What is the definition of pneumatic valve?

A valve which requires pressurised air to operate (open or close) is known as pneumatic valve. A valve has a valve base through which the media (could be be air, liquid, steam, gas...) flows and a actuator mounted on the base which helps operate the valve. This actuator could be of pneumatic type. (or elctrically operated motorised type)


What is the air pressure valve in the boiler heating system?

I am guessing you are talking about the air charging valve on the expansion tank. That is to charge air to the top side on the bladder which acts as a cushion and compresses to allow the water to expand due to being heated, preventing the relief valve reaching it`s setpoint and lifting.


What is a valve grinder used for?

There are many things that a valve grinder is used for. Typically, a valve grinder is used for helping a fuel air mixture to come in and to exhaust the burned gasses.


Why is a throttling valve called an expansion valve?

It is not.. A globe , needle , ball valve are used for throttling For expansion either a shock absorber , diaphragm tank or air chamber are used to allow for expansion


How does air compressor unloader valve work?

An air compressor unloader valve is designed to release air from the compressor's pump when the compressor is not running, preventing pressure build-up in the system. When the compressor reaches its cut-off pressure and shuts off, the unloader valve opens, allowing the stored air in the pump and discharge line to escape. This action reduces the load on the motor during the next startup, making it easier for the compressor to restart. Once the compressor is activated again, the unloader valve closes, allowing the system to pressurize.
