Unlike check valve that operate in only one way, the versatility in control valves allows them to be used in many types of applications, most often in the oil and gas industry. The most common type of control valves are:

Sliding Stem Globe Control Valves – This valve uses a movable disk and a stationary ring seat housed in a generally round body that regulates liquid flow in a pipeline. The stem in the valve is either threaded for manual valves or smooth for actuator controlled valves and acts as a connector to transmit force. Sliding stem valves are often offered as angle-pattern, three-way valves, or straight pattern, aka globe. These control valves often meet a range of ANSI Class requirements including flow characteristics, pressure-temperature ratings, size, shutoff capability, and temperature compatibility.

Angle Control Valves – These valves are also used in applications involving liquids in high pressure or drop conditions. As their name suggests, they operate at an angle with the inlet allowing liquid to flow into the chamber and through the outlet based on user instructions.
