******************************************************************
This animated 3D video shows how a pneumatic control valve works. Pneumatically controlled valves are those that actuate when air pressure is applied or removed. You will learn how the valve works, its main components and the different types of valve actuator.

▶️The 3D animation uses a straight flow (z-type) globe valve as an example. The valve is closed when air pressure is applied and opened when the air pressure is drained.
Valve components mentioned in the video include:
Disc / Lid
Stem
Seat
Diaphragm
Pneumatic Actuator
Body
Bonnet
Position Indicator
The different types of actuator mentioned in the video are:
Pneumatic / Air
Hydraulic / Liquid
Mechanical / Hand
Electrical / Motor
The concept of ‘fail safe’ is discussed. The fail-safe design means that a valve will turn to a pre-defined position upon loss of power. This position is designed to be ‘safe’ i.e. a position that will not cause a dangerous situation should the valve lose power.

Good Day! I am working with this type of valve on a chemical/product oil tanker. It was installed on steam line going to heater used for heating water during washing of cargo tanks. Regarding main problem with troubleshooting during loss of air, we had installed double manual valves before pneumatic valve and one after pneumatic valve. Control of temperature was possible with a thermostat that regulated air pressure on pneumatic valve. I can tell you that system worked for 16 years on that ship with proper maintenance and still in good shape. Thank you for your great work!

Nice video but I have seen a lot of pneumatic actuators working with throttling control valves. In fact most of them use diaphragm pneumatic actuator. If you want to be accurate, positioner are used. Please clarify (minute 7:45)

What is the fluid flow pressure?! I actually have a question for u. In case the fluid flow pressure is 5 bar. We have only 3 bar to activate the pneumatic valve then it is possible for the activation?! Expecting ur detailed explanation. Thank u in advance

Excellent video! At the end of the video you say that peumatic valves are used for on/off purposes only, from my experience, they are used for throttling , all pneumatic actuated valves I have experienced are used for throttling, so I need to clarify that point, which is the reference for that?

If oressure of the fluid in line is more than 7 kg per sq cm as u described for air, will the valve get opened??...how do we make and keep than it closed if if pressure of fluid handled is more than air pressure

Is it possible to remove the spring and use only the pressure of the fluid to control the valve?

@mtg1074 5 жыл бұрын

It is easier, simpler and more cost-effective to use the spring. But it is possible to remove it and replace it with air/oil pressure.

Amazing video! Where does the air come from? Is it atmospheric air available in the room? How does the air gets compressed?

An electrically driven pneumatic compressor provides the air which engineers call "instrument air".

@1Sumalani 2 жыл бұрын

Dear could you please answer my question. How small pressure in the pneumatic actuator .2-1bar is controlling the process fluid/steam pressure which is very high e.g 40 bar. Is it because of the area? Or what? Plz explain. How the force acting on diaphragm will overcome the force in fluid and spring force?

The globe valve gets it's name from the body shape of the earliest globe valves ever made, which had in fact a globe shaped plug and body.

@mtg1074 5 жыл бұрын

I'm sorry but the ending bits are entirely misrepresented! In the real world, globe valves with pneumatic actuators are solely used for throttling applications and seldom used for on/off services! And I've never seen any globe valves being used for isolation applications in Oil & Gas services! With the appliance of a positioner and I/P converter, you can use any type of Analogue or digital electronic signal to whatever air pressure supply you need for the valve (usually 3~15 psi).

There is an ISA standard for globe valve leakage classes. And none of those classes match the performance of even the lowest classes of an API 6D double block & bleed ball valve.
