Auto Shut-off Valve (ASV1)

Definitive for extended operation of SWAS depends upon the principle of sample conditioning components for which accurate pressure flow and temperature control is most essential. Excessively hot samples can cause damage to expensive and sensitive sample conditioning components of the process analyzer. The auto shutoff valve is widely used in Steam Water Analysis Systems ( SWAS ) in power plants. The AXIS provides a very reliable Auto shut-off valve also called ASV1. This is functioning directly exposed to the sample media via the thermal expansion principle using wetted media. ASV1 is a self-reliant, fully mechanical device that required no external source of electricity or pneumatic or hydraulic. It is developed to sustend the sample temperature up to 50°C ± 2°C. After shutting off ASV1, it must be reopened by pressing the manual reset button which ensures the no flow resumes and the safety of the upset component has been amended.
