2500LB Swing Check Valve

Swing check valve is suitable for water, steam, oil, gas and weak corrosive media, widely used in petroleum, chemical, electric power, metallurgy and other industries in low and medium pressure piping system. The valve uses the valve flap to rotate around the axis of opening and closing, low resistance, suitable for large flow, low-frequency opening and closing conditions. The working temperature range is generally -29℃ to +550℃, depending on the material. The main function is to prevent backflow of media and protect equipment safety. Commonly used materials include carbon steel, stainless steel, alloy steel, sealing surface can be stainless steel or carbide, with good sealing and durability.

Product Overview	The 2500LB Swing Check Valve is an ultra-high pressure, heavy-duty valve designed for the most demanding industrial applications. Rated to Class 2500 (ASME B16.34), the valve can withstand extremely high pressures (up to 420 bar/6,090 psi) and high temperatures (up to 800°F/427°C), making it ideal for critical applications in the oil and gas, petrochemical, and power generation industries. Constructed from forged steel (carbon or alloy steel), this valve offers superior strength and durability to ensure reliable performance in ultra-high pressure systems. Its swing-open flap design ensures minimal pressure drop and immediate sealing in the event of reverse flow, while its rugged construction provides long term reliable performance in harsh operating conditions.

Main features	Ultrahigh-Pressure Rating: Designed to Class 2500 (ASME B16.34) for pressures up to 420 bar (6,090 psi). High-temperature performance: Reliable operation in temperatures up to 800°F (427°C), with options for higher temperature materials. Forged steel construction: Valve body material: forged carbon steel (ASTM A105) or forged alloy steel (ASTM A182 F22/F91). Superior strength and resistance to deformation under extreme pressure. Oscillating Flap Design: Hinged flaps allow smooth, low-resistance fluid flow in the downstream direction and seal immediately upon fluid reversal. Effectively reduces the water strike effect compared to other types of check valves. Compliance: Meets API 594, ASME B16.34, and NACE MR0175 for ultra-high pressure and sour service applications.

Product Advantages	Superior Strength: Forged steel construction ensures reliability under extreme pressure. High temperature resistance: suitable for steam and other high temperature media. Low maintenance: Self-cleaning valve design reduces wear and prolongs service life. Versatility: Suitable for horizontal or vertical installation. Global Compliance: Meets API, ASME and NACE international program standards.
