Abstract: A valve having means for measuring leakage through the valve. The valve body has a small heater in the leakage flow path downstream of the upstream seal and a heat sensor upstream of the downstream seal in the leakage path; fluid that leaks past the upstream seal is heated and its presence detected by the heat sensor which then indicates the fact that the valve is leaking.
