Frese Optima valves are now more compact

Frese, Optima valve, commissioning, PICBV

Frese’s Optima Compact range of valve combines pressure-independent balancing and control of hydronic systems. They can be used with fan-coil units and chilled beams and remove the need for separate double-regulating valves, 2-port control valves and differential-pressure control valves.

These valves combine all the benefits of the original Optima PIBCV, including accurate flow limitation, differential-pressure control and temperature control in a valve that is much more compact.

Optima Compact is available in sizes DN10 to DN20 with motorised and thermic actuators to provide linear or equal-percentage control characteristics. These valves are available without or without PT plugs and with a choice of male, female or union connections.
