The Vic-Ball Super Duplex Valve Series 726D from Victaulic
This two-piece, end-entry valve features a floating ball for lower torque requirements.
In addition to providing easier, faster and safer installation than flanged and butt-weld valves, it can tolerate pressures of up to 8,200 kPa (1,200 psi). Connected by the Victaulic Style 489DX rigid coupling, which is comprised of only 2 bolts to create a secure joint, field installation is very efficient for both high-pressure and low-pressure applications.
Since their introduction to the market more than 50 years ago, triple offset valves (TOVs), which are also known as triple eccentric valves, have continued to evolve, while uses for this type of valve have expanded across multiple industries.
Wastewater systems present many challenges to pumps and valves because the flow can contain grit, solids and debris, depending where in the process the equipment is located.
For a very long time, the idea has existed that a trunnion-mounted ball valve can be opened under full differential pressure if the piping system can withstand the rapid increase in pressure and the forces induced by it.
