化工部阀门标准测机构，而应用于阀门产品的计算机应用软件也是相当齐全：既可通过分析手段对新产品和新技术的先进性能进行理论分析与预测，又可采用实验的方法预测结果进行验证，根据统计数据同时验证其分析方法的正确性，以此得出一系列有效的阀门性能和技术特性的分析方法，以此类方法应用于后续阀门技术的开发，以至在降低研发成本，其研究成果更具实效。
好多企业阀门产品虽获得不少国家专利，但好多专利仅为实用专利，技术含量不高，好多专利仅在结构上作了部分改进，没有实质性改进发明。
有的还存在仿制和抄袭，由于好多阀门用户多年停留于使用传统产品，因而好多产品内外结构多年没有实质性改进与提高。
再如目前我国阀门产品驱动执行机构控制水平也差。
国内生产的阀门配套驱动执行机构，其性能和控制水平仅是国外20世纪90年代水平，其动作灵敏度差，自动化控制能力和可靠性总体水平相对滞后。
与此其信号采集、信号比较、信号放大、信号返回等一系列控制能力落后于发达国家的水平。
其实就技术水平而言，常规阀门的设计和材料应用上，我们与国外知名企业相比，并没有多大的差距，在制造工艺上也没有不可逾越的鸿沟，那差在什么地方？但以实际情况就是差在认真两字上，一、产品[衬里截止阀]的详细资料：产品型号：J41J/FS型产品名称：衬里截止阀产品特点：法兰连接手动截止阀,直通式截止阀,连接手动截止阀二、截止阀概况：一、截止阀是指关闭（阀瓣）由阀杆带动并沿阀座中心轴线做升降运动的阀门，在管路上主要用来接通或截断管路中的介质，但不能做节流用。
二、设计规范遵循GB 12233、GB 12235、ANSI B16.34标准。
三、驱动方式手动、齿轮传动、气动（常开或常闭）、电动。

Parker Solenoid Valves with Manual OverrideFor equipment test and power outageMarkets• Industrial equipment process• Energy (solar power)• Agriculture• Transportation Applications• Instrumentation equipment• Analyzers and diagnostic equipment • Process control• Lubrication equipment• Pilot valve actuation• Mobile fuel shut off• Textile and dry cleaning equipment • Irrigation systems Benefits• Locking manual override• Compact design• Compatible with all coils in valve family • Brass or Stainless with NBR seals • 2" NPT valves have a slow close feature to prevent water hammer Technical Data• 2-way and 3-way configurations • Flow factors up to 38.6• Operating Pressure up to 230 psi • Available in 1/4" to 2" NPT brass or 1/4" NPT stainless steelProductParker's locking manual override option for 2-way and 3-way stainless steel and brass solenoid valves provide more application solutions. Solenoid valves are designed to start and stop the flow of media when directed by an electrical signal. When electricity is not available to shift the valve into the ‘on’ position, a mechanical method must be used. These valves have this option. Instances where non-electrical valve function may be required include checking a system during start up, trouble shooting a problem or operation in a power failure.For industrial processes where manual override is required, Parker solenoid valves with manual override are the ideal solution.Parker’s Fluid Control Division has always offered 4-way pneumatic valves for valve actuation with manual override. Now, manual override is an option in the multi-mediasolenoid valves as well.CAT MANOVR0915 Dec. 2015© 2015 Parker Hannifin Corporation.
