HBC 975 HBC 975 This is a safety device (SAV) which quickly intercepts gas flow when the pressure it is monitoring reaches a pre-set limit due to any anomaly in the system, or when required by the operator at installation point or from remote point.
VS/AM 65 VS/AM 65 The VS/AM 65 relief valve is a safety device (SBV) which vents gas when the system pressure exceeds the set value due to temporary events such as expansion due to rise in gas temperature or downstream pressure shocks caused by sudden changes of flow rate etc.
