陸功工業 Zipson valve 不但能提供常見的金屬材質，如 ASME (美規) 標準中的 CF8M, WCB, CF8, CF3M，EN (歐規) 標準中的 1.4408, 1.4308, 1.0619 以及JIS (日規) 標準中的 SCS14, SCS13, SCS16。也能為您的特殊需求，提供特殊合金球閥。不論您需要的是特殊材質的球閥或是精密鑄件，陸功都能依照您的設計和需求提供相應的產品。
陸功主要提供並庫存的特殊合金球閥為兩片式法蘭球閥 207F、三片式 2000 psi 高壓球閥 305D以及三片式 1000 psi 標準球閥 302F。此外，上通式110F/ 110T，和三通法蘭球閥501F，也有一些特殊合金鑄件庫存。這些可立即組裝的閥門鑄件，能幫助我們的客戶解決緊急的需求，讓球閥提早上線使用。
陸功庫存的特殊合金材質大多為雙向鋼系列，如 CE3MN 超級雙相鋼閥 (超級雙向鋼, 5A, 2507), CD3MN 雙相鋼閥 (雙向鋼, 4A, 2205)。為了滿足客戶海水淡化廠及設備的需求，我們也庫存鎳基合金材質 CW12MW Hastelloy C 閥 (Hastelloy C), CX2MW (Hastelloy C-22), CN7M Alloy 20 閥 (Alloy 20), Monel (M35-1) 以及 CK3MCuN (254 SMO)。此外，我們也能為高腐蝕性流體等特殊工況，提供 ASTM G2等級的鈦合金球閥。
超級雙向鋼球閥 (A890 Gr.5A)常用於海水處理廠，海水淡化廠和礦業設備。此超級雙相鋼 CE3MN (5A) 球閥，亦常見於棕櫚油精煉廠。哈氏合金 C276則常被用於處理含氯化物或含氯流體。雙向鋼及超級雙向鋼，是海水淡化廠最常選用的球閥材質。哈式合金 Hastelloy C-22(CX2MW) 則常用於製藥業。
如果客戶有需求，陸功 Zipson 精密鑄造廠也相當樂意協助客戶，依照客戶提供的圖檔及檢驗要求提供球閥以外的特殊合金鑄件。
有些特殊的製藥設備，需要用肥粒鐵含量特別低的材質製作(≦3% or ≦1%)。對於有這類需求的製藥業者，陸功能提供肥粒鐵含量低於 1%的鑄件，每一爐生產時，皆會用肥力鐵含量檢測儀進行檢驗。
要是客戶需要對所購買的特殊合金產品進行測試，陸功能協助聯繫第三方認證團隊，針對客人需要的項目進行認證測驗，確保這些產品符合規範。我們能協助進行的測驗包含如下：
金屬材料腐蝕試驗(ASTM G48)：以4×4公分或10×10公分的試片，進行72小時或24小時的耐腐蝕測驗。
陸功 Zipson 庫存了大部份的特殊合金鑄件及零件，供客戶在最短時間內提取。一般而言，有鑄件的特殊合金閥可在下單後 25 日內出貨，若無零件庫存則需 70-80 日的生產時程。

* Test by Ferric Chloride Pitting Test for ZIPSON’ CE3MN (ASTM G48 Practice A)
* In the ASTM G48 Method A test, ZIPSON do the most critical condition at 50 deg. C for 72 hours.
The wonderful corrosion resistance alloy. Hastelloy C valve has excellent ability to resist strong oxidizers such as ferric and cupric chlorides, chlorine. The material is also a good choice for most of the corrosive problem.
Hastelloy C-22 is very similar to Hastelloy C-276, some called New Hastelloy C. This material was popular in pharmaceutical industries and in chemical processing, pollution control, waste water, etc. Hastelloy C-22 is better than C-276 when used in saturated wet Chlorine condition.
Alloy 20 is very popular used in sulfuric acid & aerospace cryogenic fuel tanks with low density and exhibits high strength.
The nickel content alloy with high strength with excellent corrosion resistance for media including sea water, sulfuric acid, alkali media.
254 SMO (1.4547/ UNS S31254/ A182 F44), is designed to resistance to pitting and crevice corrosion. And offers Chloride resistance superior to that of Alloy 904L, Alloy 20, Alloy 825. 254 SMO valve is very popular used in desalination skid or equipment.
Titanium (ASTM Grade 2) is light, and with excellent corrosion resistance in highly oxidizing to mildly reducing environment, including Chlorides. Ti has good impact properties at low temperature, it can be used at both cold and hot works.
Alloy 625 is one of Nickel-Chromium-Molybdenum alloy. It is with high strength and excellent wide range of corrosive resistance, especially to pitting and crevice corrosion.
Alloy 59 is one type of Nickel-Chromium-Molybdenum alloy. It is noted for the resistance of wide range of corrosive media and environments, both for oxidizing and reducing.
