Flexi-Drive operates hard to reach valves

摘要

The Flexi-Drive from Smith Flow Control is a cable-driven remote operator for valves in inaccessible or hazardous locations.It can transmit drive to valves as far as 60m(200ft)away,accommodating 540 degrees of bends in he cable run.The Flexi-Drive consists of three elements:an operator station(with a geared handwheel and mounting facility),a valve station actuator and a unique,patented'continuous loop'helix drive cable.Due to the properties of the strong,flexible steel cable,turning the handwheel of the operator station simultaneously operates the valve actuator.The cable allows high valve operating torque to be transferred through tunnels,walls,bulkheads,sewers,floors or any other obstacles between the handwheel and the valve.Suitable for any size or type of valve,regardless of torque or turn requirements,the Flexi-Drive is available in a range of reduction ratios,including 4:1,2:1 and 1:1,with no danger of delivering over-torque.
