What is a meter out flow control valve?

What is a meter out flow control valve?

A meter-out flow control system is one in which the FCV is placed in the outlet line of the hydraulic cylinder. Thus, a meter-out flow control system controls the oil flow rate out of the cylinder. Meter-in systems are used primarily when the external load opposes the direction of motion of the hydraulic cylinder.

Why would a person install a meter out valve instead of a meter in flow control to control the speed of an actuator?

In order to stop your air cylinder from stuttering, you need to use a “Meter Out” configuration. Why? You always want to control the exhaust air out of a double acting air cylinder. This will give a smooth flow of the air, and act as a speed limit to the air chamber that is being pressurized.

Where is flow control valve located in meter out circuit?

The flow control is on the out let side of the cylinder to control the flow coming out. This is known as a meter-out circuit. A cylinder is speed is determined by its size and the flow rate of the oil going to or out of it.

What is meter in and meter out?

The difference between the meter in circuit and the meter out circuit are as follows. 1) In the meter in circuit the flow rate goes into the cap end of the cylinder while in the meter out circuit the flow rate comes out of the rod en of the cylinder.

Which is better meter-in or meter-out?

A meter-out circuit is the best control to avoid air-cylinder lunging. In the case of an air system, pressure builds slowly and cylinder movement may be jerky.

What is meter-in and meter-out circuit in hydraulics?

Flow control circuit: Meter-out Flow control valve will be installed on discharge end or return side of actuator i.e. cylinder in order to control the discharge of fluid flow. Meter-out flow control circuit will control the flow of fluid leaving the actuator.

Which is better meter-in or meter out?

What is meter-in and meter out circuit in hydraulics?

Where are meter-out circuits used?

A meter-in circuit is ideal in applications where a load always offers a positive resistance to flow during a controlled stroke. Examples would be feeding grinder tables, welding machines, milling machines, and rotary hydraulic motor drives.

Where is meter-out circuit used?

Meter-out circuits provide accurate speed control even with reversing loads. However, as with the meter-in system, considerable heat will be generated when used with a fixed delivery pump and a wide range of piston speeds. Applications: Drilling, Boring, Reaming and tapping operations.

Where is meter out circuit used?

What is meter in circuit?

A meter is any device built to accurately detect and display an electrical quantity in a form readable by a human being. In the analysis and testing of circuits, there are meters designed to accurately measure the basic quantities of voltage, current, and resistance.

What is a meter in flow control?

A meter-in flow control valve (also known as a reverse flow control valve) restricts the flow to an actuator. A meter-out flow control valve regulates the exhaust flow from an actuator. These are the most commonly used air flow control valves.

How do flow control valves work?

A flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Control valves are normally fitted with actuators and positioners.

What is an inline flow meter?

The inline or in-line flow meter includes a flow body that is installed more permanently in a process line. One of the advantages of the in-line meter is that it does not require as much straight run as the insertion-style meter.

What is a pneumatic flow control valve?

Flow Control Valves are used to reduce the rate of flow in a section of a pneumatic circuit, resulting in a slower actuator speed. Unlike a Needle Valve, a Flow Control Valve regulates air flow in only one direction, allowing free flow in the opposite direction.
