  • Establishing a new method for determining valve flow coefficient
    . As an example, a ball-type valve has a very low xT, well below 1 2, whereas a globe-style valve would have an xT significantly higher than 1 2. As shown in Figure 1, valve geometry determines the choked flow pressure ratio. Valves with complicated or circuitous flow paths tend to have numerically high xT
  • Step Closer to the Holy Grail (.pdf)
    Valve manufacturers have been improving, modifying and redesigning valves for years in an attempt to reach a zero leakage valve. People have tried Gate valves with special hard facings or special wedging actions, ball valves with two seats or seats made from elastomers, seats of all types of metals
