Econ® High Performance double eccentric butterfly valves

Econ®’s double offset design and patented floatable seat construction provides a reliable 100% bi-directional disc sealing. This unique construction meets the high demands of applications in which High Performance butterfly valves are being used. Econ® High Performance butterfly valves can be used for a maximum pressure up to 51 bar or a maximum temperature of 500°C. Econ® High Performance butterfly valves can therefore very well be used for applications, where rubber lined butterfly valves no longer can be used, due to their limited pressure and temperature range.
