HVX valves are physically the largest valves. A larger port internal diameter allows increased fluid flows even with moderately viscous fluids. HVX valves can be used free standing or panel-mounted using an optional locking nut, Part # 35121. 6- and 8-port distribution and loop valves are available only in the HVX body style.
