Designation:F103086(Reapproved 2014)1An American National StandardStandard Practice forSelection of Valve Operators1This standard is issued under the fixed designation F1030;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEThe Keywords Section was editorially added in November 2014.1.Scope1.1 This practice provides guidance in the selection ofmanual and power-actuated valve operators.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard may involve hazardous materials,operations,and equipment.This standard does not purport toaddress all of the safety concerns associated with its use.It isthe responsibility of the user of this standard to establishappropriate safety and health practices and determine theapplicability of regulatory limitations prior to use.2.Referenced Documents2.1 ANSI Standards:2B16.5 Pipe Flanges and Flanged Fittings3.List of Valve Operator Types3.1 Manual Operators:3.1.1 Handwheels.3.1.2 Tee-wrenches.3.2 Electric Operators:3.2.1 Stem Nut Driven.3.2.2 Handwheel Driven.3.3 Pneumatic Operators:3.3.1 Stem Nut Driven.3.3.2 Handwheel Driven.3.4 Hydraulic Operators:3.4.1 Stem Nut Driven.3.4.2 Handwheel Driven.4.General Requirements4.1 General requirements apply to all types of valve opera-tors.4.2 Operating terminals shall be accessible during all ser-vice conditions but shall not constitute an obstruction inworking spaces.4.3 Valve controls that are not immediately identifiable as toservice shall be fitted with name plates.4.4 Valve operating stations shall be fitted with a valveposition indicator unless valve position is obvious for theservice intended(full open or full closed),or valve is classifieddamage control smaller than 112in.(38.1 mm).4.5 Positioning of the valve by either the local or remoteactuators shall not void the ability of any other actuator toposition the valve.4.6 All valves,regardless of size,shall be readily operableby one man in a reasonable and limited time period,eitherthrough a manual or power-actuated valve operator.5.Manual Valve Operators5.1 Material for handwheels and tee-wrenches for casualtyor damage control shall be either malleable iron,ductile iron,or steel.5.2 Portable valve wrenches shall be labeled and stored nearthe valve operating station.Valve operating wrenches shall fitand turn(to open and close)deckbox operator covers.5.3 Valves shall be located to prevent the necessity forratchet wrenches wherever possible.Ratchet wrenches are,however,permitted where valve location prevents completewrench rotation.5.4 Handwheel diameter and tee-wrench handle length,based on the system torque at the operating station,is presentedin Table 1.6.Requirements for Power-Actuated Valve Operators6.1 Requirements for power-actuated operators apply toelectric,pneumatic,and hydraulic valve operators.6.2 All power-actuated valves,except for valves withintanks,shall have a means for local,manual operation.Manual1This practice is under the jurisdiction of ASTM Committee F25 on Ships andMarine Technology and is the direct responsibility of Subcommittee F25.11 onMachinery and Piping Systems.Current edition approved Nov.1,2014.Published November 2014.Originallyapproved in 1986.Last previous edition approved in 2008 as F1030 86(2008).DOI:10.1520/F1030-86R14E01.2Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 operation shall override power operation of the valve.Stem nutdriven electric,pneumatic,and hydraulic operators shall returnto the power mode after manual reset.6.3 To prevent personnel injury during remote actuation ofthe valve,the manual handwheel shall be either the solid disktype,or it shall have a spoke cover plate or handwheelenclosure,or it shall disengage so that it does not rotate.6.4 Valve actuators in critical systems may be provided withan energy storage system with sufficient capacity to cycle thevalve once(from the initial position to the opposite and return).7.Electric Valve Operators7.1 The valve operator shall be powered by the shipsservice power system.Critical valve operators may be addi-tionally powered by an emergency power system.7.2 Handwheel acting operators shall consist of the electricmotor,gearing,limit and torque switches,reversing starter andpilot lights,and permanently mounted handwheel to form acomplete self-contained unit to be mounted directly on thevalve or through a reach rod transmission with flanges inaccordance with ANSI B16.5.7.2.1 Renewable stem
