What is a pilot valve and how does pilot valve work Pilot valves are valves that can control high flows in a system. Mostly the pilot actuated valves are shifted by the pressurized fluids. When the set pressure is reached then the…
What is a poppet valve and what does it do The poppet valve is used to control the flow, it could use a disc, ball, or cone to control the flow. Poppet valves are directional control valves and these valves would act…
What are the types of pressure control valves The major function of a pressure control valve is to protect the system from overpressure. This pressure could occur due to the decrease in fluid demand or it can also happen because of the…
What is a directional control valve The directional control valves can be used to start, stop, and to change the fluid flow in a hydraulic system. The major function of a directional control valve is to control the direction of flow in…
What is unloading valve and what does it do Unloading valves are used in hydraulic circuits, these valves would stop or remove the flow of the pump back to the tank when the machine is not operating. So by this reduction of…
A bleed valve is a valve that is used to isolate the flow of the fluid or air. Bleed valves are mostly used in many industrial applications such as piping systems and in heavy-duty gas turbines. The inlet of the bleed valve…
What is a breather valve and what is the use of breather valve Breather Valve is a pressure relief valve and it is used as a protective device in storage tanks. Breather valves are mostly used for atmospheric and low-pressure storage tanks….
How to do the control valve inspection and maintenance The service life of a control valve could be increased by doing proper maintenance. The internal parts of the control valves must be checked, before doing any inspection the valves must be dismantled….
What is a capillary tube and for what purpose it is used Capillary tube can be considered as an expansion device, this device is also known as a metering device it is a throttling device and it is used in air conditioning…
What is air valve and why air valves are used Air valves are used in pipelines, these valves are capable to introduce or remove the air from the pipeline. In a pipeline, air must be removed or reduced otherwise it would create…
