When these valves reach a certain pre-calibrated vacuum degree, they introduce atmospheric air into the circuit to prevent the increase of the set value and to keep it constant. They can be used as regulators only on circuits having only one vacuum pump and only one use (or more uses but all working at the same vacuum degree). In most cases, they are used as safety valves on non-commissioned tanks or containers at high levels of vacuum and on vacuum cup lifting systems. The level of vacuum is adjusted by rotating the knurled bush in both directions. The fine thread with which the valve is provided ensures a very accurate calibration. The temperature values within which the valves can operate go from -20 °C to +120 °C. Items Available: 040110 040210 040310 040410 040510 040110I 040210I 040310I 040410I 040510I
