Butterfly Valve Engineering Data

Torque Figures

The torque figures provided represent the required torque to open and re-seat the valve. The figures provided are based upon water and other lubricating fluids, and include a factor of safety.

For gases, non-lubricating media and dry powders increase the torque figures by 1.3 Eurotorc offer a valve with either a 3 Bar or 6 Bar reduced diameter disc. This reduces the friction and torque, decreasing actuation sizes and extending Seat life.
