With a unique "Cosine-Curve" structure and raised center seatring, TOMOE has developed the world's first butterfly valve with torque adjustment. The valve operating torque is controlled in relation to the valve working pressure, enabling the actuators to be reduced in size and the effect of friction on mating surfaces being kept to a minimum.
A wide range of seat, disc and body materials are available to suit most fluid conditions. | | | |
