Waterworks Water system

Water is the source of life. The origin of humanity is due to water. More than 90% of the human body is composed of water. The constant renewal of cells and the metabolism of life are inseparable from the nourishment of water. Water is the most important substance that constitutes the human body.

Due to human and natural factors (industrial sewage and domestic water), raw water contains a variety of impurities. From the perspective of water supply, these impurities can be divided into three categories: suspended matter, colloid, and dissolved matter. The city's water plant is to remove these raw water components that may cause harm to humans and industry, so that the purified water can meet the needs of people's life and industry.

The conventional water production process of waterworks can not be separated from the use of valves from raw water intake, flocculation and sedimentation in sedimentation tank, filter filtration, to the final output water supply of the outlet pump house. However, the requirements for valve selection are very different at different locations. The main differences are in the caliber of the valve, the type of valve and the control method of the valve.Bundor Valve will provide you with a complete set of valve application solutions in the water pipe of the waterworks.

Valve selection of water system in Waterworks

Raw water intake valve: the valve of the head raw water is characterized by large caliber, no need to operate frequently, and the valve is in the normally open and closed state for a long time. Select the valve as the manually operated gate valve or butterfly valve.

Pump room valves: The valves in the pump room are mainly the inlet valve, outlet valve, maintenance valve and check valve on the pump unit. The first three valves are basically butterfly valves. The check valve is usually a silent check valve with a slow-closing check valve with a slight resistance.

Dosing system valve: the characteristics of the dosing system in the waterworks determine that the valve used on it should have a small caliber and a small flow rate, but it requires high flow regulation, high accuracy requirements and fast regulation speed, therefore, the flow regulation valve is usually selected.
