CV-230 Automatic Chlorine Control Valves

Throughout the day, treatment facilities often experience significant fluctuations in flow demand due to changes in water usage, industrial activity, weather events, and other operational factors. Without proper feed control, these changing conditions can result in underfeeding or overfeeding chemicals, leading to treatment inefficiencies, increased operating costs, and potential compliance concerns.

Automatic feed control technology helps facilities respond to these varying conditions by continuously adjusting chemical feed rates to match system demand. By automating dosing adjustments, operators can improve process efficiency, reduce chemical waste, maintain consistent treatment performance, and support regulatory compliance.

The CV-230 Automatic Chlorine Control Valve from Hydro Instruments, in particular, provides a dependable solution for facilities seeking automatic proportional feed control. The valve is compatible with chlorine gas, sulfur dioxide gas, ammonia gas, sodium hypochlorite, and other liquid chemicals, making it a versatile choice for a wide range of treatment applications. 

Whether installed in a municipal water treatment facility, wastewater treatment plant, or industrial process system, our CV-230 automatic control valves help maintain accurate dosing while simplifying day-to-day operations.

How CV-230 Automatic Chlorine Control Valves Work

Rather than relying solely on manual adjustments, the CV-230 is engineered to provide automatic proportional feed control, allowing chemical feed rates to automatically increase or decrease in response to changing process demands.

One of the key advantages of the CV-230 is its versatility. The valve is suitable for both gas and liquid feed applications, allowing facilities to utilize a single automatic control solution across multiple treatment processes. No matter if they are controlling chlorine gas for disinfection, sulfur dioxide for dechlorination, ammonia for chloramination, or sodium hypochlorite for liquid chemical feed applications, our CV-230 control valves deliver dependable performance and accurate dosing control.

The result is a highly responsive feed control system capable of adapting to changing process conditions while helping operators maintain optimal treatment performance.

Applications for Our CV-230 Automatic Control Valves

The CV-230 is designed for a broad range of treatment applications where chemical feed rates must adjust automatically to changing flow conditions.

Some of the most popular applications for these CV-230 chlorine control valves include:

  • Municipal Water Treatment Plants: The CV-230 helps operators achieve accurate disinfection and treatment by automatically matching chemical feed rates to system demand.
  • Wastewater Treatment Facilities: Wastewater treatment plants often experience significant flow variations throughout the day. The CV-230 supports efficient treatment processes by automatically adjusting chemical feed rates for disinfection, dechlorination, odor control, and other treatment requirements.
  • Industrial Process Water Systems: Many industrial operations require carefully controlled chemical feed systems to maintain product quality and process efficiency. The CV-230 control valves provide reliable automatic control for process water treatment applications where consistent dosing is critical.
  • Cooling Water Applications: Cooling towers and cooling water systems frequently require chemical treatment to control biological growth and maintain system performance. An automatic proportional feed control then helps ensure treatment chemicals are delivered accurately as flow conditions change.
  • Odor Control Systems: Facilities utilizing chlorine, sulfur dioxide, ammonia, or other treatment chemicals for odor control can benefit from the valve’s ability to automatically respond to varying process demands. This helps maintain effective odor management while minimizing unnecessary chemical usage.
