AUTOMATIC RECIRCULATION VALVES smartline

With bypass throttles

Our  product range, smartline, is an automatic recirculation valve for the protection of standard centrifugal pumps. The valves of the smartline range automatically protect the pumps against wear, total failure and damage caused by dry running or during low-load operation. The smartline valves are available in various sizes, all of which are located in the low-pressure range. They are suitable for various media and for admissible average medium temperatures between -50°C and 200°C.

Calculation

QByR: required bypass flow rate [m³/h]
s.g.: specific gravity [kg/dm³]
?p: differential pressure [bar]
Kv: flow coefficient [m³/h]
Cv: flow coefficient [USgpm]

Example:

medium: cooling water – s.g. = 0.992 kg/dm³ (@ 40 °C)
nominal main flow (Q100) = 153 m³/h
required minimum flow (QBy) = 62 m³/h
differential pressure @ QBy = 32 bar
