Sizing Example: ∆pmax = Maximum permissible differential pressure across the valve’s control path, valid for the entire actuating range of the motorized valve ∆pv100 = Differential pressure across the fully open valve and the valve’s control path by a volume flow V100 V&100 = 100 kPa = 1 bar ≈ 10 mWS 1 m3/h = 0.278 l/s water at 20 °C 1 V&100 2 ∆pv100 3 → kvs-value = 0.083 l/s = 9 kPa = 1.

We recommend installation in the return pipe, as the temperatures in this pipe are lower for applications in heating systems, which in turn, extends the stem sealing gland’s life. Recommendation: Always use a strainer upstream of the valve to increase the valve’s functional safety. Mounting notes Both valve and actuator can easily be assembled at the mounting location. Neither special tools nor adjustments are required. The valve is supplied with Mounting Instructions 4 319 9526 0.
