Sudbury International’s recirculation control valves provide reliable protection for pumps

Recirculation control valves are available.

Renowned for its expansion joints, especially non-metallic ones for ducting systems, Sudbury International Engineered Products Limited has a diverse product lineup that also includes specialty soot blowers, slide pads, and recirculation control valves. These are control valves that provide reliable protection to make sure pumps are never damaged from running dry. Recirculation control valves are automatic control valves for pumps, which are always high in demand for applications in industrial fluid power.

Custom-built for any requirement

These valve units control liquid flow by changing the size of a flow passage, as per direction from a controller signal. This enables direct control of flow rates and consequential control of temperature, pressure, fluid level, and other process quantities. Sudbury International recommends these products for providing automatic protection of centrifugal pumps when they operate under light loads. If the flow rate drops below a predetermined level, the valve opens a bypass flow path, which ensures that the flow rate is returned above the minimum level and kept there.

Designed for optimum performance, these recirculation control valves can be custom-built to comply with any specific customer requirement. One of the most common reasons for investing in them is for scenarios that involve pumping hot water, such as cooler applications or boiler feeding. In these tasks, evaporation can cause a pump to run dry without any recirculation control valve to offer protection. Another popular reason to buy these valves is to protect high-performance pumps during startup applications.

The supplier offers other kinds of valves in stock besides recirculation control units. Also available for customers are high-pressure valves and specially designed models, which are a good choice for applications in a variety of industries, such as electrical utilities, processing, smelting, pulp and paper, and petro-chemicals. Sudbury International can meet the specific needs of a wide, diverse customer base with its flexible capabilities.

Since it was established in 1975, Sudbury International has continued to offer great industrial solutions such as these. The company’s background and experience of nearly 50 years allows it to provide the appropriate recirculation valves for any application.
