High Pressure Instrument Ball Valve

Application Note:
** O-Ring face seal connections with HNBR seals optimized for CNG fueling systems **

1/4” - 3/4" NPT
1/4” - 3/4" Dual Ferrule Tube
3/8" and 1/2" O'Rings Face Seal

0 – 6000 Psig (413 Bar)


High Pressure Instrument Ball Valves offer reliable 1/4-turn shutoff for pressures up to 6,000 Psig (413 bar). These valves feature a Micro-Finished Floating Ball design to provide a positive seal in both directions. Series IBV Instrument Ball Valves also feature a “straight-through” flow path to ensure high flows with minimum pressure drop. The valves are designed to operate with a low operation torque while providing a long service life. All valve configurations can be panel mounted.

Technical Data

  • Pressure Rating: 6,000 PSI (413 Bar) at 100°F (3:1 SF)1
    • Per NFPA 52 (2013): 4,750 PSI (328 Bar)
    • Per ASME B31.3 (2012): 4,400 PSI (303 Bar)
  • Temperature Rating: -65° to 200°F (-54° to 93°C)
  • Leakage: < 0.1 SCCM @ 2,100 PSIG (145 Bar)
    • 100% Factory Tested for Leakage
    • Note: For a leak-free stem seal at pressures higher than 2,100 PSI or after prolonged use, additional tightening of the stem packing may be required.
  • Flow Coefficients: per size, see Dimensional Data Table

Ordering Information

PROPER COMPONENT SELECTION - When specifying a component, the total system design must be considered to ensure safe and trouble-free performance. Intended component function, materials compatibility, pressure ratings, installation, environment and maintenance are the responsibility of the system designer.
