Sherwood Valves Are Known The World Over

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.

The butterfly valve has a closing device that looks very much like a disc. They are used for quick shut off and are much lower in cost compared to the other larger valves. They are much lighter which means less support needed to hold them up. It is only a metal disc that is fixed to a rod and it does quarter turns when shutting off or opening the flow.

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 main part of the typical valve is the bonnet and body. The body is the out casing and surrounds the inside parts. The bonnet is the part of the pipe which the stem passes through and is a guide and seal. The bonnet also acts as a cover and is partly permanently screwed into the body. When getting made the internal parts are put into the body and the bonnet is later attached keeping everything in its proper place.

The 6074 series is used for all medical applications as well as ecological monitoring. These are available in several seat material configurations and have an improved flow which helps in dropping vents as well as cleanse times. The hand wheels are made of aluminium and are available in either blue, red as well as rubber coated or chrome plated.

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.
