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
10、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 handl

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

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 h
15、andwheel 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 ini
16、tial 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
17、, 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 nuts shall be provided for ste
18、m 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 motor
19、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 transm
20、it 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 power
21、.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 Opera
22、tors8.1 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/i
23、n.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. Hydrau
24、lic 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 designp
25、ressure 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 not
26、less 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.9.6 Motors shall be installed direct
