Emergency Shut Down Valve

 

The Emergency Shutdown Valve (ESDV) controls process media flow and is responsible for isolating the supply of hazardous gasses and fluids within the pipeline in the event of an emergency. As a result, these valves provide more reliable performance than standard on-off valves

Desuperheater

 

DV400-Series range of Valves was developed to provide a cost effective, reliable and easily maintained control valve capable of working in rigorous environments.The quick change trim option provides for easily accessible seat and trim components to minimise fitting and parts replacement times. Stem guided contoured trim in both balanced and non balanced configuration gives excellent rigidity and resistance to vibration and service wear.The valve is designed to accommodate other products within the DJC multi-hole multi stage and disk stack X[iks]-Trim.

These valves are for water or air service service where a drop-tight shut-off and double flanged flanged body are required 

 

Suitable for variety of liquids and gaseous media in water works, power plants, sewage plants, process industries, chemical and petrochemical plants etc. for tight shut-off and control. 

 

Ideally suited for isolating as well as throttling
