I. C95800 Nickel Aluminum Bronze Material: Core Choice for Marine Corrosive Service
C95800 Nickel Aluminum Bronze (NAB) is a premium casting material widely adopted for marine engineering and seawater piping systems. This 2" Class 150 top entry floating ball valve features a fully cast C95800 valve body. Compared with carbon steel and stainless steel alternatives, NAB delivers outstanding resistance to seawater erosion, pitting corrosion and marine organism fouling. In high-salinity coastal environments, it maintains long-term operation and effectively prevents rusting and medium leakage.
Offshore platforms, ship seawater pipelines and coastal chemical plants frequently select C95800 ball valves. Ordinary 304 or 316 stainless steel tends to suffer chloride-induced pitting when exposed to seawater over long periods, while the metallurgical structure of C95800 NAB withstands chloride attack, making it ideal for seawater transfer and brine circulation services.
II. Top Entry Floating Ball Valve Design for Simplified On-site Maintenance
This 2-inch Class150 top entry floating ball valve adopts a top entry structure. The internal ball and seat seals can be inspected and replaced in-line without removing the entire valve from the pipeline.
Floating ball design: medium pressure pushes the ball against seat faces for reliable sealing across low to rated pressure range.
Top entry construction: cuts downtime and eliminates heavy pipeline disassembly work during maintenance.
Class 150 pressure rating, suitable for low-pressure seawater and process water systems.
Flanged ends to ASME B16.5 standard for direct mating with standard pipe flanges.
The factory image shows neatly stacked semi-finished C95800 valve bodies after precision machining. Every valve body is CNC machined to tight tolerances on flange surface and valve cavity to guarantee sealing accuracy after assembly.
III. Standardized Manufacturing & Strict Quality Control at J-Valves
Since 2009, J-Valves has delivered integrated industrial valve solutions. NAB special alloy ball valves are one of our core product lines. We have established dedicated inspection procedures for copper alloy valves like C95800:
1. Raw material spectral analysis to verify C95800 chemical composition and avoid material substitution.
2. Casting NDT inspection to detect casting defects such as blowholes and sand inclusions.
3. CNC precision machining for flanges, valve cavities and seat pockets.
4. Hydrostatic and air leakage test on every assembled valve to confirm zero leakage.
5. Final cleaning and protective packaging to avoid seal surface damage during shipment.
For marine project clients, full documentation including material test certificates, NDT reports and pressure test certificates can be supplied to meet marine and offshore project approval requirements.
IV. Typical Application Fields
This 2" 150LB C95800 top entry floating ball valve is commonly used in:
Ship seawater main lines and cooling seawater systems
Offshore platforms, coastal power plant seawater circulation pipelines
Salt chemical industry and brine transfer process lines
Desalination and offshore water treatment facilities
