Water Supply and Distribution System

Distribution Lines
Distribution pipelines are an important part of the water supply system, responsible for delivering treated clean water to various users. These pipelines require efficient and reliable valve actuators to control the direction and pressure of water flow to ensure the stability and safety of water supply.
Pumping stations
Pumping stations play a key role in water supply systems, pumping water from the source or treatment plant to the distribution network by pressurizing it. Valve actuators are used in pumping stations to control the flow and pressure of the pumps, prevent water hammer, and optimize energy consumption.
HVAC systems
In large buildings or industrial facilities, HVAC systems require large amounts of cooling water or hot water. Valve actuators are used to control the flow and temperature of these water systems to ensure efficient operation of the system.

Advanced Water and Wastewater Applications

Decentralized Treatment
Decentralized treatment systems place water and wastewater treatment facilities close to the point of demand or water source, reducing water transportation costs and environmental impact. Valve actuators are used in these systems to control water flow and pressure, ensuring efficiency and flexibility of the treatment process.
Waste-to-Energy
Anaerobic digestion or other technologies are used to convert organic matter in wastewater into energy (such as biogas). Valve actuators are used to control the flow of materials and gas emissions during anaerobic digestion to ensure safe operation of the system.

Wastewater Treatment and Management

Sewage Plant Blower Discharge
Blowers in sewage treatment plants are used in aeration tanks to provide oxygen to promote microbial decomposition of organic matter. Valve actuators are used to control the exhaust pressure and flow of the blowers to ensure the stability and efficiency of the aeration process.
Chemical treatment
Chemical treatment is an important part of wastewater treatment, including adding chemicals to remove pollutants, adjust pH or disinfect. Valve actuators are used to accurately control the amount of chemical addition to ensure the treatment effect.
Fire Protection Systems
Fire protection systems require reliable water supply and pressure control to ensure a quick response in emergency situations. Valve actuators are used to control the pressure and flow of fire protection water supply systems to prevent system leaks or overpressure.

Pneumatic Diaphragm Valve with Double Acting Actuator

Pneumatic UPVC Double Union Diaphragm Valve

Hearken Pneumatic UPVC Diaphragm Valve offers an optimal combination of corrosion resistance and serviceability. The valve’s body, constructed from durable UPVC , provides broad chemical compatibility, while its innovative double union design allows the main valve body to be removed from the pipeline for maintenance without disturbing the pipe connections. At its core, a flexible diaphragm isolates the process fluid from all mechanical parts, ensuring zero external leakage and protecting the actuator from corrosive media.
