Frequently Asked Questions

What is a Cast Iron Check Valve?

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

What are the applications of Cast Iron Check Valve BS 5154?

Cast Iron Check Valve BS 5154 is used in water supply lines, pump discharges, irrigation systems, and industrial process lines to prevent backflow that could damage equipment or contaminate the system.

Why use a bolted cover design?

Bolted cover design provides better sealing and higher pressure capability compared to screwed covers. It allows for easier maintenance and inspection of internal components.

What is the maximum allowable backflow pressure?

Check valves should not be used to prevent backflow under static conditions. They are designed to allow forward flow with minimal pressure drop and close when flow reverses. For critical backflow prevention, a separate isolation valve should be used.

Where can I buy Cast Iron Check Valve in India?
