Stainless Steel Non Return Valve

SS 304 NRV Valve and Pneumatic Non-Return Valves suppliers in UAE

Stainless steel Non Return valve

What is stainless steel non return valve?

The non return valve allows the fluid to flow only in one direction. It should be fitted in the right place to ensure fluid flows in the right direction, but they have a big pressure drop. The stainless steel non return valve prevents the reverse flow caused due to pressure conditions. They can be used for isolating a boiler during a shutdown and helping it to restart operation after maintenance.

SS 304 non return valve is an important safety device as it restricts steam flow from header to the boiler as that can cause severe accidents. They are flow sensitive and rely on the gas flow to execute their opening and closing operations. As per ASME standard, one SS316 non return valve is needed per boiler for high pressure applications.

The flanged and screwed end non return valves comes with different working pressure and thread type to suit your project requirements. The hydraulic non return valve can be found in industries like chemical, petrochemical, shipping, paper manufacturing, etc.

What is the purpose of a SS non-return valve in a water pipeline?

The SS non return valve enables the fluid to flow only in the right directions and prevents any kind of reverse flow. They are available in different sizes to suit your requirements and are generally small in size. Their simple design not only makes installation easy but also increases its affordability.

Do non return valves restrict flow?

The NRV valve restricts 100% flow in one direction as that is the main purpose of using them. On the other direction, they may cause some amount of medium flow loss as it takes some effort to shift the valve from closed to open situation.

Can a Pneumatic Non-Return Valve Affect Water pressure?

When water flows through the pneumatic non-return valves, a pressure drop can occur and that must be considered while designing the valve. There are different types of NRV valves like swing, spring loaded, clapper, etc. The pressure drop caused by your pneumatic NRV valve will depend on its type.

How do I know if my non-return valve is working?

The failure of the 1/2 stainless steel non return valve is indicated by symptoms like vibration, losing some internal parts, reverse flow, and excessive wear or damage of the components. Also check your NRV ball valve for any noise as that is too a sign for breakdown. With close inspections and regular maintenance, you can be rest assured about the working status of your NRV.

Difference between swing type non-return valve & wafer non return valve

The swing type non-return valve has molded bodies around the disc opening area. Whereas, wafer type non return valve is used when installation is need in very small space. Also, wafer can restrict higher flow percentage than the swing type.
