Description
The CSA Model Italica 353 is a needle pattern hydraulically operated automatic control valve that modulates in response to signals applied to the solenoids valves. Thanks to CSA needle valves located on the circuit the reaction time of the opening and closing can be adjusted, independently one from the other, to ensure a smooth and accurate regulation. A manual emergency circuit is usually supplied with valve in case of power failure. Normally equipped with 4-20 mA position transmitter and made in ductile cast iron with FBT (fluid bed technology) epoxy coating and stainless steel, the valve reduces head loss, throttling noise and cavitation damage.
