Hi, welcome back to another Crane Engineering product review, today I'm here with fluid process engineer, Chris Johnson and he's here to introduce a brand new line for us; Rieger valves.
Thanks Sara, my name is Chris Johnson, I've been with Crane Engineering for about 3 year as a fluid process engineer, but before that I used to work with a sanitary pump and valve manufacturer. What we have here today is a brand of valves that I've really liked to work with in the past few years, is Rieger valves. Rieger is a company based out of Germany that provides a full line of linear valves. When I say linear valves I mean valves that move up and down inside of the process, not like a ball valve or a butterfly valve, more formally known as quarter-turn. They build valves from something like this, which is an N2, which is a PMO mix-proof valve. Care to know more, we can talk about that in a lot more details. To linear ones that are just single seat. Also have sample valves down to just quarter inch.
So, which industries are tending to use these valves more than others?
Generally with a valve of this nature, we would be using it in an industry where they are very concerned about cleanability. More or less, food and beverage industry. Sometimes a high purity type of ingredient manufacturers as well. Anywhere where cleaning is really important.
So, there's a lot of sanitary valves on the market. What is it that makes Rieger valves different or more unique than some of the other ones that are out there?
Some of the biggest features are from a maintenance standpoint. Not only are these valves made from a solid bar stock, but they use o-rings for sealing so maintenance is a breeze. Literally popping off different parts and pieces, servicing the valves without air makes repair easy for anybody in maintenance. Plus, it's an engineer's friend because they're easy to work with and they meet all of the requirements that are needed.
So, obviously this is good for a lot sanitary applications but there's going to be times when this isn't going to work out and you're going to want to go with something else. When would these not be right for your process?
You are right. A lot of times we could get away with a sanitary butterfly valve or a ball valve that meets the requirements but is not 3A or EHEDGE approved. Generally we use these for processes that are CIPed. If it's a COP process, we can always take a different valve and take it apart, it'd be less expensive.
