Control Valves

A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller.[1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. The opening or closing of automatic control valves is usually done by electrical, hydraulic or pneumatic actuators. Normally with a modulating valve, which can be set to any position between fully open and fully closed, valve positioners are used to ensure the valve attains the desired degree of opening. LIXIN boasts extensive experience in the design and production of control valves, consistently delivering high-performance and premium-quality products to numerous clients over the years, suitable for a wide range of demanding operating conditions.
