It is mainly used for various pressure containers, instrumentation devices and piping in petroleum, gas and chemical plants, and is used also, in particular, for the places that are impacted by back pressure, and other places where no fluid discharge to the outside of safety valve is permitted. It can be used for the places where spring can be eroded or transformed due to corrosion or temperature of fluid, too.
Product Features
1. It is a product designed and manufactured in accordance with the standard of KS B 6216, “Safety Valve for Steam and Gas”.
2. Its structure is made to the bellows of balanced structure and is not impacted by back pressure.
3. As discharged fluid is not discharged to the outside of main body of safety valve, it can be used for toxic gas or combustible gas.
4. Discharging capacity of this valve is higher than low and high lift type.
5. Its corrosion resistance is excellent as main material of the trim part is STS 316
