#79 -- A Guide to Loosening Locked-Up Valves with a Valve Wheel Wrench

Posted by Jason Hugo and Anna Hartenbach on 10/19/2017 to Valves
Opening a valve, in theory, isn’t a challenging task. However, opening a wheel operated valve that is stuck can be extremely tricky and frustrating. There is no amount of twisting, turning, pulling that seems to make a difference with a locked-up valve.

So what do you do when you run across an older system, with visible signs of aging, and rusted or stuck valves? How do you loosen stubborn valves without “throwing a wrench” into the whole job (pun intended)?

Our solution: A valve wrench. This tool is indispensable in the field, with its handy ability to open even the most stubborn wheel valves.

In this article, we’re going to teach you how to use a valve wheel wrench to loosen a difficult valve. We’ll take a look at the valve wheel wrench itself to get a better understanding of what it is and what sets it apart from other wrenches.

What is a valve wrench?

A valve wheel wrench is a specially designed wrench used to grip the wheel of a valve to support efforts to open and close valves. They are particularly useful when opening a valve that has been shut too tight, is rusted shut, or stuck.

Valve wheel wrenches come in a variety of shapes and sizes. Most have a handle and a head. In some designs, the head is in the shape of a “C” and in other designs the top of the “C” is more prominent, while the bottom of the “C” is less obvious – these designs usually have another semi-hook or “seat” beside them to provide a better grip. Additionally, some are double-headed, which gives the versatility of two sizes on the same wrench. While valve wrenches can be made of ductile iron, aluminum-magnesium, steel, or alloy steel; we highly recommend aluminum as it features a great weight to functionality ratio.

How do I use a valve wheel wrench to loosen a stuck valve?

To use a valve wheel wrench to loosen a stuck valve, use the “C” shape or hooked end to grasp the valve wheel rim, apply pressure, and turn the wheel.

Use a Valve Wheel Wrench to Loosen a Stuck Valve

That’s the short answer, but the longer answer goes a bit deeper. To understand it better, let’s delve into the laws of physics.

The valve wheel wrench is essentially a beam or solid rod with a fulcrum on the end. You are applying the input force to the valve wheel with the wrench by grasping, gripping, applying load pressure, and turning. The result comes from the output force generating motion for the valve wheel.

Using a valve wheel wrench to loosen a stuck valve provides a simple solution to a sticky problem. Just like the ancient Greek mathematician Archimedes discovered, using a lever to apply pressure to one end results in torque at the other end and produces a greater result than a man can reasonably accomplish on his own.

A valve wheel wrench has many practical applications within the fire protection industry. It can be used on many types of valves, including: grooved, wafer, and flanged butterfly valves; gate valves; and OS&Y valves. Aside from the fire protection industry, this wrench can serve as a handy ally for oil rigs, ships, Navy vessels, steam boats or trains, steam factories, power plants, water valves at treatment plants, dairy farms, universities, and water and theme parks. Pretty much anywhere with a valve wheel can benefit from a valve wheel wrench.
