Copeland漿料閥門，Copeland合金重型泥漿閥
Copeland高周期漿料閥門
Slurriy閥門設計為高，低周期率。漿料密度，粒度和硬度，腐蝕性等諸多因素可能會有很大差異。谷輪擁有所有這些球閥。看下面的一些例子。
更換TFE或氟橡膠座椅
Copeland硬質合金系列閥門，適用于磨料漿的高周期應用Corbetland BVC系列高性價比的高循環閥，采用不銹鋼金屬閥座，并配有谷輪公司內部應用的HVOF和等離子涂層線。這些涂料已經被廣泛接受，因為它們成功地防止了二氧化硅（砂）應用，過熱蒸汽和酸應用中的磨損和腐蝕。球被允許在座位之間“浮動”，但是當材料進入體腔并被包裝在內部時，球僅有千分之一英寸防止閥門鎖定。
鉻鎳鐵合金重型泥漿閥
帶花鍵的加長軸的鎳鉻鐵合金閥門鍛造體;堅硬，耐磨的覆蓋層;一個花鍵軸和鉻鎳鐵合金部件幫助這個閥門延長了它的壽命，遠遠超出了預期的使用壽命。經過10多年磨料漿和濃漿的高周期服務，現在是時候進行翻新了。翻新工作在不到一個星期的時間里完成了。
三件式襯里閥門
帶襯里的BV Sereis球閥三件式鍛造件，帶有碳化鎢，鉻化合物或其他研磨材料的特殊襯里，可用于高速流動和在線可修復的解決方案。

Copeland BV和PV系列經常被選擇用于涉及高速顆粒物流的高溫高循環操作。緩解切口可以被納入設計，以更快速地釋放壓力，并避免硬金屬顆粒損壞球的前緣。請參閱我們的視頻進行完整的演示。
泥漿閥通常涉及的不僅僅是防止磨粒流。酸，腐蝕劑，壓力和溫度，高循環速率和膠質或細顆粒都可以起到漿料閥功能良好的作用。
Copeland漿料閥門，Copeland合金重型泥漿閥
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.
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.
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, 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 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.
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.
