The primary purpose of a valve is to direct the flow of fluids by starting, stopping, and throttling (regulating) to make modern processes possible. Valves are designed to withstand pressure, temperature and flow, and can be found in homes and industry across the world. Process operators classify valves by flow control elements, function and operating conditions (such as pressure, flow or temperature). The more common valves found in oil refineries and chemical plants are as follows:

Ball	Starting and stopping a flow. Quick opening and closing. Not good at regulating or throttling.
Plug	Starting and stopping a flow. Quick opening and closing. Not good at regulating or throttling.
Gate	Starting and stopping a flow. Not good at regulating or throttling.
Globe	Regulating or throttling a flow.
Check	Used to prevent reverse flow (back flow).
Needle	Regulating or throttling a flow.
Butterfly	Regulating or throttling a flow.
Safety	Designed to open quickly to excess gas or vapor pressure in side a vessel.
Relief	Designed to open slowly to excess pressurized liquid.
