ReflowX SKU: REF-0148
The JH Check Valve is a robust swing-type valve engineered for preventing backflow in high-pressure pipeline systems. Available in sizes from 2 inches to 48 inches (DN50 to DN1200) and pressure classes CL150 to CL2500 (PN16 to PN420), it complies with international standards such as API 6D, ASME B16.34, API 594, BS 1868, and GB/T 12236. The valve utilizes an internal rocker arm swing mechanism that eliminates external leakage paths, ensuring zero leakage performance. Its streamlined flow channel reduces pressure drop, while the valve disc is designed with micro-position compensation to enhance sealing accuracy and durability. Ideal for critical applications in oil & gas, petrochemical, and power systems, the JH swing check valve guarantees high reliability and long service life.
