Tech Taylor Vacuum breaker

Product catalog summary

Introduction: The document discusses the potential for vacuum conditions in pipelines, particularly highlighting the issues with ABS piping, which is more prone to collapsing under vacuum than metal pipes. The document introduces the TECH-TAYLOR T1 valve as a solution to this problem.

Specifications: The TECH-TAYLOR T1 valve is available in a single size of 4 inches (100mm) and can handle line pressures up to 200 psig. It is a free ball check valve with an elastomer-lined housing, designed in three sections for easy maintenance. The ball is elastomer-covered and designed to float in slurry.

Functionality: The valve is installed directly off the tailings line. When the pipeline is not in operation, the ball rests at the bottom of the housing, allowing air to enter the pipeline and open it to the atmosphere. The open area around the ball is approximately double the ball area, ensuring unrestricted airflow.

Operation: As the slurry column advances, it raises the ball to its seating position, sealing the T1 valve. When the pump stops and the system pressure shifts from positive to negative, the ball drops from its seating position, allowing air to enter the pipeline and break the vacuum.

Catalog excerpts

As the sketch below shows, all pipe lines have the potential to create vacuum conditions. The widespread use of ABS piping has put the spot light on this problem since collapsing happens at lower vacuums than metal pipe. While siphon breakers are available for use in clear liquids, abrasive slurries present serious difficulties. The TECH-TAYLOR T1 is available in only one size, 4 inch (100mm), and is suitable for line pressures up to 200 psig. Like the widely used T2 series, this is a free ball check valve using an elastomer lined housing built in 3 sections for easy maintenance. The ball is...
