In this context, valves are not secondary components of water infrastructure — they are the control points that determine whether water reaches its final destination with the correct quality, pressure, and flow, and whether effluents are efficiently treated before being discharged.\n\u003c\/p\u003e\n\u003cp\u003e\n  Cematic supplies valves for the Mexican hydraulic sector in all its diversity: municipal and state operating agencies (SACMEX, SAPAL, SIAPA, JAPAC, and similar), drinking water and wastewater treatment plants, agricultural and technical irrigation systems, industries with process water demand, and building and commercial infrastructure construction with hydraulic systems.
