Victaulic to Introduce Industry’s First In-Line Maintenance Knife Gate Valve for HDPE Pipe

Series 906 Pneumatic 1

Victaulic, the world’s leading manufacturer of mechanical pipe-joining systems, will be introducing its new Series 906 Knife Gate Valve this month, the industry’s first in-line maintenance knife gate valve for HDPE pipe. The new valve simplifies installation and maintenance, reduces downtime and improves worker safety.

The Series 906 Knife Gate Valve for HDPE Pipe is ideal for fluid lines containing solids or abrasive materials common in wastewater treatment, hydroelectric power generation, mining, and other industrial settings with applications such as slurry and tailings lines or cyclones. It alleviates a long-standing industry pain point: the time-consuming, labor-intensive process of removing the entire valve from the pipeline service to facilitate maintenance, rebuilding and repair.

The new valve’s innovative design can reduce maintenance downtime by up to 95 percent and generate up to 60 percent savings in annual maintenance costs.

Victaulic developed advanced technology that encloses all wear parts into a single seat cartridge kit, which greatly simplifies maintenance. The design allows the valve to remain installed through ongoing maintenance cycles.

The new valve improves worker safety because only one component has to be replaced versus removing the entire valve from the pipeline. This first-of-its-kind, revolutionary design eliminates the need for rigging with heavy chains and pulleys swinging over the heads of maintenance crews.

The Victaulic Series 906 Knife Gate Valve joins plain end HDPE pipe. It is available in sizes 3 to 8 in. and is rated to 150 psi | 1034 kPa | 10 bar, or the maximum rating of the HDPE pipe, whichever is lower.

“This is the first knife gate valve that can be maintained in-line without having to disconnect the valve from a piping system for repair or rebuild of worn parts,” said Scott Sargent, product manager for Victaulic. “The big payoff is in downtime – the drastic reduction of hours to minutes translates into greater efficiency for any operation.”

Additional features include:
● Installation-Ready integrated coupling design.
● A self-clearing seat that eliminates debris pushing to the floor.
● Unidirectional polyurethane seat that is highly resistant to abrasive wear.
● Flush port in lower housing for easy valve cleaning.
