you actually answered your own question, there are many different speed control devices for pneumatics,since there so many applications finding the correct device may take some research. make sure that the device is suitable for the high pressure side of the system,basically a speed control device is a throttling valve
The wrod pneumatic deals with the pressure and air control ....now according to newtons law...f=ma; we can add a relay to pneumatic, a relay is a electromagnetic switch which connects to circuit and control the flow elctricity....in the circuit.....thus , by reading the above theory we can estimate that what pneumatic relay is exactly.... no claps for me,,,,,, thank u..
Current will flow as long as there is a difference of potential (a voltage) and a path for current to flow. So no power-control device is required for current flow but yes it will flow with a power control decive.
It is a variable resistance device which control the flow of current
Pneumatic process control valves are used in process industries to control the flow of fluid by using pneumatic actuators. It requires 4.5 to 6 Kg/sq. cm of pressure to operate the valve. Control room sends electrical signals of 4-20 ma to field where I/P converter converts these electrical signals into pneumatic signals. Actuators use these signals to operate the valve. Actuators moves the stem up and down depending upon input signals and control the valve opening. 4ma- 0% opening 8ma- 25% opening 12ma- 50% opening 16ma- 75% opening 20ma- 100% opening
An active device is any type of circuit component with the ability to electrically control electron flow (electricity controlling electricity). In order for a circuit to be properly called electronic, it must contain at least one active device
The speed of a pneumatic motor is controlled by regulating the flow of intake air with a proportional control valve Paul Berbakov
The speed is varied by throttling the air flow into the motor.
When a pneumatic cylinder chamber is filled with pressurized air and the air-chamber on the other side of the piston is metered-out by a flow control, the movement or speed of the cylinder is more consistent than to meter-in the pressurized air.
If you are talking about a pneumatic solenoid valve the function of it is to control the air in and out flow in a pneumatic actuator.
Air flow
The device which control the speed of Turbine is Governor. The Governing system sense the speed of shaft & regulate the Fuel/ Motive fluid flow to the Turbine to maintain the set shaft speed.

A: Electricity is not a device but rather a fiscal flow of electrons
Resistors are used to control current flow.
Specialityvalve is one of the top-most Pneumatic Globe control valve manufacturer in India. They are mainly used in industries to handle or regulate water, air, steam, gas, oil and other fluids in processes having wide flow range requirements. Today, the market demand for installation and use of pneumatic control valves is huge, not only in industries but also in daily life. Pneumatic Globe Control Valve allows precise control of flow rates and speed of the system. It is a type of Globe valve that allow control of flow rate and speed in the system. Industries Oil and Gas Chemical Petrochemical Refineries Advantages Good ability to switch Simple structure, convenient production and maintenance Good ability for flow regulation Stroke for valve opening and closing is greater than Gate Valve Description Body material- Brass, Bronze, Titanium, Cast Iron, Cast Steel (A216 WCB, WCC, LCB, LCC, WWC6, WC9, CF8, CF8M), Cast Ductile Iron Class- 150 to 2500 PN10 to PN450 Size- ½” to 80” End Connection- Buttweld, socket weld, flanged, threaded Operation- Pneumatic actuated Specialityvalve is one of the best Pneumatic Globe control valve manufacturer in India
