Cast Steel Gate Valve

Chaoda’s Cast Steel OS&Y Gate Valves are designed for high-performance critical flow control applications. These valves feature a straight-through, bi-directional flow path that minimizes flow loss and pressure drop, making them ideal for systems where efficiency and reliability are paramount. The flex wedge design ensures consistent sealing even under thermal expansion and pipeline stress, while the standard low-emissions graphite packing and backseat design provide enhanced safety and compliance with environmental regulations. With proven performance in oil/gas refining, chemical processing, power generation, and pulp & paper industries, Chaoda gate valves deliver long-term durability, operational safety, and regulatory compliance in the most demanding environments.
