Tips For Maintenance of Hydraulic Control Valves

Hydraulic Control System

Hydraulic Control System are essential in most industries. They are used to control different conditions such as temperature, pressure and liquid level by partially or fully opening the valves in response to the signals received from the controllers. The controllers use the value provided by the sensors to compare the “setpoint” to the “process variable”.

The opening and closing of control nozzles are done by means of hydraulic, electrical or pneumatic systems. The hydraulic control nozzles 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. On the basis of its function, use and different occasions it evolve into reducing valve, telecontrol float nozzle, release nozzle, flow control nozzle, etc.

The hydraulic nozzles are easier to install and maintain. There are some things that you should keep in mind while installing a hydraulic control nozzle. You need not add motor oil to these hydraulic control valves as they make good use of smooth run water.
Any maintenance to the hydraulic control nozzles should be done carefully. At times damages can be caused to the valves as a result of your carelessness. If the spare parts of the main valve are damaged, then the following instructions should be kept in mind before setting out to get it ready.

1. Remove the different parts and find out whether the marine and o-ring are damaged. If they are not damaged, then do not further subdivide the spare parts by yourself.
2. If the mebrane or 0-ring is damaged, then resolve them slowly. When it is done you can install the new mebrane and the o-ring.

These steps ensure that your Hydraulic Control System is safely repaired without any damage.
