FRESE Alpha Automatic Balancing Valve is particularly designed and manufactured for automatic flow balancing of the heating and cooling circuits without any adjustment to the valve during commissioning. The balancing occurs by means of a flow rate cartridge, in which the differential pressure is held constant across an orifice plate. The result is a constant flow through the valve irregardless of inlent pressure fluctuation.

HATTERSLEY Flex Check Valve is designed with 100% full flow area and provides 25 years warranty on hinge. The seating surface is constructed at a 45 degree angle, moderate disc travel and permit optimum flow rates. The disc resulting 35 degree stroke combined with its flexible action significantly reduce the valve closing time and restricting both flow reversal and 'water hammer' effect.
