Specifications for the individual testing requirements of control valves

2012-06-30 View Original

Thread Content

Which specification provides instructions for pressure testing control valves? Is it based on the requirements for general valves outlined in 50235 for random inspections?
Reply #2 2012-06-30
The pressure testing of control valves differs from that of ordinary valves, as control valves have a specified allowable leakage rate. For example, the leakage rate of pneumatic control valves is related to the volume of the valve body, while the strength of the valve body can be determined using the standards applicable to ordinary valves
