Valve
Valves are used to control, stop, regulate, or redirect the flow of water, gas, and other fluids in pipeline systems. They support safe operation, stable pressure control, and efficient fluid management.Common valve types include ball valves, gate valves, butterfly valves, check valves, and pressure control valves. Available in different materials, sizes, pressure ratings, and connection methods, valves can be matched with HDPE, PVC, PPR, steel, and other piping systems for water supply, irrigation, drainage, and industrial applications.
