Accurate temperature control:
The tolerance of setting temperature of Wisdom T/P relief valve is ±2°C only, far better than American and European standard of ±6°C. For instance, the practical working temperature of 95°C valve is betwwen 93°C till 97°C. As a result Wisdom T/P relief valves are much more safe, besides avoid valve opens prematurely.
Higher discharge rate:
The Wisdom probe piston rises quite fast: since 93°C, for every 1°C temperature increases, the piston rises 1mm; to attribute higher discharge rate.
In order to increase its thermal sensitivity, certain copper powder must been mixed during its fabrication of wax T/P relief valve probes. After certain cycles of melting-solidification, those copper powders will be sinked down toward the bottom of wax, causing the valve failure. While Wisdom probes no need any additive, with supreme reliability and prolonged service life.
