valve location a problem
……no problem
Smith Flow Control have now developed this unique cable drive system that has revolutionised the placement of valves and the particular difficulty in operating them in confined spaces.
In a hazardous area, below water, in a confined space, in a pit, where noxious fugitive emissions prevail or just plain out of reach,  is the answer.
is a very versatile product consisting of two stations, joined by a unique patented linear drive cable. This equipment enables valves and other wheel-operated devices in remote, hard to reach or hazardous locations to be operated easily from a conveniently located handwheel.
|
|
Developed to operate valves in inaccessible locations, can be applied to any conventional wheel-operated valve/device, in oil, gas and chemical processing plants, or any other industrial application. It is suitable for underwater use and will function reliably in all climatic conditions.
The cable system can deliver adequate torque output for most manual valve situations and can transmit drive to a valve up to 60 metres from the operator station. The flexible cable system facilitates up to 540 degree of bends in a cable run. |

| 1. Operator Station Actuator |
Operator Station are available in a variety of different gear ratios, providing a wide range of torque capabilities. A helically wound steel cable has a pitch the same as that of cable gear. The precision gear-cable interface provides a positive force to the helix cable, which travels through th flexible conduit to the valve station actuator.
- a unique valve cable drive system for the oil and gas, petrochemicals, marine, water, and power industries.
