High-Performance Plug Valves for Shut-Off Applications
Product Description
Vcore Plug Valve is a quarter-turn rotary valve designed to provide reliable, bubble-tight shutoff in high-temperature and high-pressure environments. Manufactured with precision and long-term durability in mind, the plug valve is ideal for applications requiring infrequent operation with fast shutoff capabilities. The streamlined design minimizes flow resistance, while the full-port option ensures maximum throughput with minimal pressure drop.
Constructed from high-quality materials such as stainless steel, alloy steel, or ductile iron, this valve type is suitable for handling aggressive media including steam, oil, gas, and corrosive chemicals. The valve’s simple structure ensures ease of maintenance, with a smooth plug rotation ensuring consistent sealing performance even in demanding operating conditions.
