碳化物在低温下（甚至在高于-29℃时）可能转化为石墨、氧化铁素体，塑性减小等变化。
后面均加以了说明。
使用者需依据说明慎重选择适合自己要求的材质（阀门）。
Material have the possibility of failure in use, and should be checked on a regular basisdepending on fluid within the valve. Carbide at low temperature (or even above - 29 ℃)may be converted to graphite, iron oxide ferrite, reducing the plasticity. The behind aredescribed. According to the instructions,the user need to carefully chose the material that fits their requirements (valve).b.压力温度等级: Pressure-temperature rating压力温度等级额定值是在静态压力下的温度额定值。
请参考第3页工作预防方法部分的P&T额定值。
阀门允许使用温度在-20℃~200℃之间，不允许超过此温度范围，以免发生危险。
Pressure-temperature rating is the temperature rating in the static pressure. Please referto page 3 work prevention part of P&T rating. In order to avoid danger, Valve allows theuse temperature between-20℃to 200℃, and doesn't allow more than this temperaturerange.c.流动性热的扩充: Liquidity thermal expansion当球阀在封闭的条件下工作，阀体内的封闭腔体可能封有流体。
若流体不能被及时释放出来，将会升温膨胀，导致压力边缘失效。
而我们的产品具有球垫压力自动调节功能，能够预防压力增强。
建议用户通过管道系统设计、安装或操作程序等方法来进行预防，以避免阀体内压力超过额定压力值。
When ball valve working in the closed conditions, the valve body of closed cavity couldseal a fluid. If the fluid can not be released in time, it will be heating expansion, leading to the failure of pressure edges. However, our products have the cushion pressureautoregulation, preventing pressure increase. To avoid the valve body pressure exceed the rated value, we recommend that users through the piping system design, installation oroperation procedure and methods for prevention.d.静电影响:Electrostatic effect南京苯邦阀门公司球阀具有抗静电能力，当使用环境连续用电需要预防静电时，阀门应有接地，以使静电能够即时得以释放。
Ball valves have the antistatic ability. When the using environment continuous electricity needs to prevent static electricity, the valve should be grounded, so that static electricity can be released immediately.e.意外火灾预防:Accidental fire prevention通常，球阀的使用应遵守压力温度要求。
如果发生意外火灾时造成的危险较大，建议您选择我们的防火型产品。
此产品已通过API-607认证。
具体请与阀门销售商联系或直接联系我们。
Usually, ball valve should be used in compliance with the pressure and temperaturerequirements. If causing greater risk in the event of accidental fires, it is recommended that you choose our fire protection products. The product has passed the API - 607certification. For details, please contact with the valve sales or contact with us directly.f.液体流速:Liquid velocity当球阀必须经常在高速流体条件下频繁开关时，销售商或制造商应适当建议最小化密封垫变形的可能性，尤其是在高温线上进行高温密封的球阀，并进行检查。
When the ball valve must always frequently switch in high speed fluid condition, vendors or manufacturers should suggest to minimize the possibility of Gasket deformationappropriately, especially the ball valves in the high- temperature line for high-temperature sealing, and check.g.节流装置：Throttling device当用阀门做为节流装置时，流体和钢球的前边缘能损坏密封垫的回弹力，导致泄露。
因此建议球阀一般不要用做节流。
用做节流时产生的高流体流速及悬浮固体颗粒将进一步缩短密封垫的使用寿命。
When the valves used as the throttle device, fluid and the front edge of the ball candamage the resiliency of the gasket, causing leakage. So, we suggest that ball valvegenerally don't used as throttle. High fluid velocity used for throttling and suspended solids will further shorten the service life of the seal.h.当打开阀门困难时，（阀体内正承受压力时）不要拧开螺帽检查。
用户可以通过管道系统用其它方法检查。
球阀不配备增压装置。
When you have difficulty opening the valve, (the body is under pressure) don't twist off the nut for inspection. Users can check in other ways through the piping system. Ball valve is not equipped with a supercharger device.南京苯邦阀门公司i.阀门处于高温时不要用手触摸其外表面。
Don't touch the outside surface when the valve is in high temperature.j.不允许应用于不稳定流体，除非在说明及使用手册中提及。
Unless mentioned in the description and user manual, applied to unstable fluid is notallowed.k.阀门手柄挂锁，是为了防止对阀门的误操作。
The valve handle hanging lock is to prevent wrong operation of the valve.2．产品介绍Product Introductiona. 标准类型,三片式全流量球阀.a. The standard type, three-pieces full-flow ball valve.b. 中轴倒装防脱出；防爆设计b.
