Sherwood Valves Have A Proven Record Of Offering Reliability

By Beryl Dalton


Some brands bring more than just features to the table. Sherwood Valves began in 1923 in New York, Buffalo. The next sixty odd years they earned a status of keeping pace with changing needs and requests of all their customers. In the middle 1980s, they amalgamated with Harsco Corporation which gave them better opportunities for technologic development as well as helping them financially.

Eleven years later they then merged with Taylor Wharton Gas Equipment and are still today a part of the Taylor Wharton LLC. Taylor Wharton is now updating their 2009 logo which has presented itself for more than eighty years of international brand fairness. The new one will still maintain their association to heritage and modern flare but now with culture included as well.

Their valves for dense gas applications are made in the United States and it includes the medical, chlorine and all specialty and semiconductor applications as well. These are made especially so that they exceed the safety levels for that specific cylinder. All of the pressure relief devises used are on file with the Bureau of Explosives.

A diaphragm valve has a body and supports either two or more ports. It was designed for industrial purposes but was changed so that it could be used in the bio-pharmaceutical industry as well. This needs to be able to withstand all sterilizing and sanitizing methods. They can be either computerized or manual depending on their use.

The 5074 series is explicitly made for all pure gas applications as well as purity gases, or even UHP mixtures. As it has a resistant pin this helps avert seat extrusion and the flow of its polymeric seat as well. Each one is available with a separate pressure relief apparatus which will protect it from getting damaged during replacement and transportation. They come in either pointed, straight thread as well as the international series any other ones will need to be requested.

Each valve has a port or passage that lets the fluid pass through. These are closed by discs that control the flow. There can be as many as twenty different ports and can be connected to other pipes via cement, flanges, glue, threading and compression fittings.

The disc that restricts flow through the valve can come in many different shapes. Depending on the type they can either move linearly or rotate on the stem or trunnion. The seat is connected to the disc and helps to form a leak proof seal. There can be either a hard or soft seat but all hard seats are known to leak. The soft seats are all made with softer materials depending on the functioning temperature.

Whichever kind that is needed, the folks over at Sherwood will ensure that their product is made to the highest standards and their engineering team is always working on improving and creating new products. They use the latest technology which enables them to lower costs and at the same time increase quality. All their personnel are friendly and will go out of their way to help new and existing customers.
