PQ relief valve |
Features In pressure transmission system,pressure relief valve is used to limit the maxiumum pressure in return circuit,in case the pneumatic device,equipment and pipeline cannot work normally.When the pressure exceed the maxiumum pressure ,relief valve begin to exhaust automatically until the pressure below the MAX pressure, when the pressure is lower than max, the valve close automatically. |
