Copeland高周期浆料阀门
Slurriy阀门设计为高，低周期率。浆料密度，粒度和硬度，腐蚀性等诸多因素可能会有很大差异。谷轮拥有所有这些球阀。看下面的一些例子。
更换TFE或氟橡胶座椅
Copeland硬质合金系列阀门，适用于磨料浆的高周期应用Corbetland BVC系列高性价比的高循环阀，采用不锈钢金属阀座，并配有谷轮公司内部应用的HVOF和等离子涂层线。这些涂料已经被广泛接受，因为它们成功地防止了二氧化硅（砂）应用，过热蒸汽和酸应用中的磨损和腐蚀。球被允许在座位之间“浮动”，但是当材料进入体腔并被包装在内部时，球仅有千分之一英寸防止阀门锁定。
铬镍铁合金重型泥浆阀
带花键的加长轴的镍铬铁合金阀门锻造体;坚硬，耐磨的覆盖层;一个花键轴和铬镍铁合金部件帮助这个阀门延长了它的寿命，远远超出了预期的使用寿命。经过10多年磨料浆和浓浆的高周期服务，现在是时候进行翻新了。翻新工作在不到一个星期的时间里完成了。
三件式衬里阀门
带衬里的BV Sereis球阀三件式锻造件，带有碳化钨，铬化合物或其他研磨材料的特殊衬里，可用于高速流动和在线可修复的解决方案。

救济削减选项
Copeland BV和PV系列经常被选择用于涉及高速颗粒物流的高温高循环操作。缓解切口可以被纳入设计，以更快速地释放压力，并避免硬金属颗粒损坏球的前缘。请参阅我们的视频进行完整的演示。
泥浆阀通常涉及的不仅仅是防止磨粒流。酸，腐蚀剂，压力和温度，高循环速率和胶质或细颗粒都可以起到浆料阀功能良好的作用。

Copeland High Cycle Slurry Valves

Slurriy valves are designed for both high and low cycle rates. Slurries may vary a great deal in density, particle size and hardness, corrosiveness and many other factors. Copeland has ball valves for all of these. See some of the examples below.

• Replacement of TFE or Viton Seats

  Copeland's BVC Series, high cycle valves that are cost effective but utilize stainless metal seats overlayed with Copeland's in-house applied line of HVOF and Plasma overlays. These coatings have gained wide acceptance because of their success in preventing wear and errosion in silica (sand) applications, superheated steam and acid applications. The ball is allowed to "float" between the seats but only a few thousandths of an inch protecting the valve against lock-ups when materials enter the body cavity and become packed inside.

• Inconel Heavy Slurry Valve

  A forged body; hard, wear resistant overlays; a splined shaft and Inconel components helped this valve extend it's life far beyond its expected life when first installed. After 10 years of high cycle service in abrasive and thick slurries it was time to be refurbished. Refurbishment was accomplished in  less than a week.

• Three Piece Lined Valves

  Three piece, forged bodies with special liners of tungsten carbide, chromide or other abrasive materials are available for high velocity flow and in-line repairable solutions.

Copeland's Pressure Relief Cut Option 

The Relief Cut Option

Copeland BV and PV Series are often selected for high temperature, high cycle operations involving high velocity particulate flow. The Relief Cut may be incorporated into the design to relieve pressure more quickly and to avoid damage by hard metal particles to the leading edge of the ball. See our video for a full presentation.

Have Questions?

Slurry valves often involve more than just protection against an abrasive particle stream. Acids, caustics, extreme pressures and temperatures, hich cycle rates and gummy or fine particles can all play a part in how well a slurry valve functions.
