Valves
Valves are essential parts of any piping system used to control the flow and pressure of the 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.
Ball valves
A ball valve is a quarter-turn rotational motion valve that used a ball-shaped disk to control a flow. 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.
Butterfly valves
A quarter-turn rotational motion valve, the butterfly valves are used to stop, start and regulate flow. Easy and fast to open, the valve usually comes equipped with a gearbox where the hand wheel with gear is connected to their stem. This simplifies the operation of the valve, but at the expense of speed.
Gate valves
Gate valves are primarily designed to start or stop a flow when a straight line flow of fluid and minimum flow restriction are needed. In service, these valves are pretty much kept either fully open, or fully closed. When turned open, the disc of the gate is completely removed, allowing contents to pass.
Globe valves
Typically used for cooling water systems, transporting fuel oil and turbine lube oil systems, a globe valve is a linear motion valve used to stop, start and regulate flow. Conventionally used for isolation and throttling services, the globe has become the world's most common types of valves. With a good shot off ability, available on tee, way and angle patterns and easy to machine the valve seats - it's easy to see why they are so popular.
