2500LB swing check valve
2500LB swing check valve
Product Overview | The 2500LB Swing Check Valve is an ultra-high-pressure, heavy-duty valve designed for the most demanding industrial applications. Rated for Class 2500 (ASME B16.34), this valve is engineered to withstand extreme pressures (up to 420 bar/6,090 psi) and high temperatures (up to 800°F/427°C), making it ideal for critical applications in oil & gas, petrochemical, and power generation industries. Constructed from forged steel (carbon steel or alloy steel), this valve offers exceptional strength and durability, ensuring reliable performance in ultra-high-pressure systems. Its swing disc design ensures minimal pressure drop and immediate sealing upon flow reversal, while its robust construction provides long-term reliability in harsh operating conditions. |
Key Features | Ultra-High Pressure Rating:Designed for Class 2500 (ASME B16.34), suitable for pressures up to 420 bar (6,090 psi). High-Temperature Capability:Operates reliably in temperatures up to 800°F (427°C), with optional materials for even higher temperatures. Forged Steel Construction:Body materials: Forged carbon steel (ASTM A105) or forged alloy steel (ASTM A182 F22/F91).Provides superior strength and resistance to deformation under extreme pressures. Swing Disc Design:Hinged disc allows smooth, low-resistance flow in the forward direction and immediate sealing upon flow reversal.Reduces water hammer effects compared to other check valve types. Compliance:Meets API 594, ASME B16.34, and NACE MR0175 standards for ultra-high-pressure and sour service applications. |
Operational Advantages | Exceptional Strength: Forged steel construction ensures reliability under extreme pressures. High-Temperature Performance: Suitable for steam and other high-temperature media. Low Maintenance: Self-cleaning disc design reduces wear and extends service life. Versatility: Suitable for horizontal or vertical installation. Global Compliance: Meets API, ASME, and NACE standards for international projects. |
