V-ring seal

spring-energizedmetalfor high-temperature applications

Gas & steam turbines • Valves • Swivels • Turbochargers Metal V-ring is based on a metallic "V" substrate, designed to be applied in extreme working conditions. Metal V-Rings for internal Pressure or external Pressure are system pressure energized, they require low bolting load and have good spring back. Due to its special structure and material, Metal V-rings can be used in working conditions such as high temperature, cryogenic , high pressure (up to 1500kgf/cm2), high vacuum (up to 1E-9 mmHg) and other extreme working conditions of static sealing. Sonkit Metal V-Ring are designed to combine the advantages of compactness, lowest leakage rates, high pressure capability, and high springback. Operating Conditions: 01 Work pressure range: .Vacuum (1E-torr) 02 Temperature range: 03 Typical leakage rate: 1E-10 sccs He/mm circ. 04 Metallic Material Options: • Alloy 718 • Alloy X-750 • 316 SS • 321 SS • Waspaloy 05 Plating/Coating Options: • Silver • Nickel • Gold • Stannum • Copper • PTFE Application Characteristics 1. Metal V-Ring are designed to combine the advantages of compactness, lowest leakage rates, high pressure capability, and high springback. 2.Good sealing performance with : • High temperature resistance • High pressure resistance • Wear resistance • Corrosion resistance
