Stellite Valve Balls And Valve Seats

Description of Stellite Valve Balls and Valve Seats

Stellite alloy has four fundamental use cases - coating, molding, internal sleeve, and manufacturing for industrial valves, positioning its ball and seat valve assemblies as the valve's apex boundary for fluid flow regulation. Stellite Alloy for ball and seat assembly products is not cobalt, precision cast, or powder metallurgically cast. Moreover, Stellite cobalt alloy contains cobalt, pricey cobalt. chromium, and tungsten. Stellite cobalt chromium tungsten alloy is said to have unrivaled facility operational prowess.

Operationally, the Stellite Valve Balls and Valve Seats must rotate, raise, and lower the ball, the moving part, for precise alignment. To open, close, and regulate flow, the Stellite Valve Balls and Valve Seats must separate to open and close, with the two contact surfaces for precise alignment opposing surfaces. Rotating the ball valve must undergo mechanical friction, high-speed fluid impact, and eroding fine particles during the control of close regulation of flow. Featuring high internal hardness, tough alloy, and excellent wear resistance, Stellite wear and fluid leakage have an immense capacity to control breakdown, and while fluid leakage in perpetuity will not.

Additionally, this part demonstrates excellent versatility. Be it elevated temperatures and pressures of superheated steam, corrosive chemicals, and beyond, Stellite Alloy performs consistently and is resistant to softening, corrosion, and deformation, thus guaranteeing sealing for valves lasting under extreme and varied conditions, as well as a long service life. Stroking corrosion-resistant valves is extreme. The extreme range of processes like alloy smelting and fine grinding is controlled to guarantee the valve ball and valve seat taper fit perfectly with the least possible error.

Features of Stellite Valve Balls and Valve Seats

• Ultra-hard and wear-resistant: The weld overlay possesses a hardness of 38-50 HRC and is strengthened with carbide dispersion, giving it a usable life 3-5 times longer than 316L at a temperature with suspended solid particulates.

• High-temperature resistance: Endures a strength-sustaining long-term temperature of 800 degrees Celsius and oxidizes at 980 degrees Celsius in short durations.

• Corrosion resistance: The high-chromium + cobalt matrix is less prone to pitting than stainless steel in acidic, saline, and hydrogen sulfide waters.

• Zero-leakage metal seal: Wediing leaktight to a hardened spherical surface achieves leakage ratings of API 6A/FCI 70-2 Class V/VI.

• Impact fatigue resistance: Exceptional durability with no chipping or peeling after countless cycles of opening and closing.

Applications of Stellite Valve Balls and Valve Seats

• Oil and Gas: Stellite Valve Balls and Valve Seats sealing surfaces for high-pressure/sand-laden wellhead ball valves and long-distance pipeline emergency shut-off valves.

• Thermal and Nuclear Power: Sealing pairs for main steam isolation valves and feedwater recirculation valves, resistant to cavitation and radiation.

• Chemical: Core components of metal-sealed ball valves and plug valves for slurry, catalyst, and chlor-alkali media.

• Aerospace: Ball-seat assemblies for high-pressure ball valves in rocket fuel filling systems.
