ZGFWF Stainless Steel Rotary Valve Configuration

A previously supplied ZGFWF configuration used 304 stainless steel with a 300 mm flange inner diameter. This dimension describes the opening, not a complete model designation or flange standard. Final model, installation dimensions and drive scope must be confirmed in the quotation and drawing.

Material and duty: conveyed material, particle size, bulk density, required capacity, pressure difference and operating temperature.
Connection: flange inner diameter, outer diameter, bolt circle, hole number and diameter, flange standard and installation height.
Drive scope: state whether you need the valve without a drive or a package with motor and gearbox; specify voltage and frequency where applicable.

Request a ZGFWF rotary valve configuration and quotation. Include an installation drawing when replacing an existing valve.
