The proprietary system includes TRV module, actuator, and isolation valve. It provides an accurate high-flow-capacity relief valve or shutdown device to prevent accidents and/or downtime. The non-closing valves do not rely on prediction of material failures like rupture discs, shear pins, or buckling pin devices. No external power is required for operation.
model 6620 shutdown version is also offered to shut off when the valve reaches set pressure or is triggered remotely.
