Pneumatic valve and thermal type thermostat hydrophobic hydrophobic pneumatic valve

the thermocouple hydrophobic pneumatic - valve is lower than the saturated steam temperature ~ - - - - - - ℃ began to work, so to eliminate the discharge of steam, able to work under the condition of standard pressure stability. Wax components type hydrophobic pneumatic valve under fixed temperature. Thermal type hydrophobic pneumatic valve work basic has nothing to do with temperature. The workability

ventilation thermostat hydrophobic pneumatic valve for pneumatic valve open state, when at the beginning of the ventilation air heating time shorter.
thermal type hydrophobic pneumatic valve for pneumatic valve closed state at the beginning of ventilation, although improved through design micro slit, but ventilation heating time is longer.
