Engineered for reliability in extreme conditions, our stainless steel valve bonnet is precision-crafted using investment casting technology to ensure leak-proof performance, corrosion resistance, and durability in critical valve systems. Designed for oil & gas, chemical processing, marine, and power generation industries, this valve bonnet guarantees seamless integration, high-pressure integrity, and long-term functionality. As a leading investment casting foundry, we deliver ISO-certified, customizable solutions that meet global engineering standards.
Corrosion Resistance: Made from grade 304/316 stainless steel for resilience against seawater, acids, and harsh chemicals.
Precision Engineering: Tight tolerances (±0.15mm) ensure perfect sealing surfaces and compatibility with valve bodies.
High-Pressure Durability: Withstands pressures up to 2500 PSI (ASME Class 150–2500) without deformation.
Customizable Designs: Adjustable flange types (RF, RTJ), stem bores, and threaded connections.
Extended Lifespan: Robust construction reduces maintenance costs and downtime.
