1 V2075, V2077 Flowshare Valve THERMOSTATIC TWO-WAY FLOWSHARE VALVE Application Thermostatic flowshare valves control the output of radiators in vertical one-pipe heating systems. Heating water not required is diverted through the bypass into the return. The valve is controlled by a Honeywell radiator thermostat. In the starting position the valve is to the pre-set value. The radiator proportion can be pre-set from 35 to 60% and is supplied with a setting of 35%. The valve is suitable for use with all Honeywell radiator thermostats. An additional extension tail, injector and lockshield valve can be installed to avoid heating up of the radiator through the return see Accessories on page 3. Features Stepless, concealed pre-setting of the flow, factory set at 35% radiator proportion Low noise Exchange of valve insert or O-ring insert without draining With beige protection cap Specifications PRODUCT DATA Design The Flowshare Valve consists of: Valve housing PN10 with externally threaded connections for pipe, bypass and radiator Pre-settable valve insert Protection cap Materials Valve housing made of red bronze RG5 according to DIN 1705 Valve housing made of brass with EPDM O-rings Spindle made of stainless steel Protection cap made of beige plastic Medium Heating water ph-value 8...9,5 Operating temperature max. 130 C (266 F) Operating pressure max. 10 bar (232 p.s.i.) Differential pressure max. 0,2 bar (2,9 p.s.i.) kvs-values 2,1...2,7 depending on valve housing, see table on 2 Thermostat thread M30 x 1,5 Closing dimensions 11,5 mm Function The Flowshare Valve was designed for use with a radiator thermostat. Depending on the room temperature heating water is partly diverted through the outlet into the radiator and partly through the bypass into the return pipeline. When the room temperature falls the valve is ed by the radiator thermostat and more heating water can flow into the radiator. When the room temperature rises the valve is and the heating water is diverted past the radiator into the bypass. Copyright 2001 Honeywell AG All rights reserved EN0H-193GE25 R0101
