The Magnum IT-762 filter valve is Autotrol's 2" control valve configured for backwashing filtration media such as carbon, birm or greensand, rather than softening resin, on commercial and industrial installations. With metered control fitted, the valve initiates a backwash cycle based on actual water throughput, protecting the filter bed from channelling and premature exhaustion on sites with high or variable flow. This is a complete replacement valve assembly built for the Magnum-format tank, and is stocked by WrekinWater for engineers replacing a worn or failed filter valve on a large-format system.

Symptoms that mean you need this part
- The valve fails to trigger a backwash cycle even though flow has clearly passed through the meter
- Water quality after the filter has deteriorated, suggesting the bed is channelling due to inconsistent backwashing
- The valve body shows cracking or leaks at more than one point that a seal kit alone won't fix
- The current mechanical or time-clock filter valve is being upgraded to metered control to match variable site demand
- Persistent drive or meter faults point to worn internals rather than a single failed part
Why it fails / why it matters
A commercial filter valve like the Magnum IT-762 controls backwash timing for the whole filtration bed, and on sites with heavy or fluctuating flow, metered control is what keeps the bed backwashing in line with real usage rather than a fixed schedule that either wastes water or under-cleans the media. Years of high-volume cycling wear the valve body, seals and injector system past the point a repair kit can restore, and once that happens the valve needs replacing as a complete unit to bring back reliable, accurately metered backwashing.
Why buy this from WrekinWater
WrekinWater has supplied commercial water treatment parts to installers and engineers for over 15 years from its Bettisfield, Shropshire base, serving more than 50,000 customers and stocking the full Pentair Fleck, Autotrol, Clack and Kinetico ranges. Orders are processed promptly, and WrekinWater is rated Excellent on Trustpilot, which counts for a lot when a failed filter valve means a commercial filtration system is offline.
How to fit it
- Isolate the filter at the bypass valve and shut off mains flow before disconnecting any pipework
- Record the existing drain, backwash and wiring layout with photos before removing the old valve
- Get a competent installer or commercial engineer to confirm the Magnum IT-762 filter valve matches your tank thread, riser and flow rate before fitting
- Disconnect the drain line and control wiring from the existing valve and lift it off the tank
- Fit the new Magnum IT-762 filter valve with new manifold gaskets and reconnect drain and wiring
- Set the meter and backwash parameters to match your filter media and site flow before bringing the system online
- Restore mains supply, run a manual backwash cycle, and check for leaks before returning to normal service
