Frequently Ask Questions
A Dual Plate Check Valve is lighter, more compact, and closes faster than a swing check valve. Its spring-assisted design helps reduce water hammer and protects pumps and pipelines from reverse flow.
These valves are widely used in oil & gas, chemical plants, power generation, water treatment, marine systems, fire protection, HVAC, paper mills, and industrial process plants.
Alis Valves manufactures and supplies industrial check valves for water treatment, oil & gas, chemical, petrochemical, power generation and general process applications, including dual-plate check-valve solutions.
Yes. Most Dual Plate Check Valves can be installed in both horizontal and vertical pipelines, provided the flow direction matches the arrow marked on the valve body.
No. Since it operates automatically without external controls, maintenance requirements are minimal. Regular inspection during scheduled plant shutdowns is generally sufficient.
Its spring-assisted plates begin closing as the flow velocity decreases, helping minimize reverse-flow acceleration before complete closure.
