X1f25/15 3-port valve, flanged connections, PN16, DN25/15, kvs = 4.5 m3/h, dpmax = 600/1600 kPa (mixing)

Key data to replacement product: VXF53.25-6.3, flanged connections, nodular cast iron, PN25, DN25, kvs = 6,3 m3/h, dpmax = 1200 kPa (mixing)

Info: Consider different dimensions of valve-actuator combination, verify if Additionally order adapter ALF41B25 for bypass needs to be ordered additionally
Replace actuator (20 mm stroke), adjust electrical connections and wiring. Attention: Higher kvs value, PN25. Examine, if VXF53.15-4 with kvs value 4 m3/h is sufficient.
