Product description

Parameters

Electric flow regulator/jacketed flow regulating valve designed for chemical fiber and chemical fiber raw materials production enterprises and polyester polymerization device research and development of the electric flow control valve. The process piping of polyester melt flow rate, pressure, temperature, liquid level, the regulation of discharge control.

With the guide valve core structure, the structure is compact, in an s-shaped streamline channel, small pressure drop loss, large flow, adjustable range, flow characteristic of high precision, IEC534 standard. Jacketed flow control valve is suitable for the need to heat preservation, in order to ensure the body temperature in the process of running equilibrium, designed a heating jacket, double deck structure, mezzanine can steam or heat conduction oil, to maintain or increase the temperature of the fluid, avoid fluid temperature is reduced, causing viscosity increase or fluid solidification.
