Various types of pneumatic pneumatic valves often appear

pneumatic pneumatic valve is a pressure, speed, and air volume control, because it moves through the pneumatic system components of the array. Pneumatic system that relies on sending power of compressed air force, can be found in numerous industrial applications, pneumatic pressure electric tools diesel engines. On the basis of other components in a given application and the use of different pneumatic system, including several types of pneumatic pneumatic valve, may be found in the heart of the equipment. Function direction control pneumatic valve, directional airflow control, or inhibit flow together, is a kind of pneumatic pneumatic valve house multiple variants.

function direction control pneumatic pneumatic valve pneumatic valve
a lot of the classification of the function orientation of pneumatic control pneumatic valve according to the number of their entry and exit, they create the flow path, opening and closing which ports and mechanism. Two directional control pneumatic valve

bi-directional pneumatic valve through the two directions of the air, through the two ports, can be opened or closed. Pneumatic valve mouth shut, if there is no air can flow through the pneumatic valve. If the port is open, the air can be through the pneumatic valve, and through the second port, or moving in the opposite direction from the first port.

three-way reversing pneumatic valve a three-way reversing pneumatic valve has three ports, each of which provide different purposes. The first port used to connect the pneumatic valve actuator or other equipment. The second port connected to an air stream. The third port is used as a vent. As mentioned in the first and the second port is open, the third is closed, air moving through the pneumatic valve of the device. When the first and the third port is open and the second port is closed, can discharge exhaust actuators. T often in the cylinder is connected to the actuator, pneumatic valve, or used to connect to double-acting cylinder.

the a four-way reversing pneumatic valve spool pneumatic valve has four different port, two of them connected to the actuator, a connection to the pressurized air flow, and, as the exhaust passage. They are one of the most common type of pneumatic valve in the pneumatic system, because of four different paths allow pneumatic valve effectively reverse movement of the motor or cylinder. Sometimes add additional port to a four-way pneumatic valve, a four-way solenoid five ports. A four-way pneumatic valve, with an additional port is usually used to provide a double pressure, which means that the two kinds of pressure of the pneumatic valve can be used, and two alternately according to the need of application. Replaceable, the pneumatic valve can use other port as secondary vent.
spring offset
this type of pneumatic valve pneumatic classification refers to the way the switch in the direction of air flow. For example, in a two-way pneumatic valve in the direction of the control, the pneumatic valve is open, The air flow can make) Or off ( Prevent the air flow) 。 For each port, so that, assuming that open or closed position, the actuator mobile pneumatic valve position. To release the pneumatic valve pneumatic valve core, pneumatic valve, pneumatic control and return to its previous position, spring release pneumatic valve core. Two directional control pneumatic valve, in this way, the function is also called spring offset pneumatic valve.
resting state: open the rest v.
in two-way directional bias pneumatic valve spring, there are two positions, they can assume that the connection of the actuator, has not yet been activated: open or closed. Rest in an open position is a standard equipment, air move freely, by a pneumatic valve. In a closed resting state, the air flow is blocked. In the 3-way pneumatic valve, a port is always open. In this case, a closed usually cause in the resting state to block the air circulation, so the pressure is motionless, unless the device has been opened.
