full-Service Distributor in the event of an unexpected outage, or in advance of a scheduled outage, to request a replacement control unit. If the unit is available at the time of the call, it can usually be shipped out within 24 hours. You replace your field control unit with the like-new replacement and return the field unit to the Full-Service Distributor.Flat Rate Repair: Flat Rate Repair is available for many of the standard mechanical products and some of the electronic products in the field. This program offers you repair service for your products with the advantage of knowing in advance what the cost will be.Flat Rate Remanufacture: Flat Rate Remanufacture is very similar to the Flat Rate Repair option, with the exception that the unit will be returned to you in “like-new” condition. This option is applicable to mechanical products only. Returning Equipment for RepairIf a control (or any part of an electronic control) is to be returned for repair, please contact your Full-Service Distributor in advance to obtain Return Authorization and shipping instructions.When shipping the item(s), attach a tag with the following information:• return number; •name and location where the control is installed;•name and phone number of contact person; •complete Woodward part number(s) and serial number(s); •description of the problem; •instructions describing the desired type of repair.

The stress has to be relieved by suitable means, e.g. bellows sections.Due to the design (very slim) and the mounting possibility (installation between two flanges) no forces other than the screw forces at the flanges may affect the valve.Trouble shootingLeak at gate: Clean valve seat and gate seal!Replace gate seal, if damaged!Leak at body: Flanges leaktight?Replace bonnet seal!Screws at bonnet tightened?RepairsContact VAT for repairs or maintenance. The fabrication No. (F08- . . . . . / . . . . ) marked on the valve body has always to be specified. It has to be individually decided whether the work can be performed by the customer or has to be carried out by VAT.All supplies (e. g. compressed air, electrical power) have to be disconnected for removal/installation of the valve from/into the system.Even with disconnected supply, loaded springs and/or air cushions in cylinders can be potential hazards.Keep fingers and objects away from the valve opening!Products returned to VAT for repair have to be free of harmful substances such as e.g. toxical, caustic or microbiological ones. For radioactively contaminated products the customer has to fill in the VAT form «Contamination and Radiation Report» and to send it with the product. The form is available at VAT.

手动阀门使用说明
手动阀门是常用的阀门之一，包括有手动蝶阀、手动闸阀、手动球阀、手动截止阀等等，本文为您介绍一下手动阀门使用说明。
1、手动阀门的操作需要操纵阀门的人员握住手柄或手轮进行操作，不能够借助杠杆和长扳手来开关阀门，避免用力过猛对手柄或手轮造成损坏，更不能暴力操作，避免事故发生。
通常情况下，手柄的长度或手轮的直径小于320mm，只允许单人进行操作；手轮的直径等于或大于320mm时，允许两个人共同操作完成，也可以单人适当借助工具，杠杆或扳手进行操作，但要注意杠杆长度不可超过0.5m。
2、手动闸阀和手动截止阀都是借助手轮进行操作，在阀门完全开启或关闭之后，要回转1/4~1/2圈，让螺纹之间更好的密合，同时也能避免阀门拧得过紧出现损坏。
3、操作手动蒸汽阀门，在开启前要先对管道进行预热，排出管道中的凝聚水；开启阀门的速度要慢，以防水锤现象的发生，对阀门和管道设备造成损坏。
4、常开的手动阀门密封面上，很容易粘上杂质和脏物，在关闭闭合之前，微微开启一条缝，可以让高速流动的介质冲走这些异物，然后再轻轻关闭，提高密封效果。
5、在一些过高温介质的管道中，当手动阀门关闭之后，阀体内温度下降，因为热胀冷缩导致阀件收缩，密封面会出现一些细小的缝隙，阀门会出现泄漏。
在这种情况下，要在关闭手动阀门之后，过一会儿再关闭一次。
Vacuum ServiceA vacuum is defined as pressure below atmospheric pressure at sea level. Atmospheric pressure is usually defined as about 14.70 psia (pounds per square inch absolute), 760 mm Hg (Mercury) absolute, 29.92 inches Hg absolute, or 760 torr. Absolute pressures are defined by the equation shown below:P Absolute=P Gauge+ P AtmospℎereThe American Vacuum Society has defined different states of vacuum as shown in the chart below.Note: High Vacuum and Very High Vacuum levels are very difficult to achieve and are not common vacuum applications. Perfect (or full) vacuum is impossible to obtain):Note: torr rating above is used as an absolute pressure unit. Please use the equation above if given a gauge vacuum unit. 1 torr ≈0.0393 inches Hg absolute ≈0.9999 mm Hg absolute ≈0.0193 psia ≈0.536 in wc absoluteCleaning and LubricationMost vacuum applications require a clean and pure environment. A-T Controls offers a degreasing service. This service can also eliminate potential outgassing (release of dissolved gas from materials).A-T Controls thoroughly cleans all valve parts and lubricates the O-ring with a compatible lubricant. The valves are vacuum packed with desiccant and marked as cleaned for Vacuum Service.Materials for Vacuum50/50 STFE, RTFE, PTFE, CTFE, TFM™-1600, and other filled PTFE based materials are common for floating ball valve and soft seated HPBFV vacuum applications. Both Carbon Steel and Stainless Steel (CF8M and CF3M) are used for body and trim material. Viton®, Buna, EPDM, and PTFE seats are commonly used for RSBFV vacuum applications. PTFE packing and graphite packing can be used in floating ball valves and HPBFVs, however graphite will be rated for a lower level of vacuum (see ratings on the next page).Filled PTFE based materials are generally avoided and not recommended for high temperature vacuum applications (constantly above 400 °F) because of the potential of outgassing at higher temperatures at higher levels of vacuum. For this reason, TFM™-1600 is recommended because of its low-outgassing characteristics and wide range of chemical compatibility.Please consult A-T Controls for material selection for your vacuum application. These parameters are guidelines, and customers are responsible for materials of construction, preparation of the valves for service, and lubricants being compatible with their vacuum application.Vacuum RatingPlease see the table on the next page for vacuum ratings for different series valves. Valves are tested in the closed position. Please note that floating ball valves that do not include our pyramidal stem seal are not rated for vacuum service:Note: Colors represent corresponding vacuum state.
