What are the types of directional control valves?

- Jul 27, 2018 -

A directional control valve is defined as a directional control valve that defines a gas flow direction or an on-off control valve.

If the air is supplied to one end of the cylinder and the other end is exhausted, or vice versa; the air is exhausted from the other end and exhausted at one end. To achieve this change in flow direction, a directional control valve is used in addition to controlling the cylinder action. Can control the continuity of the entire system air.

Slow response---pilot valve failure, main valve core poor lubrication solenoid valve does not move - electrical failure - pilot valve failure (overvoltage, etc.), mechanical failure - main spool is blocked solenoid valve structure is complex, more parts The method of dissolving and cleaning foreign matter by the solenoid valve can be resumed, but care must be taken not to lose parts or mix dust.

Industrial fluid control, solenoid valve related certification solenoid valve characteristics Solenoid valve characteristics Solenoid valve fault detection Common fault types and solutions Leakage - External leakage, internal leakage - Foreign objects, spool wear, loose threads, misaligned seal positions, etc. .

Directional control valves can be classified according to the following functions according to the functional classification. Classification according to the valve body structure Classification of the flow control valve according to the classification of the flow control valve The switching port includes the inlet, the outlet and the exhaust port.
