How to determine internal leakage of valve?
4-6 hours after the valve is closed, use an infrared thermometer to measure the temperature of the valve stem (near the valve body) or the metal temperature 150mm downstream of the valve body. If it is greater than 70°C, it is considered "internal leakage". This judgment method is applicable to most internal leakage valves.
