Control Valve Seat Leakage Calculation at Mary Morena blog

Control Valve Seat Leakage Calculation. A control valve needs a device to convert the electrical signal that the controller, which is typically a plc, sends in order for it to function. The testing methods for calculating a control valve leakage depend on the type you’re using and the valve elements. Because this valve is meant to throttle rather than shut entirely, each one has a different capacity to shut off, which causes the control valve seat leakage must be calculated. The “bubble test” used for class vi seat leakage is based on the leakage rate of air or nitrogen gas past the closed valve seat as measured by counting the rate of gas bubbles escaping a bubble. 1.1 this standard establishes a series of seat leakage classes for control valves and defines the test procedures. Control valves are designed to throttle flows and they are not necessary able to close 100% with. Seat leakage classification through control valves. Here are some of the most commonly performed.
