• Duplex Discharge Valves Duplex stainless steel is a steel which has half of ferrite phase and half of austenitic phase in its quenching structure,and generally the minimum phase content must be up to 30%.
• Super Austenitic Ball Valves Super Austenitic Ball Valves exhibit great resistance to chloride pitting and crevice corrosion because of high molybdenum content (>6%) and nitrogen additions.These steels approach the performance...
• Monel Gate Valves Monel® nickel-copper alloy 400 is a solid solution alloy that may be hardened only by cold working. It has high strength and toughness over a wide temperature range and excellent resistance to many ...
• Super Austenitic Butterfly Valves Super austenitic stainless steel corrosion resistance is higher than the duplex grades, because its alloy content is higher. It has a high PREN(pitting resistance equivalency number) for superior resi...
• Super Austenitic Plug Valves Super Austenitic stainless steel combines with 904L, 254SMO, AL-6XN, Alloy 20 etc.
• Super Austenitic Globe Valves Common super austenitic stainless steels used in the valve industry are UNS S31254 (254SMO and AL6XN). They are predominantly used to obtain both higher strength and improved resistance to crevice cor...
• Super Austenitic Check Valves Super austenitic steels are amagnetic and present good weldability and excellent formability.Highly alloyed iron-nickel-chromium stainless steels containing molybdenum have been developed to respond t...
• NAB C95800 Ball Valves Nickel Aluminum Bronze Ball Valves of Weidouli own excellent corrosion resistance, being a suitable and far cheaper substitute to monel for many seawater applications. Nickel Aluminum Bronze ball valv...
• Hastelloy Gate Valves Hastelloy contains ultra-low carbon and high Ni, Mo and Cr elements, which belongs to corrosion-resistant and high temperature-resistant materials. Our product has been applied in the severe industri...
• NAB C95800 Butterfly Valves Nickel Aluminium-bronze valves are suitable for many sea water applications, especially in low pressure applications. The most common valve in NAB is the large butterfly valves which offer come with a...
• NAB C95800 Globe Valves Aluminum-bronze valves are a suitable and far cheaper substitute to duplex, super duplex, and monel for many seawater applications, especially in low-pressure applications. Its major drawback is its l...
• NAB C95800 Check Valves Alloys of copper and aluminium are known as aluminium bronze and, together with other alloying additions, produce a range of properties that are beneficial to a diverse range of industries. Of these, ...
• Super Austenitic Discharge Valves Stainless steel with high nickel, high molybdenum, copper, and nitrogen, and the microstructure of matrix metal is typical of 100% Austenite is called Super Austenite stainless steel.Because super aus...
• Stainless Steel Ball Valves Stainless steel Ball Valves of Weidouli can withstand ultra-high pressure and ultra-high temperature, being widely used to control the flow of fluids such as air, water, steam, corrosive medium, mud, ...
• Inconel Gate Valves Inconel has many different grades, such asInconel600,Inconel625 and Incoloy 800H. Different grades have different corrosion resistance, being able to meet various industrial applications. Valves have ...
