What is a Valve Gear Box?
A valve gear box gives a rotational torque driven from a manual input (handwheel) to turn a valve. In this case we are talking about ¼ turn valves (90 degree turn) such as ball or butterfly valves. The valve can be stopped anywhere in its rotation simply by stop turning the hand wheel. It comes with a visual indicator to see where the valve sits between its fully open and fully closed position.

How does a Valve Gear Box work?
The valve gear box works by a hand wheel input force turning a shaft which interfaces with a set of gears contained within a sealed case. These gears amplify the torque output and transmit this through a female drive in the bottom of the gear box case. This interfaces with the male drive on the valve turning the valve as the gear box moves.

How long will my Gear Box last?
This will depend upon the media and environment the gearbox is used in but ours are specifically built to a higher standard than most traditional gear boxes. Ours have a 316 Stainless Steel shaft which leads into a fusion bonded epoxy ductile iron body. This has an IP67 weather rating so is ideal for outside use. All fasteners are 316 Stainless Steel to reduce corrosion.

How do I install a Gear Box on a Valve?
The gear box will need to be interfaced with your valve taking into consideration three primary factories; the torque required to operate the valve, the mounting interface on both the valve and gear box and the drive sizes on the valve and gear box. For the torque it is common practice to take the torque required for the valve and add a 30% margin, this then needs to be matched to find the appropriate gear box. For the mounting interface you will need to check the ISO5211 details on the valve & actuator (eg. FO7 interface etc). If this does not fit or is not available on the valve a bracket and drive will need to be used. For the drive interface the male drive on the valve and the female drive on the gear box will need to be matched. These quite often are different and a drive sleeve is used to bridge the two.

What are typical uses of a Valve Gear Box?
These are mainly used on ball and butterfly valves but in reality can be used on anything that requires a 90 degree turn and can be interfaced.
-
How long will my Gear Box take to get to me?
This depends upon where you are based and the freight method chosen. If the express freight option is selected it is usually next day delivery to metropolitan areas in Australia for under 5kg. If free freight has been selected it will go by road freight which can be anywhere from 3 to 10 days depending upon your location. It usually averages 3 days.
