Technical Requirements4.1 Valve SpecificationsDepending upon the application, the desi
18、gner may select valves to industry, military orspecifically developed specifications. For many military applications, standard industry valves may be usedprovided they meet certain military requirements. (See 4.2.4.) Specifications, standards, and test proceduresrelated to hydraulic directional cont
19、rol valves have been prepared by SAE, National Fluid Power Association,ISO, and some Department of Defense activities. Except for some military specifications, most of thesedocuments are not suitable for procurement of valves but contain requirements that can be incorporated intoprocurement specific
20、ations. For example, the selection of a standardized design interface should be used inorder to have a wide selection of manufacturers and to promote interchangeability. In this recommendedpractice, some of the most applicable government and industry specifications, recommended practices andtest pro
21、cedures are identified. For a more complete listing of valve standards and test procedures see NFPAT3.5.27. NFPA T3.5.49 provides basic guidance for the selection, installation, operation, and maintenance ofhydraulic valves.4.1.1 INDUSTRY STANDARDSMost of the National Fluid Power Association valve s
22、tandards have been adopted asAmerican National Standards and many are technically equivalent to ISO documents._SAE J1783 Reaffirmed MAY2013 Page 2 of 124.1.1.1 Directional Control ValvesThere are no industry specifications that can be directly used to procurevalves. There are ANSI and ISO standards
23、for valve interfaces, electrical connectors and methods fordetermining metering characteristics. In specifying valves, standard mounting and electrical interfacestandards should be identified. In addition, the following information must be provided:a. Maximum operating pressure, rated flow, and maxi
24、mum differential pressure at rated flowb. Fluid to be used (operating temperature range/viscosity)c. Seal materials (particularly for military applications where specific materials are required)d. Spool flow paths and types of operators (This can often best be conveyed by a symbol per ISO 1219.)e. L
25、eakage and other special requirements4.1.1.2 Electrohydraulic ServovalvesThere are several documents that are widely used to defineelectrohydraulic servovalve test requirements. SAE ARP490 is widely used in the aerospace industry.ISO 10770-1 and ISO 10770-2 provide test methods for electrically modu
26、lated hydraulic directional flowcontrol valves. ISO 10372 provides recommended mounting configurations for four and five-portservovalves. The designer should identify the requirements per one or more of these documents, takingcare not to specify conflicting requirements. In addition, the type of inf
27、ormation identified in 4.1.1.1 fordirectional control valves should also be provided.4.1.1.3 Proportional Control ValvesISO 10770-1 and ISO 10770-2 cover both proportional control valves andservovalves.4.1.2 MILITARY SPECIFICATIONS4.1.2.1 General RequirementsThe general requirements that have often
28、been applied to all hydrauliccomponents for Navy ships are identified in MIL-HDBK-2193. This document was originally a MilitaryStandard whose requirements could be invoked by the military; as a Handbook the document is forguidance, Not all the requirements/recommendations in MIL-HDBK-2193 are applic
29、able to eachinstallation but guidance is provided as to when the requirements/recommendations are applicable.4.1.2.2 Directional Control ValvesGeneral requirements for hydraulic directional control valves, specificallydeveloped for Navy submarines are contained in MIL-V-868. Specific configuration v
30、alves of differentsizes with standardized interfaces are defined on MIL-V-868 specification sheets, now cancelled. Whilethese documents may not reflect current Navy requirements, they are an excellent source for generalrequirements for directional control valves. These valves were sub-plate mounted
31、with connector tubesbetween the valves and sub-plates. SAE J24714 has been developed to replace the military specificationfor the connector tubes. In addition, connector tube configurations are available into which restrictor,check and relief valves can be installed. Connector tubes in accordance wi
32、th SAE J24714 should be usedwhenever suitable for applications requiring connector tubes.4.1.2.3 Electrohydraulic ServovalvesGeneral requirements for Navy ship electrohydraulic servocontrol valvesare contained in MIL-V-24722. These general requirements are based to a large degree on SAE ARP490.Speci

34、ments._SAE J1783 Reaffirmed MAY2013 Page 3 of 124.2 Environmental Requirements4.2.1 GENERAL REQUIREMENTSThe general environmental considerations that apply to marine vehicleapplications are identified in SAE J1777.4.2.2 ABOVE DECK APPLICATIONSSpecial precautions must be taken to ensure that the valv
35、e components willsurvive this environment. These components include electrical connectors and internal coils and wiring,fasteners, exposed shifting elements, nameplates, name plate drive screws and valve body and end capmaterial coatings. In many applications, corrosion resistant materials must be s
36、elected for satisfactoryperformance in this environment. In other cases, plating and paint may be used to provide adequateprotection. See MIL-HDBK-2193 for further guidance.4.2.3 BELOW DECK APPLICATIONSProtection for below deck use is usually less restrictive. However, the salt airatmosphere still r
37、equires that external valve components and electrical connectors be protected againstmoisture and oxidation.4.2.4 SPECIAL NAVY REQUIREMENTSFor many Navy and military ship applications, the components must meetrequirements unique to military applications. While not all the requirements identified bel
38、ow apply to everyapplication, they may be invoked for many applications.4.2.4.1 Most hydraulic components, including valves must pass High-Impact Shock requirements. See MIL-HDBK-2193 for references to the applicable requirements. Test requirements and acceptance criteria areprovided in MIL-S-901. 4
39、.2.4.2 For most Navy ships, the equipment must be able to meet the environmental vibration requirements ofMIL-STD-167-1. These requirements do not usually pose a problem for hydraulic valves and are similar tomechanical vibration requirements identified in 4.2.7 that are applicable to all ships.4.2.
40、4.3 Some military applications, such as submarines have very stringent acoustical or noise requirements thatmay be classified. Many directional control valves for use in submarine hydraulic systems utilize specialquieting elements. For valves with acoustic requirements, consult with valve designer w
41、hen specifyingenvelope and porting interface pattern requirements to ensure acoustic requirements can be met. Almostall applications will be subject to environmental noise as discussed in 4.4.1.4.2.4.4 For military ships, electromagnetic interference (EMI) must be minimized to prevent adding to the
42、shipsEMI signature (detectability). This in addition to standard EMI requirements as identified in 4.2.6. It isanticipated that the system will be tested per MIL-STD-461, which specifies requirements for the control ofEMI emissions and susceptibility of equipment and systems installed on Navy ships
43、and submarines. Thevalve control system should not become degraded or malfunction due to EMI susceptibility, and should notcreate significant radiated or conducted EMI emissions.4.2.5 FLUID COMPATIBILITYHydraulic valves, including seals and electrical wiring must be compatible with thesystem fluid.
44、SAE J1778 indicates the compatibility of various seal materials with fluids commonly used inmarine vehicles. MIL-HDBK-2193 contains design guidance on material requirements and an immersiontest for nonmetallic materials to determine compatibility with the various types of fluids.4.2.6 ELECTROMAGNETI
45、C INTERFERENCE (EMI) SHIELDINGThe design needs to isolate the electronic components toprevent system degradation or malfunction due to susceptibility to external EMI sources. The valve controlsystem should not become degraded or malfunction due to EMI susceptibility, and should not createsignificant
46、 radiated or conducted EMI emissions.4.2.7 MECHANICAL VIBRATIONVibration testing requirements for shipboard equipment and machinerycomponents are identified in ISO 10055.
