In Reply to: What is the ultimate steam isolation valve? posted by Mike S on December 14, 2001 at 00:22:27:
: This question must be 150 years old. But what is the best valve design to give reliable, without question steam shut-off (@1500kpa)that will last 20 years without failure? I'm sick and tired of replacing ball, gate and globe valves that get less than a years leak-free service. Does anyone want to stake their reputation on their advice?
