Full Port Ball Valves
U.S. Valve's full port ball valves are engineered to deliver lower pressure drop and more laminar flow than conventional ball valves — making them the preferred choice for demanding industrial, HVAC, and fluid control applications. Available in 316 stainless steel (1,000 WOG), brass with chrome-plated ball (600 WOG), and nickel-plated brass (400 WOG) construction, every valve is designed, manufactured, and tested to MSS-SP110.

USV IRX-B — Ball & IR Check Valve Combo for Data Center Cooling
U.S. Valve's newest innovation, the USV IRX-B, is a patented Ball & IR Check Valve Combo purpose-engineered for AI data center Coolant Distribution Unit (CDU) systems. This dual-function valve integrates a quarter-turn ball isolation valve and an internally retained (IR) check valve into a single compact body — reducing valve footprint by 51% or more while maintaining maximum flow and minimum pressure drop.

Key benefits of the combo design include:
- Footprint reduction — Combining two valves into one body reduces valve footprint by 51% or more, freeing up space in dense server racks and simplifying manifold layouts.
- Maximum flow, minimum pressure drop — Maintains the same high flow and low pressure drop as a standalone IR check valve, supporting lower pump energy use and improved cooling efficiency.
- Combined isolation + backflow protection — The ball element allows positive isolation for service, while the IR check element protects against reverse flow, water hammer, and pressure spikes.
- Fewer leak points — Consolidating two components into one reduces the number of fittings and joints that must be sealed and inspected.
- Custom engineering — Available in tri-clamp, NPT, flange, wafer, or custom end connections, with material and elastomer selection based on coolant type and temperature profile.
This valve is engineered to safeguard chips, cold plates, and other sensitive components during startup, shutdown, and upset conditions — a critical requirement in mission-critical AI data center environments.

Sanitary & Tri-Clamp Ball Valves
U.S. Valve engineers sanitary ball valves built to ASME BPE standards for hygienic process industries, including food and beverage, pharmaceutical, biotech, and cosmetics manufacturing. Featuring Tri-Clamp (sanitary) end connections for fast, tool-free disassembly, these valves are available in 316 and 304 stainless steel and are designed to meet the surface finish and cleanability requirements of sanitary process systems.
Sanitary ball valve capabilities include:
- Tri-Clamp / sanitary end connections built to BPE fittings standards for quick, repeatable connections in wash-down environments
- 316 and 304 stainless steel construction for corrosion resistance and CIP/SIP compatibility
- Crevice-free, full-port flow paths that meet sanitary tube and process piping requirements
- Custom porting and actuation options for integration with existing sanitary process parts

Full Port Ball Valves vs. Standard (Reduced Port) Ball Valves
Full port ball valves — also called full bore ball valves — feature an oversized ball with a bore that matches the pipe's full inner diameter. Standard ball valves use a smaller ball bore, which creates a restriction point and increases pressure drop.
U.S. Valve's full port design delivers:
- Lower pressure drop across the valve
- Higher Cv (flow coefficient) for greater flow capacity
- Reduced turbulence and associated noise
- Easier pigging and line cleaning in process systems
For applications where minimizing pressure drop is a priority — such as compressed air systems, data center cooling loops, and water & wastewater treatment — a full port ball valve is the superior choice.
Frequently Asked Questions About Full Port Ball Valves
What is a full port ball valve?
A full port ball valve has an oversized bore that matches the pipe's inner diameter, providing unrestricted flow and minimal pressure drop. Unlike standard reduced-port valves, this design eliminates a flow restriction point, resulting in a higher Cv, less turbulence, and improved energy efficiency — making it ideal for compressed air, HVAC, and industrial fluid applications.
What is the difference between a ball valve and a gate valve?
Ball valves use a quarter-turn mechanism to open and close quickly, forming a bubble-tight PTFE seal ideal for frequent cycling. Gate valves require multiple turns, are slower to actuate, and suit infrequent, full-open service. Ball valves offer tighter shutoff, lower maintenance needs, and longer service life for most modern industrial and commercial piping applications.
What materials are industrial ball valves available in?
Industrial ball valves are most commonly available in 316 stainless steel, brass, and nickel-plated brass. Stainless steel handles corrosive media and high-pressure service up to 1,000 WOG; brass is suited for water, oil, and gas at 600 WOG; nickel-plated brass covers moderate-duty applications. Material selection should align with fluid type, operating pressure, and temperature range.
What is a Ball & IR Check Valve Combo?
A Ball & IR Check Valve Combo integrates a quarter-turn ball isolation valve with an internally retained (IR) check valve in a single body. Used primarily in AI data center cooling (CDU) systems, it reduces valve footprint by over 51%, maintains low pressure drop, and combines shut-off isolation with backflow protection in one compact component.
Do you offer sanitary or Tri-Clamp ball valves?
U.S. Valve engineers sanitary ball valves with Tri-Clamp end connections built to ASME BPE standards, available in 316 and 304 stainless steel for hygienic process applications. Contact an application engineer to discuss your sanitary process parts and connection requirements.
