Designed for Efficient Pressure Control and Safe Maintenance

Our single block and bleed ball valve (SBB) is designed to provide reliable isolation and pressure relief in a compact and cost-effective package. This innovative valve combines a main isolation valve with an integrated bleed port, allowing operators to safely isolate pipeline sections and vent trapped pressure or fluid through a single space-saving unit. The SBB design offers significant advantages over traditional multi-valve configurations and is ideal for standard industrial applications where safety and efficiency are paramount.

Engineered with Simple, Effective Sealing Technology

SBB ball valves feature a floating ball design, allowing the ball to move freely within the valve body.  When closed, the ball seats tightly against the downstream seat, creating a reliable seal. This pressure-assisted sealing mechanism ensures reliable performance under various operating conditions. PTFE or reinforced PTFE seats offer excellent chemical resistance and low friction characteristics, while the chrome-plated or stainless steel ball ensures smooth rotation and a long service life. An integrated vent valve safely releases trapped pressure between the isolation valve and the downstream system, ensuring the pressure is reduced to zero before maintenance operations.

Delivering Enhanced Safety and Operational Efficiency

Choosing SBB ball valves means investing in a proven method to effectively reduce risks during pipeline maintenance. Their integrated design eliminates the need for multiple separate valves, gaskets, or blind flanges, simplifying the piping system, reducing potential leak points, and lowering installation and lifecycle costs. The pressure relief and cavity pressure monitoring capabilities provide reliable seal integrity verification, enhancing lockout/tagout (LOTO) procedures and ensuring compliance with industry safety standards. This operational reliability protects personnel, the environment, and valuable assets.

Built for Standard Industrial Applications

Our SBB ball valves are suitable for a wide range of applications, including water treatment systems, oil and gas pipelines, chemical plants, and industrial utility systems. These valves are available in sizes ranging from 2 inch to 56 inches (DN50-DN1400), with pressure ratings from Class 150 to Class 2500, and can withstand temperatures from -101°C to 350°C. They are compatible with various media, including water, oil, gas, steam, and mildly corrosive chemicals, making them an ideal solution for general industrial applications.

Equipped with Essential Safety Features

Each SBB ball valve is equipped with standard safety features, such as a blow-out proof stem design to prevent the stem from ejecting under high pressure; a fire-safe design (optional); and an anti-static device for handling flammable media. Full-bore or reduced-bore design options meet different flow requirements, while flanged, threaded, or socket-weld end connections ensure secure installation in various piping systems.

Manufactured to International Standards

Our SBB ball valves comply with API, ASME, and ISO standards, ensuring product quality and reliability. These valves prioritize cost-effectiveness and performance, offering an excellent balance of quality and value in standard industrial applications where double isolation is not required but basic isolation and pressure relief functions are necessary.
