25000 Series Lo-T Butterfly Control Valve
 |
The patented shape of the LO-TTM vane controls the flow by subdividing it into separate streams which are then forced into rapid deceleration of directional change in the downstream body cavity, for a most effective throttling action, diminishing pressure recovery that is mainly responsible for cavitation and noise. This separation is especially effective within the first 50% of travel where the highest pressure drop is encountered.
Angularly offset disk halves combine opposed dynamic torque characteristics, thereby providing a drastic overall torque reduction. This torque reduction allows for a substantial increase in the pressure drop capability of the
valve without requiring oversize actuators.
