When I started at Valvtechnologies I was thinking this is going to be easy, there is nothing to a valve. I found out that there is so much to know it is quite overwhelming. Materials is very important depending on temperature range, hardness depending on refinery or mining conditions. Also chemicals that are being exposed to makes a huge condition for the seals which sometimes have to be custom designed just for a few valves. Then there is torque rating which dictates which actuator rating is needed depending on pressures being induced to valve. There are hydraulic, manual, electric, and pneumatic actuators from lots of different vendors with different bolting patterns and individual drive sleeves have to be designed for every application as well as mounting brackets. All of that is the basics, then there is the machining aspect of all the components which I won't go into detail, there is much to know and learn. there is also the aspect between forging and casting which can change the designs dramatically. I learned more then I could ever have expected from working at Valvtechnologies. It was quite a educational career choice. Unfortunately it is a job that revolves around sales. If they aren't selling then we aren't designing.
Close to home, good people
