Bidirectionality in Isolation Valves
There are many types of valves used to isolate process flow. Each valve type has its own ability when it is fully closed and in isolation mode. The degree of tightness varies with valve type, make, media,
Valve Misconceptions
Allowable Leakage vs. Zero Leakage vs. Bubble Tight
Valve leakage is one of the main issues in industrial processes. Different valve leakage standards are specified by different organizations. Valves go through pressure tests which determine if they provide allowable leakage, zero leakage, or are bubble
Class 150 Does Not Equal 150 psig
Pressure-Temperature Ratings for Valves When it comes to valves, there are guidelines in place to protect workers and the environment from valve failures and leakage. In this example, we are talking about how much operating pressure a
