Intatec BVF35 Heat Pump Ball Valve with 500 Micron Filter – 35mm Compression
35mm Compression — Lever Ball Valve with Integrated 500µm Filter Cartridge — PN25
The Intatec BVF35 is a combination ball valve and 500 micron mesh filter in a single solid brass body with 35mm compression (both ends) ends. It provides full-bore quarter-turn isolation and inline debris filtration in one compact fitting — eliminating the need for a separate strainer in the circuit and reducing the total number of joints in the heat pump pipework.
The integrated 500µm stainless mesh filter cartridge captures debris, particles, and construction residue before they reach the heat pump heat exchanger. The lever handle gives immediate visual confirmation of valve state. The filter cartridge is removable for inspection and cleaning without cutting the pipework — simply close the ball valve, unscrew the cartridge housing, rinse and refit.

Key Features
Isolation + filtration in one body
A single fitting replaces a separate ball valve and inline strainer — fewer joints, less pipework space, and a neater installation. The lever provides immediate open/closed indication; the filter housing is accessible from below when the valve is in the closed position.
500µm serviceable mesh cartridge
The stainless mesh filter cartridge captures debris, scale, and particles down to 500 microns before they reach the heat pump heat exchanger. The cartridge unscrews from the body for cleaning or replacement without disturbing the pipework — close the ball valve, relieve pressure, unscrew, rinse, refit.
PN25 solid brass — heat pump duty rated
Rated to 25 Bar and -10 to +90°C working temperature — well in excess of the pressures and temperatures found in domestic ASHP circuits. The filter cartridge itself is rated to -20°C to +120°C, giving additional design margin. Suitable for glycol-blended systems.
Lever handle — instant visual state
The lever lies in-line with the pipe when fully open and perpendicular when fully closed — immediate visual confirmation of valve state without any tools. Suitable for accessible indoor locations where the valve does not need to be operated through insulation.
Compact 35mm compression (both ends) body
At 60.9mm body length and 110mm overall, the BVF35 is compact enough for tight plant room and manifold installations. The 35mm compression (both ends) ends connect directly to standard copper or plastic pipe using standard olives and compression nuts — no soldering required.
Protects the heat pump — and the warranty
Many heat pump manufacturers require adequate filtration to be installed as a condition of their system warranty. Fitting a filter valve on the return line protects the heat exchanger from debris damage — particularly important during system commissioning when pipework particles and flux residues are still present.
Installation & Maintenance
Install the BVF35 with the filter housing accessible — ideally oriented so the cartridge can be unscrewed downward or outward without restricting access. Install in line with the direction of flow marked on the body. On heat pump systems, the preferred position is on the return pipe upstream of the heat pump, so debris is captured before reaching the heat exchanger. Thoroughly flush all system pipework before commissioning to remove construction debris.
Check and clean the filter cartridge at commissioning (where significant debris may have been released during filling and flushing) and at each annual service visit. If the filter becomes heavily fouled between services, this may indicate a system-wide corrosion or debris issue that warrants further investigation — consider adding an Intatec IntaKlean HP magnetic filter on the same return leg to capture magnetite separately from physical debris.

Frequently Asked Questions
Where in the system should the BVF35 be installed?
Inta recommend installing the BVF35 on the return pipework, upstream of the heat pump, so any debris in the circuit is caught before reaching the heat exchanger. 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.
Does the BVF35 replace a magnetic filter like the IntaKlean HP?
The BVF35'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.
How do I clean or replace the filter cartridge?
Close 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.
Can the BVF35 be installed outdoors on the heat pump?
Technically 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 HPBV35 extended key ball valve. The BVF35 is then positioned at the accessible indoor end of the circuit.
Is the BVF35 compatible with glycol/antifreeze solutions?
Yes — solid brass ball valves are compatible with the glycol-water mixtures used in heat pump systems. The Inta Zero anti-freeze valves on the same circuit are designed specifically for water circuits; if your system uses a significant glycol concentration, confirm compatibility with Intatec's technical team for the complete circuit assembly.
