Frese, the company behind the OPTIMA Compact pressure independent control valve range, have introduced a new ductile iron version available in DN40 and DN50 sizes.
The new variants of the Frese OPTIMA Compact PICV use the same patented, compact design technology that allows higher flow rates to be achieved through smaller-dimensioned valves. The latest additions can accurately control flow up to 11,500 litres per hour with a maximum differential pressure of 400kPa. In addition to flow and pressure control, the Frese OPTIMA PICV provides full stroke, modulating control irrespective of the flow set point and is supplied as a package with a 0V–10V or 3 position actuator for efficient temperature control.
The Frese OPTIMA Compact PICV offers many benefits over traditional balancing valves including eliminating overflows, replacing the need for a traditional balancing valve and 2 port control valve at terminal connections and removing the need for additional system differential pressure control valves.
The DN40 and DN50 versions have a PN25 pressure rating and are supplied with female connections and 1” PT plugs. The Frese OPTIMA Compact range is available in sizes DN10 to DN100, covering flow rates up to 90,000 l/h.
