Product Technical Data Sheet

ASTM B148 C95800 Nickel Aluminum Bronze Angle Globe Valve

1. Product Overview

This product is an Angle Pattern Globe Valve constructed from ASTM B148 C95800 Nickel Aluminum Bronze casting alloy. C95800 is a high-strength copper casting alloy containing aluminum (8.5–9.5%), nickel (4.0–5.0%), and iron (3.5–4.5%), offering exceptional seawater corrosion resistance, cavitation resistance, and erosion-corrosion resistance.

The angle globe valve is a variation of the straight globe valve, featuring a 90-degree flow path that directs the flow at a right angle. This design provides three essential functions in a single component: shut-off the line, regulate flow, and change piping direction. Compared to a standard globe valve installed together with an external 90° elbow, the angle pattern integrates the turn inside the valve body, simplifying piping layout, reducing external joints, and improving suitability for high-pressure and space-constrained applications.

C95800 nickel aluminum bronze is recognized as having outstanding wear resistance—rated as the best of all bronzes—along with excellent corrosion resistance, making it an ideal material for marine hardware, pump and valve components handling seawater, sour mine waters, non-oxidizing acids, and industrial process fluids.

2. Angle Globe Valve Design Description

Angle Pattern (90-Degree Flow Path) : The inlet and outlet ports are oriented at 90° to each other, enabling the valve to simultaneously change fluid direction while providing throttling and isolation functions. This configuration offers:

Reduced Pressure Drop: The angled flow path provides a smoother flow transition, generating less pressure drop compared to straight globe valves with external elbows
Reduced Installed Complexity: Integrates the 90° turn inside the valve body, eliminating the need for separate pipe fittings
Reduced Leakage Risk: Every external joint eliminated reduces potential leak paths, which is critical for steam, hot oil, ammonia, and other demanding services
Space Efficiency: Facilitates compact piping layouts in skids, process modules, and confined installation spaces
Lower Erosion Potential: The 90° flow turn reduces direct impingement on seating surfaces compared to T-pattern globe valves
External Screw & Yoke (OS&Y) / Rising Stem Design: The stem threads are located outside the fluid chamber, protecting them from corrosion and providing visual indication of valve position. The stem rises when the valve is opened and lowers when closed.
