Check Valve Manufacturers

          AVLOK® is recognized as one of the leading check valve manufacturers, delivering high-performance solutions tailored to the requirements of multiple industries, including oil & gas, petrochemicals, chemicals, pharmaceuticals, water treatment, power plants, and instrumentation systems. Our valves are designed with accuracy, reliability, and durability in mind, ensuring smooth operation even in challenging industrial environments.

          We specialize in a wide selection of check valves, such as brass check valves, stainless steel check valves, relief valves, non-return valves, and ball check valves. Each product is built to withstand high-pressure and temperature conditions, making them suitable for both liquid and gas applications. AVLOK®’s instrument check valves are specifically engineered to maintain unidirectional flow, ensuring that media moves in a single direction while preventing any reverse flow. These valves provide a tight shut-off and safe performance, automatically closing when differential pressure falls below the preset cracking pressure of 20 psi ±30%.

          In cases where leak-tight shut-off is not the main requirement, ball check valves offer an effective solution. They are widely used in pneumatic and hydraulic systems, chemical pipelines, and fluid handling applications, as they automatically close once the differential pressure drops below the cracking value. Their rugged and low-maintenance design makes them ideal for continuous and long-term use.
