1、Designation: F1030 86 (Reapproved 2018) An 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 y

2、ear 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.1. Scope1.1 This practice provides guidance in the selection ofmanual and power-actuated valve operators.1.2 The values sta

3、ted 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 does not purport to address all of thesafety concerns, if any, associated with its us

4、e. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principle

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 immediat

8、ely 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 112 in. (38.1 mm).4.5 Posi

9、tioning 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

10、. 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 cl

11、ose) 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

12、 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.1This practice is under the jurisdiction of ASTM Committee F25 on Ships andMarine Technology and is th

United StatesThis international standard was developed in accordance with internationally

15、recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.16.2 All power-actuated valves, except for valves withintank

16、s, shall have a means for local, manual operation. Manualoperation 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

17、 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 i

18、nitial 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, geari

19、ng, 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 ASME B16.5.7.2.1 Renewable stem nuts shall be provided for s

20、tem actingoperators instead of the permanently mounted handwheels.7.3 The operator shall be suitable for marine service ratedfor the ambient temperature in which it will operate. Forweather deck applications 104F (40C) is considered stan-dard. For machinery spaces 122F (50C) is standard.7.4 The moto

21、r shall be one of the following:7.4.1 Single Phase, 115 Vac, capacitor start, capacitor runor,7.4.2 Three Phase, 460 Vac.7.4.3 Both types shall have insulation of Class B or Class Fwith Class B temperature rise. The motor shall have built-inthermal and overload protection.7.5 The operator shall tran

22、smit power from the motor to thevalve stem, valve handwheel, or reach rod transmission systemthrough a bevel gear, worm gear, or planetary gear system. Ballor roller bearings shall be used throughout.7.6 The gear system shall not permit backdrive through theoperator upon interruption of electric pow

23、er.7.7 The closing and opening operation shall be regulated bymeans of a travel-activated device and a torque-activateddevice as a backup.7.8 The operator enclosure shall be explosion proof andsubmersible, with submersible electric connections where ser-vice conditions dictate.8. Pneumatic Valve Ope

24、rators8.1 Position indication of pneumatic-actuated valves shallbe accomplished by a self-indicating air cock and a pressuregage or other acceptable means installed in the actuating line asclose to the control board as possible.8.2 Systems with a maximum allowable working pressure inexcess of 150 lb

25、/in.2(10.3 bar) shall be designed with a surgetank or other acceptable means of pulsation dampening.8.3 The system shall be designed so that proper functioningof any unit shall not be affected by back pressure in the system.8.4 Suitable drains shall be provided at low points of pipingsystems.9. Hydr

26、aulic Valve Operators9.1 Each hydraulic operating system shall be self-containedincluding the necessary piping and a reservoir tank for theoperating fluid. Back pressure in the system shall not effect theproper functioning of any system component.9.2 Systems using hydraulic motors shall have a desig

27、npressure of sufficient magnitude for the intended use.9.3 Systems with piston- or diaphragm-type hydraulic op-erators shall have a design pressure equal to the design pressureof the piston or diaphragm and shall have relief valve protec-tion.9.4 The hydraulic fluid used shall have a flashpoint of n

28、otless than 199.4F (93C) for pressures below 150 lb/in.2(10.3bar) and 316.4F (158C) for pressures of 150 lb/in.2andabove.9.5 The hydraulic fluid shall be suitable for operation of thesystem through the entire temperature range to which it may besubjected in service.TABLE 1 Handwheel Diameters and Te
