“The big payoff is in downtime -- the drastic reduction from hours to minutes translates into greater efficiency for any operation.” - Scott Sargent, product manager for Victaulic

Victaulic, the world’s leading manufacturer of mechanical pipe-joining systems, today announced the launch of the Series 795 Knife Gate Valve, the industry's first in-line maintenance knife gate valve. The new valve simplifies installation and maintenance, reduces downtime and improves worker safety.

The Series 795 Knife Gate Valve 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 lines for slurry and tailings or cyclones. It alleviates a longstanding industry pain point: the time-consuming, labor-intensive process of removing the entire valve from the pipeline 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. In fact, one Montana mining company beta testing the Series 795 saw maintenance that once required hours of downtime reduced to minutes.

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.

“After we installed the new valve, it has run like a dream,” said Amy French, senior maintenance planner at Golden Sunlight Mining in Montana. “We have been so impressed with this unit we are looking at purchasing additional valves.”

The Victaulic Series 795 Knife Gate Valve joins either grooved end carbon steel or plain end HDPE pipe. It is available in sizes 3-12 inches (80-300 millimeters) and rated to 150 psi | 1034 kPa | 10 bar.

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

Additional features include:
●    Installation-ReadyTM 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
●    Anti-rotation screws for full 360 installation positioning
