The ECON bellows shut-off valve made of steel is 100% leak-free to the environment thanks to the double stainless steel bellows. This means it is also emission-free, making it particularly suitable for applications in the chemical and petrochemical industries and for use with high-temperature media such as steam and thermal oil.
Thanks to the stainless steel bellows, the valve is not only leak-free but also maintenance-free, as there is no stuffing box seal to be tightened. The additional stuffing box along the spindle is only used as a reserve.
As of DN200, the ECON bellows shut-off valve is supplied as standard with a pressure-relieving valve.

Application

General industry, power stations, exhaust gas purification, thermal oil systems, steam systems, heating systems, vacuum systems.
