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.
A piston is attached to the end of the piston rod and works against hydraulic fluid in the pressure tube. As the suspension travels up and down, the hydraulic fluid is forced through tiny holes, called orifices, inside the piston. However, these orifices let only a small amount of fluid through the piston.
