• Design: ASME B16.5 ball valves feature a floating ball with a resilient seat, providing bidirectional sealing.
• Sealing Mechanism: The resilient seat compresses against the ball, ensuring minimal leakage and reliable sealing.
• Materials: Typically made from carbon steel, stainless steel, or alloy steels.
• Testing: Undergo rigorous hydrostatic and pneumatic tests to ensure compliance with sealing standards.
• High-Pressure Applications: Suitable for high-pressure, high-flow environments.
• Quick Shutoff: Ideal for applications requiring rapid flow isolation.
• Corrosion Resistance: Stainless steel options make them suitable for corrosive fluids.
• Design: GB/T 9113 gate valves use a wedge-shaped gate for unidirectional sealing.
• Sealing Mechanism: The gate compresses against the seat, providing excellent tight shutoff.
• Materials: Available in cast iron, carbon steel, stainless steel, or alloy steels.
• Testing: Tested according to GB/T standards to ensure minimal leakage.
• Tight Shutoff: Ideal for applications requiring minimal leakage.
• On-Off Control: Suitable for applications where flow needs to be fully stopped or started.
• Versatility: Available in various sizes and materials for different industrial needs.
