Our high vacuum tri-clamp ball valve (GU Series) is a high-performance flow control solution engineered for both high vacuum and general positive pressure operating conditions. Designed with industry-leading flow conductance and versatile connection formats, this valve delivers reliable on/off control for critical process media across demanding industrial environments.
The working principle of this high flow conductance vacuum ball valve centers on a precision-machined spherical closure member. By rotating the ball 90 degrees via the valve stem, the flow path is fully opened or closed, enabling unobstructed media flow with minimal pressure drop in the open position, and bubble-tight shutoff in the closed position. The valve is available for manual handwheel operation, or fitted with an ISO5211 direct mounting platform for seamless integration of pneumatic or electric actuators, simplifying installation and enabling automated process control.
The valve’s full-bore, streamlined flow path minimizes flow resistance and turbulence, delivering exceptional high flow conductance to maximize process efficiency, even in high-cycle vacuum applications.
The integrated ISO5211 direct mounting platform eliminates the need for custom brackets, enabling fast, straightforward installation of pneumatic and electric actuators, while delivering a clean, compact footprint for space-constrained installations.
Every wetted component (body, bonnet, stem, ball) is manufactured from high-grade stainless steel, delivering superior corrosion resistance and long service life in harsh process environments. Multiple seal material options are available to match specific media and temperature requirements.
With an ultra-wide pressure range spanning high vacuum to positive pressure conditions, and support for any mounting orientation, this stainless steel high vacuum ball valve adapts seamlessly to diverse process layouts and operating requirements, with a low leakage rate that meets strict vacuum system standards.
This sanitary high vacuum ball valve is trusted across a wide range of precision process industries, including dairy processing, wine and beverage production, biotechnology, food and beverage manufacturing, pharmaceutical production, fine chemical processing, cosmetics manufacturing, new energy production, and semiconductor fabrication. It is ideal for applications requiring both high vacuum performance and sanitary, cleanable flow control, such as sterile pharmaceutical processing, semiconductor vacuum deposition systems, and food-grade CIP (Clean-in-Place) systems.
As a professional manufacturer of high-performance vacuum valves, Pioneer Valve delivers tailored solutions for industrial process teams and system integrators worldwide. We provide full pre-sales technical support to help you select the perfect valve configuration for your specific operating parameters, including custom pressure, temperature, connection, and actuation requirements. Our products undergo rigorous quality testing to ensure consistent vacuum performance and long-term reliability, with flexible delivery terms, transparent pricing, and responsive after-sales support to keep your operations running smoothly.
The valve is available for manual handwheel operation, or with an ISO5211 direct mounting platform for easy installation of pneumatic or electric actuators to support automated process control.
This high vacuum ball valve supports a minimum vacuum level down to 6.7×10⁻⁴ Pa across all standard connection types, meeting the requirements of most high vacuum process systems.
For high-temperature media, we offer PPL seals (supporting -30℃ to +260℃) and Viton seals, with standard PTFE seals available for general temperature applications up to 150℃.
Yes, this valve supports installation in any orientation, with no impact on performance or leakage rate, making it easy to integrate into complex process piping layouts.
