Oilfield Valves & Instruments Description: 10 Common Types ofValvesEvery Oil and Gas Engineer Should Know AboutValvesare essential parts of any piping system used to control the flow and pressure of contents, whether that is oil, gas, liquid, or vapors.Here is our list of 10 of the most commonly used oil and gas valves in the industry and the reasons for their existence.ARV or ARC valvesAcronyms for ‘Automatic Recirculation Valve’ and ‘Automatic Recirculation Control’, these valves are multi-functional but has the primary purpose of ensuring that a pre-determined minimum flow is assured through centrifugal pump at all times.As centrifugal pumps consistently suffer from being over heated, its important to keep the minimum flow otherwise dry valves means permanent damage.Ball valvesA ball valve is a quarter-turn rotational motion valve that used a ball-shaped disk to control a flow. If the valve is opened, the holes in the ball stay in line with the body inlet allowing contents to pass.The balls are generally made out of several metallics whilst the seats are made from soft materials like Teflon. The combination of materials means the ball valve can operate at temperatures as low as -200 deg C and as high as 500 deg C.Mainly used for air, gases and liquids, ball valves are quick to turn on and off and have a tight sealing with low torque. The only downside to these valves are the lack of throttling properties available. View Full Blog Content...
