SDA-180 is a safety device which intercept gas flow whenever the pressure under monitoring reaches a re-set limits or whenever manually required by operator on site or through remote control(optional Device) SDA-180 is a reliable safety shut off valve with self operated actuation and manual resetting. It is ideal product for transmission networks , large industrial and any high profile applications such as Pressure regulating gas stations.SDA-180 is suitable for natural gas or any non-corrosive gaseous media. It uses gas under service ( flowing in pipeline ) as a feeding fluid for actuation. Its modulating design allows an easy maintenance and changing main parts without removing the body from the pipeline.
