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 low tolerance to heat. Aluminium-bronze is also referred to as nickel-aluminum bronze and abbreviated as NAB. C95800 offers superior saltwater corrosion resistance. It also is resistant to cavitation and erosion. Along with the advantage of pressure tightness, this high-strength alloy is excellent for welding and is available in many forms at a lower cost to you. So NAB C95800 Globe valves are typically used for shipbuilding with seawater or fire water application. The Fact That NAB C95800 Globe Valves cost-effective (cheaper than the exotic alternatives); long-lasting (comparable in performance on general corrosion, pitting, and cavitation to super duplex alloys and significantly better than the standard alloys), and a good valve material (does not gall, has excellent anti-fouling properties, and is a good thermal conductor), makes it an excellent choice for valves in seawater service.

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 valves are mainly composed of nickel and ferromanganese. With excellent corrosion resistance, Nickel aluminium ball valve act as an important material for marine propellers, pumps, valves and underwater fasteners, being widely used in seawater desalination and petrochemical industry. ​ Why Use NAB Aluminum Ball Valve? The advantages of NAB nickel ball valve are significant. These types of industrial valve are particularly suitable for seawater service, where the corrosion properties, especially their resistance to chloride pitting, are excellent. The technology for producing castings of consistent quality is well known, and there is little need for the extensive non-destructive testing that is required for 6Mo, duplex, and super duplex steels. Mechanically, this hand ball valve is comparable to other popular corrosion- resistant alloys, but in order to take full advantage of these properties, specially defined pressure-temperature ratings must be used. Excellent occlusal and wear properties help to ensure the longevity and good performance of NAB ball valves. The limitations of this type of hand operated valve are that it should not be used in a sulphide environment and its flow limits must be considered. Competing cast iron and steel valves require some form of protection to compete and even then the quality and durability of this protection determines longevity. Stainless steel valves are subject to severe crevice corrosion and pitting in seawater, and 6Mo, duplex and super duplex stainless steel valves are limited to a temperature of 20 ℃ and a maximum chlorine content in seawater service. The cost of the more exotic higher alloys becomes a key factor and requires a special justification. Application of NAB C95800 Bronze Ball Valve Ocean engineering Petrochemical industry Coal chemical industry Pharmacy Pulp & Paper making industry Weidouli Valves Co., Ltd., is a professional valve manufacturing company, we provide valve for sale, hand operated valve, etc. Contact us to know valve price or more.
