The preferred position is at the first accessible indoor point — after the flexible hose enters the building — where the lever and filter cartridge remain accessible for servicing without disturbing the outdoor insulation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 14px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eDoes the BVF28 replace a magnetic filter like the IntaKlean HP?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eThe BVF28's 500µm mesh captures physical particles and debris. A magnetic filter captures magnetite (black iron oxide sludge) which a mesh cannot. For a complete filtration strategy — particularly on systems with steel radiators, which generate magnetite over time — both should be fitted. The BVF filter valve and an IntaKlean HP magnetic filter complement rather than replace each other.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 14px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eHow do I clean or replace the filter cartridge?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eClose the ball valve fully, then relieve system pressure at a suitable drain point. Unscrew the filter cartridge housing from the underside of the valve body. Remove the mesh cartridge, rinse under clean water to clear debris, inspect the mesh for damage, and refit. If the mesh is torn or deformed, replace the cartridge with a genuine Intatec replacement part. Inspect at commissioning and at every annual service.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 14px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eCan the BVF28 be installed outdoors on the heat pump?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eTechnically the PN25 solid brass body is suitable for outdoor temperatures. However, the lever handle design means the valve cannot be insulated and sealed in the same way as a K-type extended key valve — the lever prevents a sealed insulation envelope. For the outdoor position directly on the heat pump where Part L insulation is required, use the HPBV28 extended key ball valve. The BVF28 is then positioned at the accessible indoor end of the circuit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 14px; border-left: 3px solid #008377CF; padding-left: 14px;\"\u003e\n\u003cp style=\"font-weight: bold; color: #008377cf; margin-bottom: 4px;\"\u003eIs the BVF28 compatible with glycol\/antifreeze solutions?\u003c\/p\u003e\n\u003cp style=\"margin: 0; font-size: 14px;\"\u003eYes — solid brass ball valves are compatible with the glycol-water mixtures used in heat pump systems.
