Application

Manual pneumatic integrated, membrane pneumatic proportional control valve, which can be applied to various flow control and adjustment systems, and can be applied in various industrial fields such as chemical, sewage treatment, dairy, food, beverage production, pharmaceutical and fine. Industrial fields such as chemical industry. The most important applications are pressure control, flow control, liquid level, temperature control, etc. The pneumatic regulating valve is a conical valve core. The valve for controlling the flow rate is controlled by the positioner. The valve positioner can also be connected with an external transmitter to realize self-adjustment and control flow, temperature, liquid level and pressure through PID calculation.
