Valve Actuator remotely operates valves in harsh conditions.
Press Release Summary:
Flexi-Drive consists of 3 elements: operator station comprised of geared handwheel and mounting facility; valve station actuator; and drive cable that links both. Cable transmits torque in excess of 280 lb-ft up to 200 ft away, accommodating 540° of bends in cable run. Designed to withstand high impact shock, sinusoidal vibration, and open flame conditions, unit can be used down to 50 ft underwater and in temperatures from -65 to +400°F.
Original Press Release:
Remote Valve Operation with Flexi-Drive
(Erlanger, KY) - New from Smith Flow Control is the Flexi-Drive, a versatile device for the remote operation of valves in hard to reach or hazardous locations. It consists of three elements: an operator station (comprising a geared handwheel and mounting facility), a valve station actuator, and a unique, patented drive cable linking the two. Due to the properties of the flexible steel cable, turning the handwheel of the operator station simultaneously operates the valve actuator.
The cable can transmit torque in excess of 280 ft-lbs up to 200ft (60 meters) away, accommodating 540 degrees of bends in the cable run. This allows it to be passed around and through walls, bulkheads, floors, tunnels and any other obstacles to reach the valve. Suitable for use with any size or type of valve regardless of turn requirements, the Flexi-Drive can generate torque in overall ratios, including 4:1, 2:1 and 1:1, with no danger of over-torquing.
With a service life in excess of 20,000 valve cycles, the Flexi-Drive provides uninterrupted operation for the life of any valve. It is completely sealed and permanently lubricated, never requiring maintenance, thereby eliminating costly service requirements. A further advantage is that the gearing system can be 'piggy-backed', allowing more than one valve to be operated from a single operator station.
Smith Flow Control understands that difficult, hard to reach valves are often located in unusually harsh environments. The Flexi-Drive system is therefore designed to withstand the most severe conditions, including high impact shock, sinusoidal vibration and open flame. It can be used down to 50 ft (15m) underwater and in temperatures ranging from -65° to +400° Fahrenheit (-54° to +200° Celsius) dependent on construction material.
