    In the heating system, there is a large demand for safety valves for which they provide a lot of security for the entire system. Therefore, it is necessary to maintain them in daily life. When the pressure value exceeds the specified parameters, the valve will open automatically in the water supply ...
  • Damage of the Abnormal Pressure Rise – Gate Valve
    Posted: 08/05/2015 14:18:35  Hits: 304
    Abnormal pressure rise of gate valves may happen in many applications and the reason can be classified into this two aspects: the system media changed from cold into hot after the boot; the gate is off in the cold state and on in hot state. Therefore, if there is no action to be taken to protec...
