A Check Valve, also known as a non-return valve or one-way valve, is a type of industrial valve that allows fluids to flow freely in one direction while preventing backflow to the opposite direction. It operates automatically without external control, closing when flow reverses and maintaining the proper direction of flow in a system.
Our check valves are appreciated for their automatic operation, backflow prevention, equipment protection, and ability to enhance system efficiency. We offer various types of check valves, including swing type, y-spring type, lift type, and wafer type check valves, which are connected to pipelines by either threaded or flanged connections, providing a leak-proof seal. These valves are available in a variety of pressure models, such as 800WOG, 150LB, 300LB, and 10K, and are mainly constructed from stainless steel 316 (ASTM A351 Gr CF8M) or carbon steel ASTM A216 Gr. WCB, providing excellent corrosion resistance, high tensile strength, and long-term durability.
