Frese announce the launch of the pressure independent control valves

Frese OPTIMA Compact

Frese are pleased to announce the launch of the DN250 and DN300 OPTIMA Compact pressure independent control valves. The pioneering Frese OPTIMA Compact PICV range is now available from sizes DN10 to DN300 covering flow rates up to 166.7 l/s (600,000 l/h) with a differential pressure operating range of up to 800 kPa, making them perfect for applications ranging from small terminal units to large plant equipment. Pressure independent control valves combine the functions of flow, pressure and temperature control in one housing and the patented Frese OPTIMA Compact PICV is one of the most compact designs available. The combined functions of the OPTIMA Compact PICV replace the need for separate static balancing valves, differential pressure control valves and 2 port control valves simplifying the design and installation phases of a project. Whilst the dynamic balancing nature of the product also removes the need for proportional balancing, thus reducing the commissioning process. The Frese OPTIMA Compact range is available from DN10 to DN50 with male/male or female/female threaded connections and from DN50 to DN300 with flanged connections. The range is supplied with a variety of actuators including thermic on/off and modulating, motoric modulating and failsafe versions.

Extended Balancing Valve Range

Frese have extended their range of static balancing valves to include both a double regulating valve and variable orifice double regulating valve. The addition of these product ranges adds to the already existing range of fixed orifice double regulating valves used in heating and cooling systems around the world. The new Frese STBV range can be used in both variable flow and constant flow systems and offers simple and reliable flow measurement and verification. The new products also compliment other products from Frese such as the Frese FODRV and the Frese PV Compact differential pressure control valve. The range of manual balancing valves is available from DN15 to DN50 in DZR with threaded connections and from DN65 to DN500 in ductile iron with flanged connections. The threaded range has a PN25 pressure rating and the flanged range has a PN16 pressure rating. Read More
