Product classification of BESA safety valves in Italy:

2) Direct load safety valve .A directly acting machineMechanical load ，Like a heavy hammer 、Use a lever, heavy hammer, or spring to overcome it Safety valve for the force generated by the pressure of the medium under the valve disc.

3) Safety valve with power assist device .This safety valve is assisted by a power assist device ，Can operate below the normal opening pressure Activate under force .Even if the auxiliary device fails ，This type of safety valveStill able to meet the standard requirements.

4) Safety valve with supplementary load .This safety valve maintains an enhanced pressure at its inlet until it reaches the opening pressure Sealed pressure .This additional force（ Supplementary load） Can be provided by external energy sources ，And when the safety valve reaches the open positionReliable starting pressure should be applied Release the ground .Its size should be set as follows ，Assuming that the additional force has not been released ，The safety valve can still operate at an import pressure not exceeding the national standard

Under the premise of the prescribed percentage of opening pressure, the rated displacement is achieved.

5) Pilot operated safety valve .A method of relying on discharging the medium from the pilot valveSafety valves driven or controlled by quality .The pilot valve itself should comply with Direct load safety valve that meets standard requirements.

6) Proportional safety valve .A method that covers the entire opening height range orProportionally open or close within a considerable range of opening heights Closed safety valve.

7) Fully open safety valve .A proportional opening only within a small opening height range ，Then it suddenly opened to the fully open position The safety valve .The opening height shall not be less than 1/4 runner diameter.

8) Micro opening safety valve .A direct acting safety valve for liquid media only .Open the height at 1/40 ~ 1/20 Within the diameter range of the flow channel.
