V 82 Ball Valves Design Features

• Sealing is achieved without system pressure
• Bi-directional flow
• Pressure up to 3000 psig (206 bar)
• Lowest dead space design
• Nylon Directional handle – indicates the flow through the valve.
• Panel mounting nut – is standard and permits valve to panel or actuator.
• Top-loaded packing – allows packing adjustment with the valve in-line.
• Capsule packing – fills voids in the valve body and prevents fluid entrapment. – allows lowest dead space.
• Support rings and discs – retains the capsule packing and prevent cold flow.
• Integral ball stem – machined from single piece bar stock. – eliminates the backlash during handle actuation.
• One-piece body – reduces the number of potential leak points.

V 83 Design Features

• Pressure and temperature compensation seat design.
• Swing-out design for fast and easy maintenance with the valve in-line.
