FAQ's of SS Non Return Valve:

Q: How is an SS non return valve installed in different piping systems?

A: Installation is straightforward-these valves come with screwed (BSP/NPT), socket weld, or flanged end connections for seamless integration into various piping setups. They can be mounted horizontally or vertically and suit manual flow control without external systems.

Q: What media are compatible with the SS non return valve?

A: These valves are suitable for potable water, oils, steam, and non-corrosive liquids. The selection of seat material (PTFE, Viton, or metal) ensures reliable sealing and chemical compatibility across a wide range of applications.

Q: When should I use a swing type or lift type non return valve?

A: Swing type is preferred for larger flow rates and minimal pressure drop, while lift type is ideal for applications requiring tighter sealing and higher pressure ratings. Use swing type for horizontal installations and lift type for vertical or when backflow prevention is critical.

Q: Where can SS non return valves be applied?

A: These valves are widely used in water treatment, oil refineries, chemical plants, steam lines, and general fluid management systems, making them suitable for industrial, commercial, and residential sectors in India and overseas.

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

A: Valves are hydrostatically tested up to 20 bar as per ANSI/DIN/BS/JIS standards. Each product adheres to ISO 9001:2015 and CE certification requirements, validating quality, safety, and international compliance.

Q: How does the valve prevent backflow and what are its benefits?

A: As a check valve, it allows fluid to flow in one direction only, automatically stopping reverse flow. This prevents damage, contamination, and costly downtime, offering dependable backflow prevention in fluid systems.

Q: What maintenance is required for SS non return valves and what is their expected lifespan?

A: These valves feature polished or satin finishes and corrosion-resistant stainless steel construction, requiring minimal maintenance. With heavy-duty components and quality seals, they provide a long service life with low operational costs.
