LTD Automation is an authorized distributor of PROVAL (Korea) high-performance industrial control valve solutions. High-precision engineering designed for high differential pressure, extreme temperatures, and severe operating conditions.
PROVAL's High Pressure and Temperature Service Globe Valve series is specifically engineered for industrial systems operating under severe differential pressure and temperature environments. Utilizing a linear moving Plug mechanism relative to the Seat, the valve precisely controls flow area and media capacity. Integrated with pneumatic diaphragm/cylinder actuators and smart positioners, it seamlessly receives PLC/DCS signals for full process automation.
PROVAL is a premier manufacturer specializing in the design, engineering, and supply of industrial control valve solutions headquartered in South Korea. PROVAL products are built to handle rigorous flow, pressure, and temperature regulation in harsh industrial operating environments.
With a strong focus on high-precision machining, robust body design, and stable flow control performance, PROVAL control valves are widely deployed in thermal power plants, oil & gas facilities, petrochemical industries, metallurgy plants, and high-pressure steam systems.
