Axial Nozzle Check Valves
Compact, non-slam axial nozzle check valve designed for low pressure loss, fast response, and fire-safe performance in critical industrial systems.
Surface Axial Nozzle Check Valves are advanced non-return valves engineered to prevent reverse flow and protect critical equipment in industrial process systems. Featuring a streamlined axial flow path and optimized ring/disc geometry, these valves deliver very low pressure loss, fast response, and smooth non-slam operation. Their compact design makes them ideal for space-constrained surface installations such as oil and gas platforms, LNG facilities, pump discharge lines, and antisurge systems.
Built according to major API and ISO standards, they are available in forged or cast bodies with hard-faced metal seating and fire-safe construction. They support a wide range of materials, temperature classes, pressure ratings, and end connections, with optional certifications including NACE, PED, ATEX, and high-level API QSL/PSL requirements.
