Frequently Ask Questions
A Ball Check Valve is a non-return valve that uses a ball as the closing element to automatically prevent reverse flow.
Common options include EPDM, NBR and PTFE, selected according to the medium, temperature and chemical compatibility.
Its performance depends on the ball weight, flow velocity and closing characteristics. For applications specifically requiring controlled closure, a slow-closing check valve may be considered.
Yes, when correctly sized for the pump flow, pressure, backflow conditions and required closing characteristics.
Forward flow moves the ball away from the seat. When flow stops or reverses, the ball returns to the seat and prevents backflow.
Differential pressure affects ball movement, sealing force and pressure loss, so the valve should be selected according to actual operating conditions.
PTFE may be selected where chemical compatibility and temperature requirements exceed the practical range of common elastomer seats.
Yes, ALIS Valves is a Ball Check Valve Manufacturer in India, offering check valve solutions for water, wastewater, chemical, pumping and industrial applications.
