What Industrial Control Valves Do
Industrial control valves regulate the movement of liquids, gases and steam within pipelines and industrial process systems.
An industrial control valve is a mechanical device used to regulate the flow, pressure or temperature of fluids within a system to maintain stable operating conditions.
Control valves help manage key process variables including:
 • Flow rate control
 • Pressure control
 • Temperature control
 • Level control
Many industrial control valves operate within automated systems where sensors and process instruments send signals that adjust valve positions. This allows operators to maintain precise control over industrial processes while improving efficiency and safety.
Without properly specified industrial valves and actuators, systems may experience pressure instability, cavitation and excessive SPL’s, reduced efficiency or equipment damage.
At Unyazi we help ensure that control valves are suited to the specific requirements of process conditions.
Industries We Support
Industrial control valves and actuators are used across a wide range of sectors where precise process control is essential.
In the oil and gas industry, industrial control valves regulate hydrocarbons and gases across pipelines, refining systems and processing facilities.
Power generation facilities rely on industrial valves to manage steam systems, boiler feedwater control and cooling processes that support efficient electricity production.
Mining and mineral processing operations require durable valves capable of handling abrasive slurry systems and demanding operating environments.
Water and wastewater treatment facilities depend on control valves to regulate water flow, maintain pressure and support treatment processes.
Chemical manufacturing requires precise control of fluid systems to maintain safe production conditions and consistent product quality.
The pulp and paper industry uses industrial valves to regulate chemical treatment processes, steam control systems and water management across production facilities.
Across each of these industries, reliable industrial control valves help maintain stable and efficient operations.
