产品指南 - 球阀(1)Product Guide—Ball Valves (1)
True Union (真正的管套接)球阀产品系列True Union Ball Valves—A Family of Products True Union的特点，由Chemtrol独立开发，成为工业塑料阀门行业的革命性变革，现在已经成为所有主要制造商的制造标准。这种设计的目的，是为了使得阀腔，也就是阀体包容所有工作部件，通过退出管套接螺母，易于从管道系统中取出用于维护和更换。Chemtrol的True Union球阀和止回阀的易于维修/更换，具有可互换性，便于销售分配，技术维修，以及可靠的质量的综合原理和特点成为许多工厂和OEM制造商所信奉的标准。
The True Union feature, an exclusive Chemtrol introduction, so revolutionized the industrial plastic valve industry that it has become the standard followed by all major manufacturers. The purpose of the design is to permit the valve cartridge, i.e., the body containing all operational components, to be easily lifted from the piping system for servicing/replacement when the union nuts are backed off. Easy repair/replacement, interchangeability, distribution availability, technical service, and reliable quality are the synergistic rationale many plants and original equipment manufacturers have embraced while standardizing on Chemtrol True Union Ball and Check Valves.
True Union阀门是法兰阀门连接功能在塑料材料阀门上的体现。与法兰连接比较，阀门连接端口的管套接连接具有下述优点：制造成本更低；能够大量生产，并在其它阀门和连接件产品之间可互换，因此具有更加灵活的管道应用机会；易于手工紧固或者拆卸管套接螺母，使得阀门的维修更换更加容易；在环状密封面上精确压缩连接比机械螺栓垫圈密封面更加可靠。
The True Union Valve is plastic’s answer to the function of a flanged valve. In comparison with flanged joints, union connections at the ends of a valve have the following advantages: less costly to manufacture; can be mass produced for interchangeable use on other fitting and valve products, which also present flexible piping opportunities; ease of tightening or removing union nuts by hand makes valve servicing/replacement far more accessible; precise compression on ring face-seals results in greater joint reliability than mechanic-dependent bolted gasket face-seals.
