Check Valve

Reliable Non-Return Valves for Backflow Prevention

Check valves are automatic one-way valves that allow fluid to flow in only one direction while preventing reverse flow. They operate passively using differential pressure, opening with forward flow and closing tightly when flow stops or reverses. Anante's check valves ensure system protection, reduce water hammer, and maintain process integrity across diverse applications. Available in swing, dual-plate, lift, and piston designs, they offer low pressure drop, silent operation, and minimal maintenance. Suitable for oil & gas, water treatment, chemical, and power systems, these valves provide dependable performance with metal or soft seating, fire-safe options, and compliance with API, ASME, and ISO standards.

Swing Check Valve

Reliable Backflow Prevention with Swing Check Valves

Swing check valves, also known as backflow preventers, allow fluid to flow in only one direction while automatically preventing reverse flow. The valve features a hinged disc that swings open with forward flow and closes against the seat to block backflow. Ideal for various industries, swing check valves offer low-pressure drop, affordability, and ease of installation, making them suitable for water, wastewater, and general fluid control applications.
