VALVES THAT DO NOT NEED TO BE OPENED PRIOR TO WELDING AND A THREE-WAY BY-PASS VALVE FOR HEAT PUMPS AND LIQUID DRAINS
Robinet (RFF) has now designed a range of refrigeration valves suitable for all refrigerants CO2 / NH3 / R types to 65 bar. The following sizes apply: 4/8/10/15/20/25mm. These valves incorporate a newly designed spindle seal constructed from two PTFE cones and labour saving metal body gasket.
Two further developments by RFF have led to the production of valves with enclosed spindle extensions for use with thicker insulation and a new valve body with side port for valve draining and venting.
The Robinet (RFF) three-way by-pass valve is manufactured suitable for four size connection DN20/25 full bore and DN32/40 reduced bore. Connections for brazing class B.
The body is cast in one piece and can be supplied with electrical actuator. The valve is designed for heat pump by-pass, or liquid drain applications, temperature range -50oC / + 150oC.
