Manual balancing valves
ICV¡¯s manual balancing valves effectively solve the static pressure imbalances in the hydraulic system. The intelligent design ensures they do this precisely over the entire set-range of the valve. Static balancing valves solve the static pressure imbalances caused by the fixed equipment itself.The high grade ductile iron and the crosslinked epoxy coating thoroughly safeguards the valve
In hydraulic systems, static balancing is essential to ensuring that all coils and users in a hydraulic system receive the minimum required flow to maintain the desired room temperature. Static (fixed) pressure imbalances are caused by uneven pressure drop (resistance) in different sizes and placement of pipes, coils and all other equipment in the hydraulic system. This typically means that larger equipment in an uncontrolled system close to the pump receives an oversupply while (smaller) equipment further away receives an underflow of energy. Designers typically prefer to slightly oversize piping (to ensure supply safety in case of miscalculation and if the system later is expanded) and then control the fixed pressure imbalances using manual balancing valves on risers, mains and branches. ICV¡¯s manual balancing valves effectively solve the static pressure imbalances in the hydraulic system. Static balancing valves solve the static pressure imbalances caused by the fixed equipment itself. Static balancing is required to solve static imbalances. for dynamic imbalances please see ICV's range of dynamic balancing (series 951 PICV, 955 for fancoils, series 908/03 differential pressure balancing valves, series 952/3 dynamic/automatic balancing valves).

The fixed KV ring (visible beneath the red measuring port) ensures constant KV (the fixed orifice ring does not have a changable Kvs value, and the accuracy therefore remains at ¡À5% irrespective of the handwheel setting. This is especially important for small pipes where higher accuracy is required. Variable orifice valves (without orifice rings as flanged manual balancing valves typically are) may experience lower accuracy at extreme settings (very small or very large)
