Prescor valve TP M 3/4 x 3/4-7bar
The valve opens the outlet on reaching the settings for:
Temperature: the thermostat compound inside the temperature sensor, submerged in the hot water storage heater, expands as the temperature increases. This expansion causes a thrust pin to move and act on the obturator, opening the valve
Pressure: The obturator, opposed by a set spring, raises on reaching the pressure setting and opens the outlet completely. The pressure setting is chosen according to the maximum permissible pressure in the system.
As the temperature and pressure decrease, the opposite action occurs with the valve subsequently reclosing within the set tolerances.
Opening temperature: 89 ºC / 96 ºC.
Minimum/Maximum working temperature: -10 °C / 120 °C.
Peak load: 140 °C.
