Frequently Ask Questions
Yes, ALIS Valves is a Piston Type Flow Regulator Manufacturer in India, offering flow-control solutions for water, pumping, water treatment and industrial pipeline applications.
Yes, some designs can be configured with electric control for remote or automated flow regulation.
The piston provides controlled movement of the flow passage, allowing stable regulation over a wide operating range.
Yes. Piston flow regulators are particularly suited to large pipeline sizes, with published designs extending to DN2000.
A high pressure reduction ratio can create high velocity and pressure-drop conditions, so valve sizing and anti-cavitation design are important.
Differential pressure affects the hydraulic forces acting on the piston and must be considered when sizing the valve and actuator.
Cavitation can occur when local pressure falls sufficiently during pressure reduction. Proper sizing and staged pressure reduction can help control this condition.
Required information normally includes pipe size, flow rate, inlet pressure, outlet pressure, medium, temperature and required control conditions.
