Description
The water that is extracted from the wells contains a large amount of grains and small stone materials, and the entry of mud and particles in the water from the water pump and their entry into the pipes of the drip and rain irrigation system causes them to be blocked. and will face the irrigation system with disruption and pressure drop. It also causes the wear of pumps and piping systems and water pollution in drip irrigation systems, and therefore it is necessary to separate excess solid particles from liquids. The duty of the cast iron gear valve is to prevent damage to pumps and other parts by preventing the entry of waste materials and deposits with the fluid. Geared valves use an aluminum window and a mechanism to prevent pipes from venting when the pump is turned off.
The sealing washers used among the cast iron parts are rubber type.
Valves are also available in polymer.
