Hydraulic systems 1 part 2

Front

What is the primary purpose of a relief valve?

Back

To limit system pressure.

Front

What is a flow control valve a combination of?

Back

A needle valve and a check valve.

Front

What is a pressure reducing valve (PRV)?

Back

A device that senses downstream pressure and is normally passing, with a drain line connected to the reservoir.

Front

What valve is used for switching between flow control valves in a multiple speed circuit?

Back

Directional Control Valve.

Front

What happens to the flow through a non-compensated flow control valve if the load on an actuator is increased?

Back

The flow will decrease.

Front

Define a hydraulic system.

Back

A system that uses incompressible fluid to transmit power.

Front

What is the function of a check valve in a hydraulic system?

Back

To allow fluid to flow in one direction only.

Front

Explain the role of a directional control valve.

Back

It directs the flow of hydraulic fluid to different parts of the system.

Front

What is the significance of a needle valve in flow control?

Back

It allows for precise control of fluid flow.

Front

What does a pressure relief valve do when system pressure exceeds a set limit?

Back

It opens to release excess pressure and protect the system.
