What is line blinding? The valve blinding is done to stop a process flow or to provide an obstruction in the line. It is done to prevent the release of combustible or toxic materials such as vapors or gases outside the pipeline. Most of the control valves are not capable to isolate total equipment so …

A pump can be described as a device that can transfer or raise the fluids, this device can also be used to achieve a constant flow rate or a constant pressure rate. The pump can add energy to the fluid this device is capable to convert fuel energy to water energy with the help of …
This type of valve would allow the flow in one direction and it would restrict the flow in the opposite direction. These valves are normally closed valves, in order to do a reverse flow a check valve is used. These valves are mostly placed between a cylinder and the directional control valve. The counterbalance valve …
The airlock unit is very useful in a control valve. This could provide the stay-put condition of the control valve in case of the air supply failure. The air pressure is blocked inside the diaphragm chamber of the actuator when the supply air pressure falls below the desired set value. A double-acting air lock relay …
A transmitter can be described as a transducer, which would convert a measurement variable into a transmission signal. These transmitters are inevitable in process industries, in the process industries the control instruments would be located away from the process and so the measurements must be transferred from a remote location and this can be done …

The major problem in the production of heavy oil is to determine the amount of water and to separate the water from the oil. The water cut in the oil field refers to the mass percentage of water in all the liquids. So in oil, we can see a good amount of water so crude …
The process of isolating an object such as isolating machinery from the source of vibration is called vibration isolation. When motorized equipment such as electric motors, fans, or pumps is mounted to a solid structure then the chances of transferring energy from the equipment to the structure in the form of vibration are high. These …

A flame detector is a type of sensor that can detect and respond to the flame presence. This device is capable to determine smokeless liquid and smoke that can create open fire. In boiler furnaces flame detectors are widely used, mostly a flame detector can detect heat, smoke, and fire. This device also does fire …
What are pneumatic cylinder and what is the function of pneumatic cylinder A pneumatic cylinder is also called pneumatic actuators is a device that is used in industrial automation applications to provide motion and force. A pneumatic cylinder uses compressed air to create force. This device is widely used in automated systems, machines, and processes. …
