Needle Valve: How does a needle valve work And functions?

The needle valve is named for the conical rod that acts as a plug over a small diameter hole in relation to the nominal diameter of the valve. The displacement of the rod, if it is of fine thread, is slow and the fact that until a good number of turns is turned the section of passage of the fluid i… Continue to read

Butterfly valve: Advantages and disadvantages of butterfly valves

A butterfly valve is a device for interrupting or regulating the flow of a fluid in a conduit, increasing or reducing the passage section by means of a plate, called a "butterfly", which rotates on an axis. By decreasing the passage area, the local pressure loss in the valve increases, re… Continue to read

Gate valve function: What is a gate valve and what is it for? What are its characteristics? What benefits can I get using a gate valve?

Gate valve function The gate valves are mainly used to allow or not to pass a fluid (ON-OFF) and are not designed to regulate it, which indicates that they must be completely open or completely closed so that their interiors (seat and wedge) are not worn out prematurely by the fluid and its pressu… Continue to read

Hydraulic Pumps: Basic Engineering Principles of Hydraulic Pumps

The hydraulic pump is a device that transforms mechanical energy (torque and motor speed) into hydraulic (flow). When a pump operates, it fulfills two functions: first, its mechanical action creates a vacuum in the suction which allows the atmospheric pressure to force liquid from the tank or reser… Continue to read

Hydraulic pump type - What are they?

Hydraulic pump type - What are they? Contrary to what many people think, hydraulic pumps are not capable of generating a pressure, they only provide a flow, as constant as possible, to the circuit. The pressure appears when the flow supplied by the pump has to overcome some resistance. What is true… Continue to read
