“Two-position valves used for safety interlock protection shall not be equipped with a handwheel mechanism. 1. What is a two-position valve?
Reply #22020-05-11
A two-position system generally refers to having only two states: fully open and fully closed! I would like to ask, what would you do if the interlocked valve does not operate properly?
