10'' 600# WCC Long-Distance Pipeline API 6D Standard Cast Steel Piston-Type Check Valve

10'' 600# WCC Long-Distance Pipeline API 6D Standard Cast Steel Piston-Type Check Valve

The piston-type cushioned check valve utilizes a piston‑guided mechanism to open and close. When the medium flows in the forward direction, it lifts the piston to allow passage; when flow reverses, the medium pressure combined with the cushioning damping device ensures a slow, controlled closure, thereby preventing water hammer–induced damage to pipelines and equipment. The valve incorporates an integral cushioning oil cylinder assembly, enabling adjustable cushioning stroke and controllable closing speed. Its sealing pair is precisely matched, providing tight shut‑off and excellent bidirectional pressure‑resistant sealing. With a smooth flow path and low flow resistance, the valve is available in carbon steel, stainless steel, and other materials, offering superior resistance to high temperature and high pressure. It is widely used at pump outlets, as well as in heating, petrochemical, and water supply and drainage systems, effectively mitigating pump‑stop water hammer and ensuring the safe operation of pipeline networks.
