Reduced Bore Ball Valve

Reduced Bore Ball Valve is designed with a partially reduced internal bore, offering a balance between flow capacity, cost efficiency, and structural strength. Compared with full bore design, it provides slightly higher flow resistance but significantly reduces overall weight and manufacturing cost. It is widely used in general industrial applications where full flow is not critical, such as water treatment, oil & gas, chemical processing, and utility pipelines. The valve features robust sealing performance, low operating torque, and reliable shut-off capability under medium to high pressure conditions. Available in carbon steel, stainless steel, and alloy materials, it complies with API 6D and ASME B16.34 standards, ensuring long service life and dependable performance in demanding environments.

Reduced Bore Design

The reduced port configuration decreases valve weight and material usage while providing sufficient flow capacity for general industrial applications, offering an economical alternative to full bore ball valves.

Compact and Cost-Effective Construction

A smaller internal bore allows for a more compact valve body, reducing installation space, transportation costs, and overall project investment.

Low Operating Torque

Optimized ball and seat geometry minimizes operating torque, enabling smooth quarter-turn operation and compatibility with manual, electric, or pneumatic actuators.

Fire-Safe and Anti-Static Design (Optional)

Available with fire-safe construction conforming to API 607/API 6FA and anti-static devices to enhance operational safety in flammable or hazardous service.

Blowout-Proof Stem

An internally mounted stem prevents accidental stem ejection under pressure, improving operational safety and ensuring long-term reliability.

Multiple End Connection Options

Available with flanged (RF/RTJ), butt weld (BW), socket weld (SW), and threaded (NPT/BSP) ends to suit various piping systems and installation requirements.

Wide Material Selection

Manufactured in carbon steel, stainless steel, duplex stainless steel, and alloy steel to meet the demands of corrosive, high-pressure, and high-temperature applications.

Easy Automation

Designed with an ISO 5211 mounting pad (optional), allowing direct installation of pneumatic or electric actuators without additional brackets.

Versatile Industrial Applications

Suitable for oil & gas, petrochemical, chemical processing, power generation, water treatment, and other industrial pipeline systems where a reduced-port valve provides the optimal balance between performance and cost.
