1、Designation: F 1030 86 (Reapproved 2008)An American National StandardStandard Practice forSelection of Valve Operators1This standard is issued under the fixed designation F 1030; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the

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

3、ated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only.1.3 This standard may involve hazardous materials, opera-tions, and equipment. This standard does not purport toaddress all of the safety concerns associated with its use. It isthe res

General Requirements4.1 General requirements apply to all t

6、ypes 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 fi

7、tted 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 Positioning of the valve by either the local or remoteactuators shall not void the ability of any other act

8、uator 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 shal

9、l 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 w

10、herever 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 Requir

11、ements 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. Manualoperation shall override power operation of the valve. Stem nutdriven electric, pneumatic

12、, 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 n

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

Electric Valve Operators7.1 The valve operator shall be powered by the shipsservice power system. Critical valve operators may

16、 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

17、or through a reach rod transmission with flanges inaccordance with ANSI B16.5.7.2.1 Renewable stem nuts shall be provided for stem 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 ope

18、rate. Forweather deck applications 104F (40C) is considered stan-dard. For machinery spaces 122F (50C) is standard.7.4 The motor 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

19、 Class Fwith Class B temperature rise. The motor shall have built-inthermal and overload protection.7.5 The operator shall transmit 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 bearing

20、s shall be used throughout.7.6 The gear system shall not permit backdrive through theoperator upon interruption of electric power.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

21、 explosion proof andsubmersible, with submersible electric connections where ser-vice conditions dictate.8. Pneumatic Valve Operators8.1 Position indication of pneumatic-actuated valves shallbe accomplished by a self-indicating air cock and a pressuregage or other acceptable means installed in the a

22、ctuating line asclose to the control board as possible.8.2 Systems with a maximum allowable working pressure inexcess of 150 lb/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 sh

23、all not be affected by back pressure in the system.8.4 Suitable drains shall be provided at low points of pipingsystems.9. Hydraulic Valve Operators9.1 Each hydraulic operating system shall be self-containedincluding the necessary piping and a reservoir tank for theoperating fluid. Back pressure in

24、the system shall not effect theproper functioning of any system component.9.2 Systems using hydraulic motors shall have a designpressure 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 press

25、ureof the piston or diaphragm and shall have relief valve protec-tion.9.4 The hydraulic fluid used shall have a flashpoint of notless 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 operat

26、ion of thesystem through the entire temperature range to which it may besubjected in service.9.6 Motors shall be installed directly on valves or through agear system to produce the necessary valve speed or torque.9.7 Pumps and control cocks at remote operating stationsshall be mounted on panels with

27、 the reservoir tank locatedabove the suction of the pumps. Four-way plug cocks shall bearranged to transit pressure for opening and closing the valves.Cocks shall have a neutral position to allow for expansion ofoperating oil that may be trapped in the system and to preventinadvertant operation.9.8

28、The minimum number of pumps at a remote operatingstation for a system shall be in accordance with Table 2.9.9 Multiple pumps shall be connected in parallel.TABLE 1 Handwheel Diameters and Tee-Wrench Handle LengthsTorque,lbfftTee-WrenchHandleLength,in.
