1. Unmatched Corrosion Protection
With a chemical composition of 19.5-20.5% Cr, 6.0-7.0% Mo, copper and nitrogen, the valve achieves a PREN (Pitting Resistance Equivalent Number) over 40. This superior alloy formula ensures reliable operation in high-chloride media, seawater, dilute acids, alkaline solutions and flue gas desulfurization (FGD) slurries, eliminating costly downtime caused by valve failure.
2. Smooth Operation & Zero Leakage Seal
The precision-machined conical plug design ensures tight shut-off that meets API 6D zero leakage standards. Its streamlined full-bore flow path reduces pressure drop and energy consumption, while the low operating torque allows easy operation with manual, gear, pneumatic or electric actuators—perfect for both manual control and automated process systems.
3. Broad Temperature & Pressure Range
After undergoing solution heat treatment at 1100-1150°C (water quenched), the valve maintains a uniform austenitic structure that performs flawlessly from -40°C to 425°C. It supports pressure ratings from Class 150 to Class 600, adapting seamlessly to extreme temperature fluctuations and high-pressure working conditions without deformation or seal failure.
4. Compliance & Customization Options
Manufactured in strict accordance with API 6D and ASME B16.34 international standards, the valve is available with CE, API and ISO 9001 certifications to meet global market requirements. Customization services include flanged, welded or threaded connections, fire-safe/anti-static designs, and upgraded trim materials to fit your specific project needs.
