Frequently Asked Questions

What is a Stainless Steel Check Valve?

A Stainless Steel Check Valve allows flow in one direction only, automatically preventing backflow. The horizontal swing type uses a disc that swings open with forward flow and closes when flow reverses.

What are the applications of SS Check Valve?

Stainless Steel Check Valve CF8 is used in chemical processing, food & beverage, pharmaceutical, and water treatment to protect pumps and equipment from backflow damage.

What is the advantage of bolted cover design?

Bolted cover design provides better sealing for higher pressure applications and allows easier access for maintenance compared to threaded covers.

Can check valves be used for dead-end service?

Check valves should not be used to isolate sections of pipe under static conditions. They are designed for flow applications and may not seal properly under no-flow conditions.

Where can I buy Stainless Steel Check Valve in India?
