What Are the Common Types of Drain Valve

This article reviews common types of drainage valves and their applications: gate valves (low flow resistance, suitable for high-flow wastewater containing solids); butterfly valves (compact and lightweight, fast operation, suitable for wastewater treatment); ball valves (excellent sealing, low flow resistance, suitable for viscous or crystallizing media); check valves (prevent backflow, ensure pipeline safety); control valves (precise control of flow rate and pressure, used for complex wastewater). Valve selection requires a comprehensive evaluation of fluid characteristics (temperature, pressure, chemical composition, and solid particles), pipeline dimensions, and operational maintenance to enhance drainage efficiency and environmental safety.
