HAM-LET® H-6800 3-Piece Ball Valve

The Ham-Let® H-6800 Series is a -performance instrumentation ball valve for general service and instrumentation panels. The 2-way valves offer tight shutoff, long-life service and low operating torque. The 3-way valve is designed for diverting only, and not for shutoff service, the inlet is from the bottom port only and is designed to be fully opened to any of the side ports. The 3-way valve does offer long-life service and low operating torque.

The H-6800 Series is rated to maximum 6000 psig and performs on/off or diverter service.


  • The H-6800 design has been tested for Burst and Proof.
  • Standard testing for each H-6800 valve includes testing with nitrogen at 80 & 1000 psig.
  • Each valve is tested for leakage through the shell, packing and ball seats.
  • Maximum allowable leakage across the seat is 0.1 std cc/min.

Packing Adjustment:

  • Due to the varied service applications of the valve, packing adjustment may occasionally be necessary.
  • Packing is factory adjusted to 1000 psig service. Initial packing adjustment is recommended after installation and prior to start-up.
  • Please find more information on H-500 under Installation Instructions.
