Over Pressurisation Device OPD SILSAVE From the day the company was founded in 1956 it was decided that our business should be built on the premise of creating solutions that far outweigh expectations. Over recent years users of Regulators and Filter Regulators have become aware of the consequences of the failure in service of such equipment including the potential for damage to pressure sensitive instruments, actuators and process valves which may compromise critical ESD systems, resulting in unscheduled production shutdowns and expensive repairs. We have always had a strong, experienced and...

Over Pressurisation Device OPD SILSAVE Development Failures of pressure regulators can result in the over pressurisation of the downstream line, as the self-relieving capacity of the regulator is insufficient to cope with major failures. Usually a relief valve of sufficient capacity is fitted into the system to hold the pressure down to an acceptable level. However a relief valve flow is sized on a pressure differential between set pressure and over pressure, usually 10%. Thus on a set pressure of 4.5 barg a pressure rise to 4.95 barg would have to flow sufficiently to hold the pressure at 4.95...

Over Pressurisation Device OPD SILSAVE Over Pressure Device Operating Poppet Valve 0.2 Litre Isolation Valve ¼ Turn Ball Valve Overpressure Valve Performance Characteristics • Response times are dependant upon the actual pressures within the system at the point of failure; all times stated within the specification section are maximums taken at the lowest extreme of the pressure range (worst case). The magnitude of any pressure spikes exceeding the trip pressure which occur during deployment of the valve are dependant upon the system downstream volume; a larger system volume decreases the likelihood...

Over Pressurisation Device Larger actuator test results. volume of 3 Litres. Trigger Test- Blue = Actuator Pressure (Bar) The graph above is an overpressure test result with a larger 3 litre reservoirto simulate the actuator. An overpressure signal is allowing the 11 barg supply pressure to bypass the regulator, simulating a ruptured diaphragm. The response time of the device is measured as the time between the pressure within the device reaching the trip pressure and the actuator pressure returning to below the regulated pressure (see dashed lines on graph & right hand column of table). Note...
