Product Description
Danfoss HFI 070 F high pressure float valve, code 148G3764, a liquid level regulating (float expansion) valve for industrial refrigeration. HFI is a high-pressure float valve with an internal liquid measuring device; it is designed for direct flange mounting or welding onto plate-heat-exchanger type condensers, and can also be mounted directly on vessels. The valve is direct acting, so no differential pressure is required to activate it: the internal float senses the condensed liquid level and meters high-pressure liquid refrigerant on to the low-pressure side, maintaining the correct liquid level in the high-pressure receiver/condenser. It is equipped with a purge valve for venting non-condensable gases (e.g. air) from the top of the valve housing, which also assists servicing. Inlet connection 150 mm (6 in) flange inlet (DIN 2635/2512-F EN 1092-1 EN 10220); outlet 50 mm (2 in) butt weld; nozzle (orifice) 70 mm. Rated capacity 2400 kW (682 TR) on R717 (ammonia) at Temp. -10 - 35 °C; valve constant 100. This version has two external connections on the housing for drainage and pressure equalization. Housing (shell and flange) is special steel approved for low-temperature application. Suitable for R717 (ammonia), HCFC and HFC refrigerants with a liquid density of 500-700 kg/m³. Maximum working pressure 25 bar (363 psig); media temperature range -50 °C to +80 °C (-58 °F to +176 °F). PED category III. CE marked; EAC (EAEU) certified.

Compatibility & Fitment
Danfoss HFI 070 F is selected by refrigeration capacity and condenser/receiver connection: match the nozzle (orifice) size (70 mm), inlet connection type and size (150 mm/6 in flange), and connection standard (DIN 2635/2512-F EN 1092-1 EN 10220). Type suffix F = flange inlet; suffix FD / "two external connections" version adds housing connections for drainage and pressure equalization. Capacity 2400 kW is rated on R717 (ammonia). Float valve inserts, purge valves and seal/gasket kits are available separately as HFI spare parts.
