Control valve (or control nozzles) are crucial in most sectors. They are employed to control distinct conditions like temperature, pressure and liquid level by partially or fully opening the valves in response to the signals received in the controllers. The controls use the value provided by the sensors to compare the “setpoint” to the “process variable”.

The opening and closure of control valve are done through pneumatic, electric or hydraulic systems. The hydraulic control valve are those which are controlled by hydraulic pressure. These control valves consist of a main valve and attachments such as pilot valve, pipeline, ball valve, needle valve and manometer.

The hydraulic valve are simpler to install and keep. There are lots of things you should bear in mind while installing a hydraulic control valve. You will need not add these hydraulic control valves and motor oil as they make great use of run water that is smooth.

Control Valve

Any maintenance to the hydraulic control valve should be done carefully. Then the following instructions should be kept in mind before setting out to get the main valve ready, if the spare parts of it are damaged.

1. If the mebrane or 0 – ring is damaged, then solve them. When it is done you can install the new mebrane and the oring.

2.Remove in order to find out whether o ring and the marine are damaged. Then do not subdivide the spare parts by yourself, if they are not damaged.

These measures ensure that the hydraulic control valve is safely fixed with no damage.
