Ball Valve

Model Number

V82

Features

• Sealing is achieved without system pressure
• Bi-directional flow
• Pressure up to 3000 psig (206bar)
• 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.

Materials of Construction

Molybdenum disulfide with hydrocarbon coating

Operation & Packing Adjustment

• V82 valves are designed to control fluid in full open and closed position; using V82 valves to throttle the flow may reduce the valve life.
• Valves that have not been actuated for a period of time may have a higher initial actuation torque.
• Every valve working pressure is adjusted for factory test at 1000 psig(68.9bar) @21°C(70°G). For use in higher pressure, the valve packing may be required for re-adjustment.
• Packing adjustment may be required during the valve in service.

Application

• Analytical market requiring a valve with lowest dead space to prevent fluid entrapment which can cause contamination.
• Control Sampling Systems, and Process Instrumentation market requiring a valve with compact size, high flow capacity and directional indication of flow.

Factory Test

• Every V82 series ball valve is factory tested with the nitrogen at 1000 psig(68.9 bar) for leakage to a maximum allowable leak rate of 0.1 sccm/min. at all of the seals.
