What is a Bronze Check Valve?

A Bronze Check Valve is a unidirectional valve that allows fluid to flow in one direction only, automatically preventing backflow. The horizontal swing type Check Valve uses a disc that swings open with forward flow and closes by gravity when flow reverses.

What are the applications of Bronze Check Valve IS 778?

Bronze Check Valve IS 778 is used in water supply lines, pump discharges, steam return lines, oil pipelines, and HVAC systems to prevent backflow that could damage equipment or contaminate the system.

What is the difference between screwed cover and bolted cover Check Valve?

Screwed cover Check Valves have a cover that threads into the body, suitable for lower pressure applications up to Class 1 (1.0 MPa). Bolted cover designs are used for higher pressures and larger sizes, providing better access for maintenance.

What materials are used in Bronze Check Valve construction?

The Bronze Check Valve uses Bronze IS 318 Grade LTB2 for body and cover, with bronze disc and hinge. The swing-type design provides minimal restriction to flow and reliable backflow prevention.
