Hydraulic Pilot Valve- Operate Larger Valves from a Remote Location

Author: Milian Dixon

Hydraulics or fluid mechanics is hard to understand, especially for people who are not working directly in this field. In fluid power, hydraulics assist in generating, controlling, and transmitting power by using liquid pressure. A hydraulic system uses compressed fluid for the passage of applied force at one point to another. There are different components in hydraulics such as pumps, reservoirs, motors, valves, or cylinders.

Hydraulic valves direct the flow of liquids through hydraulic system. They are available in diverse types depending on the system type you are working with. Some of these valves can be of high frequency whereas others are low frequency valves.

Hydraulic valves help in the smooth flow of water and are installed in a systematic way. If the valves show some problems, then you can repair them yourself or call a technician for the help. It is advisable to call the professionals in case the damage is more. For minor damages, you can disassemble the parts to clean them. There are different types of hydraulic valves like:

Pilot valve

Hydraulic electric control valves

Slow shut check valves

Release valve

Pump control valves

Reducing valve

Ball valves

Telecontrol float valve

Hydraulic pilot valves are used to operate larger valves from a remote location.

Design

Hydraulic pilot valves are made up of sections, each having two 3-way pressure reducing valves. The use of cast iron valve protective cover and reducer valve spools of hard, precision-ground steel provide a longer service life with minimum internal leakage. Pedals can be pressed steel plate, corrosion-resistant, aluminium or rubber-coated steel. Special low friction seals provide impelling protection against external leakage. The PCL4 is designed to provide effective long term control characteristics and minimal hysteresis. Levers are made of corrosion-resistant steel and can be fitted easily with balls, plastic handles, or window knobs.

There are numerous characteristics of hydraulic pilot valves that one should be familiar with, like:

  • A hydraulic valve has small dimensions enabling simple, and compact installation.
  • It is strong and has simple design, which offers greater reliability and easy servicing.
  • Wll adapted and low lever forces as well as short lever strokes provide better operating comfort.
  • Low hysteresis helps in constant machine function response to valve actuation.
  • Good metering properties assist in gentle, and proportional control.
  • The extensive range of control-pressure features enables application-optimization.
  • Extensive array of control devices and other gears offer better flexibility in system design.
  • The valve can be installed on the operator seat's arm rests and fitted with site-suited lever to provide enormous engineering control station.

The proper testing of the pilot calve ensures minimum internal leakage and long service life.

Hence, these are some of the features of a hydraulic pilot valve. If you want to know more about it, then internet is the best platform to gather all the information. Today, you can find anything on the internet, be it is related to modern technology, gadgets or others. Just choose the right source to get the insight details.
