Description
Check Valve is a valve designed to allow fluid to flow in only one direction and automatically prevent backflow. It helps maintain system stability, reduces damage from reverse pressure, and protects equipment from incorrect flow direction.
Features of Check Valve
Prevents backflow of fluids
Operates automatically without additional energy
Reduces water hammer and pressure surges caused by reverse flow
Made from durable, corrosion-resistant materials capable of handling high pressure
Suitable for use with liquids, gases, and steam
Types of Check Valve
Swing Check Valve: Uses a hinged disc that swings open and closes with fluid pressure
Lift Check Valve: Features a piston or disc that lifts with forward flow and drops to block backflow
Ball Check Valve: Uses a ball to control flow direction, sealing automatically when flow reverses
Dual Plate Check Valve: Uses two spring-loaded plates to reduce pressure loss and minimize shock
Wafer Check Valve: Compact and lightweight, designed for space-saving installations
Applications
Water supply and wastewater treatment systems
Oil and gas pipelines
Steam systems and heating equipment
Chemical and petrochemical industries
Pumping systems and pressure control networks
