Alis Valves offers high-quality Swing Check Valves designed to prevent reverse flow in pipelines. The valve operates automatically using a hinged disc that swings open with forward flow and closes when flow stops or reverses. These valves are widely used in water, oil, gas, and process industries to protect pumps, compressors, and other equipment from backflow damage.

Frequently Ask Questions

A Swing Check Valve is an automatic non-return valve that allows fluid to flow in one direction and prevents it from flowing backward.
Its primary purpose is to prevent backflow and protect pumps, compressors, pipelines and other process equipment.
A Swing Check Valve uses one hinged disc, while a Dual Plate Check Valve uses two spring-assisted plates. Dual-plate designs generally provide a more compact construction and faster closing, while swing check valves offer a simple and robust construction.
During normal forward flow, fluid pressure pushes the disc away from its seat. When flow decreases, gravity and reverse-flow pressure cause the disc to swing back onto the seat, stopping reverse flow.
No. A conventional swing check valve is self-operating and does not require a pneumatic, electric or hydraulic actuator.
Alis Valves manufactures and supplies industrial check valves for water treatment, oil & gas, chemical, petrochemical, power generation, HVAC and general process applications, including swing check valve solutions.
