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. |
