2. Valve actuator - Wikipedia

   en.wikipedia.org/wiki/Valve_actuator

   These types of valves include globe valves, rising stem ball valves, control valves and gate valves. [2] The two main types of linear actuators are diaphragm and piston. Diaphragm actuators are made out of a round piece of rubber and squeezed around its edges between two side of a cylinder or chamber that allows air pressure to enter either ...

3. Ball valve - Wikipedia

   en.wikipedia.org/wiki/Ball_valve

   High-pressure ball valves are often used in hydraulic systems, so they are also known as hydraulic ball valves. Ball valves in sizes up to 2 inches (51 mm) generally come in a single piece, two or three-piece designs. One-piece ball valves are almost always reduced bore, are relatively inexpensive, and are generally replaced instead of repaired.

4. Control valve - Wikipedia

   en.wikipedia.org/wiki/Control_valve

   Valve actuator – which moves the valve's modulating element, such as ball or butterfly. Valve positioner – which ensures the valve has reached the desired degree of opening. This overcomes the problems of friction and wear. Valve body – in which the modulating element, a plug, globe, ball or butterfly, is contained.

5. Solenoid valve - Wikipedia

   en.wikipedia.org/wiki/Solenoid_valve

   Ordinary valves can have many ports and fluid paths. A 2-way valve, for example, has 2 ports; if the valve is open, then the two ports are connected and fluid may flow between the ports; if the valve is closed, then ports are isolated. If the valve is open when the solenoid is not energized, then the valve is termed normally open (N.O.).

7. Flow control valve - Wikipedia

   en.wikipedia.org/wiki/Flow_control_valve

   Control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as ...
