FAQs of Non Return Check Valve:

Q: How do Non Return Check Valves work in industrial applications?

A: Non Return Check Valves operate by allowing media to flow in only one direction, preventing backflow that could damage equipment or disrupt system performance. The valve opens under forward pressure and automatically closes if the flow reverses, providing reliable protection in pipelines carrying water, oil, gas, chemicals, or steam.

Q: What connection and size options are available for these valves?

A: Our valves are offered with flanged, screwed, or socket welded end connections, following standards such as ANSI, DIN, and BS. Port sizes range from 1/2 inch to 12 inches (DN15 to DN300), accommodating a broad spectrum of pipeline requirements.

Q: When should I install a Non Return Check Valve in my system?

A: Install these valves wherever you need to prevent reverse flow, which can occur due to pump shutdowns, pressure surges, or gravity. Common installation points include pump outlets, branching pipelines, or inlets to sensitive equipment. The mounting can be either horizontal or vertical, depending on space and pipeline configuration.

Q: Where can these valves be used?

A: Designed for versatile use, these Non Return Check Valves are suitable for industrial plants, water treatment facilities, HVAC systems, oil and gas pipelines, chemical processing, and steam distribution networks. Their robust construction and chemical compatibility make them suitable for a wide range of environments.

Q: What is the process for inspection and testing of these valves?

A: Each valve undergoes rigorous inspection and testing as per API 598 standards, which includes pressure testing for both shell and seat integrity, as well as functional tests to ensure consistent operation before shipment.

Q: What benefits do epoxy painted or powder coated valves offer?

A: Epoxy painting and powder coating provide excellent protection against corrosion, extending the valves lifespan even in aggressive or moist environments. This ensures reliable operation and reduces maintenance costs over time.

Q: How do I select the right material and sealing for my application?

A: Material selectioncast iron, cast steel, stainless steel, or bronzeshould be based on the media type and operating conditions. For sealing, options like EPDM, NBR, or PTFE are provided, each tailored to suit specific fluids and temperature/pressure requirements.
