Rotex Double Offset Butterfly Valves are high-performance valves designed for reliable isolation and flow control in demanding industrial process applications.
The double offset design reduces contact and friction between the disc and seat during valve operation, helping minimize seat wear and provide dependable operation. The range covers sizes from 2" (DN50) to 24" (DN600) with wafer, lugged and flanged configurations.
A wide selection of body, disc and seat materials is available to suit different process media and operating conditions. The valves can be supplied with manual, pneumatic or electric operation together with gear operators, solenoid valves, limit switch boxes, positioners and air filter regulators as required.
