Mount Belimo 2-way control valves as throt- tling devices in the return. This ensures lower thermal loads on the sealing elements in the valve. The specified direction of flow can be found in the further notes for project planning for characterised control valves and globe valves.Throttling circuit∆pv100 > ∆pVR/2 Typical values: 10 kPa < ∆pv100 < 200 kPaInjection circuit with 2-way valve∆pv100 > ∆pVR/2 Typical values: 10 kPa < ∆pv100 < 200 kPat21t1∆pVR∆pVR6-way characterised control valvesBelimo 6-way characterised control valves have been specially developed for use with combined heating and cooling elements. A 6-way characterised control valve performs the function of four 2-way valves or two 2-way valves and one changeover valve. The following design is performed with the 6-way characterised control valve for every sequence (heating and cooling).Typical values: ∆pv100 ≤ 100 kPa For low-noise operation: ∆pv100 ≤ 50 kPaLegend:MControl valve, 2-way, with actuator
