What is meant by 4 3 DC valve?
4-way-3 position direction control valve used in hydraulic system is known as 4X3 DC Valve. The valve has four ports and three positions. Following figure shows the Normal and working positions of DCV. Spool of this valve is having three positions.
What is 4/3 solenoid operated DCV?
The 4/3-way solenoid valve is mounted on a function plate equipped with four quick coupling connectors. The valve consists of: Piston (1), housing (2), spring (3), solenoid coil (4), plunger (5), spring disc (6), stem (7), emergency manual override (8), nut (9), pressure tube (10).
What is a DCV actuator?
Other terms used to describe them are bang-bang or discreet valves. They determine the path of fluid flow through a circuit and are used primarily to start, stop, accelerate, decelerate, or change the direction of motion in an actuator.
What is a 4-way directional control valve?
Four-way, directional-control valves are used to control the direction of fluid flow in a hydraulic circuit, which controls the direction of movement of a work cylinder or the rotation of a fluid motor. These valves are usually the sliding-spool type.
When the directional control valve is referred to as a 4 port 3-position spool valve What does it mean?
A 4-port, 3-position spool valve serves as a convenient illustration (Fig. 2). One port receives pressurized fluid from the pump, and one routes fluid back to the reservoir. The other two ports are generally referred to as work ports and route fluid to or from the actuator.
How DCV ports are labeled?
The four ports will always include the pump (“P”) and tank (“T”). By convention, the other two lines will be labeled “A” and “B”. Ports refer to the number of lines into and out of the valve. The press circuit DCV has four ports to connect the valve to the pump, both sides of the cylinder, and to the tank.
What type of DCV would you use to control a double acting cylinder?
four-way DCV
A four-way DCV is used to control a double-acting cylinder. When the valve is in the normal position, the pump line is connected to the end of the cylinder and the blind end is connected to the tank as shown in Fig. 3.15(a).
What are types of DCV?
So in a directional control valve, there are four methods of actuation they are manual, mechanical, solenoid-operated, and pilot-operated.
Which is standard Centre position of DCV?
a.) Open center 3 / 4 DCV : In open- center circuit, all ports are open to each other in the center position. When the valve is in open center position, the pump flow is directed to the tank at atmospheric pressure.
