Valve Wrenches, how do they work?
Have you ever tried to turn a valve wheel and couldn't get it to budge? Valve Wrench are engineered with basic physics to give an operator a more torque to help move subborn valves. They can be used in an unlimited number of applications and different facilities. The basic home owner with pool or irrigation systems, to operators working in any type of steam room, manufacturing facillity, chemical companies, and / or refineries too. Any place you can imagine an valve on a pipe is where a technician could use a valve wrench. Many of the refineries and chemical companies require that hand tools including valve wrenches be made of aluminum or even bronze in an effort to keep sparking to a minimum.
Did you know that valve wrenches come in a large variety of sizes, as small as 8 inches to as large as 48 inches, and weighting in at less than one pound to as much as 17-1/2 lbs. Any one can use the advantage of a valve wrench.
Archimedes famously said " give me a lever long enough & I can move the world" Here is a simple formula, and explanation on how and why a longer lever (valve Wrench) with the same amount of force can open a stuck valve.
Torque is defined as the moment of force. If force "F" is applied and the end of a lever (in our case a wrench) & "r" is the distance from the stuck vavle to the end of the wrench (the point of application) then Torque on the valve is given by T=r x F . Thus one can increase the torque by increasing the length of the lever (wrench) or increasing the force. The simple explanation is the longer the lever, the less force needed to losening the stuck valve.
