Siemens VXF53.150-400 Flanged 3-Way Control Valve DN150 PN25
Siemens VXF53.150-400 Flanged 3-Way Control Valve DN150 PN25
The Siemens VXF53.150-400 is a flanged 3-way seat control valve. In size DN150 with a kvs value of 400 m³/h, it provides mixing or diverting control in air handling unit, boiler room, heat exchanger and district heating circuits. Body material: ductile iron EN-GJS-400-18-LT. Suitable medium: hot water. Medium temperature range is -20…220 °C.
The valve is operated by a linear electromotive or electrohydraulic actuator; the actuator is selected according to stroke and close-off pressure. Siemens actuators verified with this series are listed below.

Selection and installation notes
- The kvs value is selected according to the required pressure drop across the valve at the design flow rate; an oversized kvs reduces control quality.
- When selecting the actuator, choose an actuating force suited to the valve's stroke and close-off differential pressure.
- For glycol-water mixtures or special media, verify the valve's media compatibility in the datasheet.
