Copeland BVL系列内衬节流阀和控制阀
美国Copeland  BVL系列：内衬节流阀和控制阀
一些高压和/或研磨服务需要耐磨衬里来延长球阀的使用寿命并防止压力容器的腐蚀。杜邦公司为二氧化钛服务制造了二十多年前的*道阀门。这些阀门现在仍在使用，是我们为客户提供自主创新解决方案的一个例子。
用于E.I.DuPont的二氧化钛阀
内衬严重的服务科普兰球阀二氧化钛颗粒可以是锋利，坚硬，非常具有磨蚀性。工作温度通常约为1200°F（650°C）。高速气体推动这些颗粒，合金60需要满足身体的腐蚀要求。谷轮提供定期阀门的衬垫，其控制阀门线由各种材料（包括陶瓷）制成，以防止磨损。纳入内胆后，这些阀门的使用寿命延长了600％以上。
Copeland衬里控制阀用于高速磨料
控制阀在高温，高速，磨蚀，腐蚀和粉末/矿石运输的恶劣工况下可能需要对阀壁进行额外保护，以防止由于湍流或颗粒撞击而造成的磨损。陶瓷衬里，碳化物或其他材料可以提供更长使用寿命的需求。谷轮阀门采用重型超大型组件，可提高可靠性并防止意外停机。

BVL Series: Lined Throttling & Control Valves

Some high pressure and/or abrasive services require an abrasion resistant liner to extend the life of the ball valve and to prevent erosion of the pressure containing body. Copeland manufactured it's first line valves over 20 years ago for E. I. DuPont for titanium dioxide service. These valves are still in service today and are an example of the innovative solutions we pride ourselves in providing for our customers.

• Titanium Dioxide Valve for E. I. DuPont

  Titanium Dioxide particles can be sharp, hard and very abrasive. Service temperatures are normally approximay 1200 F (650 C). High velocity gas propels these particles and Alloy 60 is required to meet the corrosion demands of the body. Copeland provides liner for regular valves and its control valve line made of a variety materials including ceramic to prevent wear. Life of these valves after inclusion of the liner was extended by over 600%.

• Copeland Lined Control Valve For High Velocity Abrasives

  Control Valves in the severe service conditions of high temperature, high velocities, abrasives, corrosives and powder/ore transport may require additional protection to the walls of the valve to prevent wear due to turbulance or particle impingement. Liners of ceramics, carbides or other materials can provide an answer to a need for longer service life. Copeland valves utilize heavy duty, oversized components that increase reliability and prevent unplanned outages.
