About High Pressure NRV Valve Supplier Narmada India

How does a non-return valve work?

A non-return valve usually has only two openings in the body, with a closing member between them. When fluid enters the valve, its pressure opens the closing mechanism. If the fluid attempts to flow back through the valve in the wrong direction, the closing member is forced back over the entrance of the valve, preventing any flow.

Our Non-return valves work automatically, which means that most are not controlled by a person or an external control but by the media flow itself. Depending on precisely what a non-return valve is used for, where it is used, the media flow, and the budget available, various designs are available according to the specific application. Types of non-return valves include those designed using a diaphragm, a swing or tilting disc, a stop, a lift, or a ball non-return valve.

Precision Engineered for Diverse Applications

Our non return valves excel across various sectors including water treatment, chemical processing, oil, gas, air, and power industries. Available in compact wafer or swing/lift check configurations, they are designed for both horizontal and vertical installation. Their versatile material and coating options, such as fusion bonded epoxy and powder coating, ensure enhanced durability against corrosion and chemicals.


Comprehensive Compliance and Quality Assurance

Each valve adheres to stringent international standards including IS:5312, API 594, and BS1868. They undergo rigorous testing, with bodies rated at 1.5x and seats at 1.1x the nominal pressure. These procedures certify our products' performance, reliability, and safety, further underlined by our robust quality control processes.
