MADE IN USA. The EVKeg is a safe, durable polyethylene beer keg (150 PSI capability) that has the unique features of using an ozone sanitized liner that is replaced with every fill eliminating the need for keg cleaning, and a self setting pressure relief valve that prevents the keg from accidental over pressurization.
Orifices are generally used as measuring and hydraulic control devices. Orifice. hydraulics control the function of many submerged inlet - free outlet culverts, primary spillways in detention facilities, manholes in conduit flow, and in storm drain.
Another thing to consider when applying an orifice is that the size of orifice is not always directly related to the size of the valves. Rather, the orifice is sized to the application. While there really is no way to know which size orifice will give you the best performance without performing some tests, one thing to keep in mind is this: the smaller the orifice the more susceptible it will be to contamination.
