Here is a light hearted history and trivia on the ball valve. Read it and you will never take your natural gas or electricity for granted again, ok so maybe you will...

Ball Valve mystery?

The humble ball valve has a checkered history and somewhat murky origins. It may not be cloak and dagger stuff, but it's not without mystery... Take a look around to see where the ball valve is indispensable. For example, the ball valve is crucial to the petroleum industry, water, electric power, chemical, paper, pharmaceuticals, food, steel and other fields. If it seems we could not get a long without the ball valve, it's probably true! Given the importance of the ball valve today, it's a mystery why it took so long to invent.

Ball Valve history does not go back to ancient Greece or the American revolution or does it? The modern ball vale was invented in 1967 or about 1957 according to different sources. Who cares when the ball valve was invented? Besides the patented owner, probably not many people. Still the ball valve was major advancement over plug valves used in the 20th century. The earliest ball valves were commercially available around 1967. For ancient parallels, the ruins of Pompeii turned up a bronze tapered plug quarter turn valve that resembles to the ball valve today. How's that for a ball valve mystery?

Ball Valve Birth Pains

Ball Valve researchers point to a spherical ball-type valve patented in 1871 led to the invention of today's ball valve. This ball valve was an all brass valve- brass ball and brass seats. Apparently this ball valve didn't storm the market and was not mentioned in valve catalogs of the late 1800's While today's ball valve is quite a recent invention, the idea for this ball valve has been around about 125 years. The first resilient seated ball valve patent was issued in April,1945. Legend has it the company's marketing department could not envision a use for the valve and it was not manufactured. Oh well, that's the way the ball valve bounces...Given the huge reliance on the ball valve today, it's a mystery why it took so long for people to invent and use the ball valve.

Valve Marking: What Are Your Options?

Valve marking is an important part of your facility's pipe safety. Valve marking enables employees and visitors to identify which valves are associated with specific pipes. This is important if a pipe has a leak, is being repaired or needs to be emptied, for example.

 

There are various products you can use for valve marking. One of the best choices is a metal valve tag. Metal valve tags are durable, and therefore a great way to label pipes and other equipment in harsh environments.

 

• Aluminum Valve Tags

Aluminum valve tags are tough and durable for repeated use. These tags do not bend and will not rust, even if they are scratched. Aluminum tags can also withstand temperatures of 1500° F. And, if you want to color code your valves, some companies sell color-coded aluminum valve tags that are precision engraved to ensure the wording won't wear off.

 

• Brass Valve Tags

Brass valve tags are a more economical valve marking option. Similar to aluminum tags, brass valve tags will not bend or break. But, they can only withstand temperatures of 1200° F.

 

• Stainless Steel Valve Tags

Stainless steel valve tags are rust resistant and can stand up to highly corrosive environments or extreme weather conditions. These tags can withstand extreme temperature of 2700° F.

 

Plastic valve tags are also a viable option for valve marking. Plastic valve tags can be an economical and easy-to-use option for valve and machine marking. Unlike metal tags, plastic valve tags offer you the option to write right on them, versus spending extra money on engraving.

 

• Self-Fastening Tags

Self-fastening tags allow placement of a tag on valves and equipment without the need for fasteners or tools. Self-fastening tags are flexible, yet durable for high performance. They also resist dirt, grease and moisture. These tags are available in stock legends such as "Do not close this valve" or OSHA-required headers. They even come blank so you can choose your own message.

 

• Economy Plastic Tags

Economy plastic tags are made of thin plastic that can be attached to valves or machines with virtually any type of fastener. Economy plastic tags are not overly durable, so they may not be the best choice for making valves exposed to harsh conditions.

 

• Heavy-Duty Plastic Tags

Heavy-duty plastic tags are made of thicker plastic so they can withstand tougher use. Heavy-duty plastic tags are a more durable, tear-proof valve tag as compared to economy plastic tags. Like most plastic valve tags, you can have them custom worded or simply write right on them.

 

• Write on Tags

Most plastic valve tags can be easily written on for quick valve marking. Some write-on tags come pre-numbered with space to write a personalized label, while others come completely blank for full customization.

 

Which will you choose for your next valve marking project?
