Design and Manufacturing Standards

The Marine U Section Double Flange Butterfly Valve is designed and manufactured following API 609 guidelines, ensuring consistency and performance. The face-to-face (F to F) dimensions align with ASME B16.10 and BS EN 558, allowing for seamless integration with existing systems. The valve's anti-blow out stem design prevents unintended disengagement under high-pressure conditions, enhancing safety and operational reliability.

Material Selection and Durability

The choice of materials plays a crucial role in the valve's performance. Ductile iron and stainless steel bodies provide exceptional strength and resistance to corrosion, while aluminum bronze discs offer excellent wear resistance. The Monel K-500 stem and VITON seats ensure longevity in aggressive environments. These materials are selected to meet the rigorous demands of marine and industrial applications, as outlined in ASTM and ISO standards.

Quality Control and Testing

SAVVY VALVES adheres to a rigorous quality control process, including:

• Chemical and Mechanical Analysis: 100% testing of raw materials for each heat number.
• Non-Destructive Testing (NDT): 100% DPT for castings, with optional MT (Magnetic Particle), UT (Ultrasonic), or RT (Radiographic) testing.
• Hydraulic and Air Testing: 100% hydraulic testing of the shell and seal, along with low-pressure air tests to ensure leak-tight performance.

These measures guarantee that every valve meets the highest industry standards, as verified by API 598 and API 6D protocols.
