Full Bore Check Valve Suppliers – SS, Brass & CI Types for Industrial Use
Full Bore Check Valve Suppliers – SS, Brass & CI Types for Industrial Use
Full bore check valves, also known as full port non-return valves (NRVs), are designed to provide minimal flow resistance and prevent backflow in piping systems. These valves feature an internal passage equivalent to the diameter of the pipe, ensuring minimal pressure drop and efficient fluid handling. Widely used in process, water, fire, HVAC, and industrial systems, full bore NRVs are available in various materials including stainless steel, cast iron, and brass.
What is a Full Bore Check Valve?
It is a one-way valve with an internal passage equal to the nominal bore size of the pipeline. It allows fluid to pass in one direction and automatically prevents reverse flow using a lift, swing, or wafer mechanism.
Benefits of Full Bore NRVs
- Maximum flow with negligible pressure loss
- Reduces energy consumption in pumping systems
- Prevents clogging due to uniform bore
- Ideal for high flow and low-pressure drop applications
Common Types of Full Bore Check Valves
- Swing Type: Hinged disc swings open with flow
- Lift Type: Disc lifts vertically under pressure
- Wafer Type: Slim and compact with spring disc
- Screwed Type: Threaded for domestic and low-pressure use
- Flanged End: Heavy-duty application in industries

FAQs – Full Bore Check Valves
Q1. What does full bore mean in check valves?
It means the valve opening equals the pipe’s internal diameter, allowing full flow with minimal loss.
Q2. Are full bore valves better than reduced bore?
Yes, for flow efficiency and low-pressure applications. Reduced bore may be used for throttling or cost-saving.
Q3. Where are full bore NRVs used?
Water plants, boiler systems, process industries, fire safety, HVAC loops, etc.
Q4. Can I install them vertically?
Most lift check valves can be installed vertically (flow upward). Swing types usually prefer horizontal lines.
Q5. Are SS 316 valves worth the cost?
Yes, they offer corrosion resistance and are ideal for aggressive fluids, chemicals, and pharma use.
