Manual Universal NRV

Manual Universal NRV is a compact plumbing fitting which is used to make a unidirectional flow channels in industrial systems such as water treatment plants and other flow systems to prevent damages due to back pressure. This safety equipment is fabricated by using alloyed steel which gives higher strength and durability. The inlet and the outlet end of this heavy duty Manual Universal Non Return Valve are provided with internal threads to make leakproof non-permanent rigid connections.

1. Design and Configuration: The valve typically consists of a housing with an inlet and an outlet, designed to accommodate the flow of fluid in one direction. It contains an internal mechanism (such as a hinged flap, swinging disc, or spring-loaded poppet) that opens when the fluid flows in the intended direction and closes to prevent backflow.
2. Material: Universal non-return valves are commonly constructed from materials that are resistant to the specific type of fluid they are intended to handle. This can include materials like stainless steel, brass, bronze, PVC (polyvinyl chloride), or other corrosion-resistant materials.
3. Connection Types: They are available with various connection types such as threaded, flanged, welded, or compression fittings, making them adaptable to different piping systems.
4. Size Range: Universal non-return valves come in a range of sizes to suit different flow rates and applications, from small plumbing systems to large industrial pipelines.
5. Pressure and Temperature Ratings: These valves are designed to withstand specific pressure and temperature conditions based on the application. Manufacturers provide specifications indicating the maximum pressure and temperature the valve can handle.
6. Cracking Pressure: Cracking pressure refers to the minimum pressure required to open the valve and allow fluid flow. Different valves have different cracking pressures, which are essential to consider based on the system's requirements.
7. Maintenance and Service: Universal non-return valves are generally low-maintenance due to their simple design. However, periodic inspection and cleaning may be necessary to ensure optimal performance.
8. Application Compatibility: These valves are used in a wide range of applications, including water supply systems, wastewater systems, industrial processes, oil and gas pipelines, HVAC systems, and more.
9. Manual Operation: Unlike some other types of valves, universal non-return valves are usually operated passively by the flow of fluid. There is no need for external control; they respond to changes in fluid pressure.
10. Installation Orientation: Some non-return valves are sensitive to their installation orientation. It's important to install them in the correct direction to ensure proper functionality.
11. Compact and Space-Saving: These valves are generally compact, making them suitable for installations where space is limited.
12. Silent Operation: In most cases, these valves operate silently since they do not require external control or actuation.
13. Backflow Prevention: The primary function of a universal non-return valve is to prevent the backward flow of fluid, which could lead to contamination, damage, or disruptions in the system.
