Pettinaroli Dynasty 92 Series is a diaphragm type pressure independent balancing control valve that combines the usual high accuracy and durability of existing PICV valve range with the added benefit of operating in heavily contaminated water. The valve has a Linear characteristic and it has also been designed to allow the internals to be removed, clean and replaced without effecting the performance of the valve. It comes in extensive sizes from DN15 to DN50. It also has a wide range of actuators such as thermal electric actuator and electromotive actuator to cope with the requirement of the user.

Pressure Independent valves are control valves with an automatic balancing function. An in-built pressure controller keeps a constant differential pressure over the control valve, ensuring full authority and automatic flow limitation.

The new Dynasty 92 range of PICV has been designed to provide flow limitation and temperature control of heating and chilled water systems to terminal units. The Dynasty valve provides good control of water to water heat exchangers and is ideal for use in Heat Interface Units were water quality is difficult to maintain, due to the difficulty in accessing every unit. The Dynasty valve can also be fitted in valve assemblies to be connected to Fan Coil Units.
