Autotrol Magnum IT-742 Filter Valve with LOGIX Timer 2"

This is the filter valve configuration of the Autotrol Magnum IT-742, a complete 2" top-mounted commercial control valve fitted with Pentair's LOGIX electronic timer, built to control backwash, rinse and service cycles for media filtration beds such as iron removal, carbon or multimedia filters. It shares the same high-duty-cycle valve body and LOGIX timer as the softener version of the IT-742, but is set up to drive the filtration backwash sequence rather than a softener's brine regeneration. This is a complete replacement valve head rather than a repair part, and is the unit to order when a commercial filter's existing valve has reached the end of its service life. WrekinWater stocks this as a genuine-spec 2" Magnum IT-742 filter valve for commercial and industrial installers.

Technical specifications

Symptoms that mean you need this part

• The filter is no longer backwashing correctly and water quality after the filter has deteriorated despite fresh media
• The valve body, drive housing or LOGIX timer board has failed beyond what seal or disc kits can repair
• The valve hangs mid-cycle or won't index correctly through backwash, rinse and service positions
• You're replacing an end-of-life commercial filter valve and need a genuine-spec 2" Magnum IT-742 in filter configuration

Why it fails / why it matters

The filter version of the Magnum IT-742 directs flow through backwash, rinse and service positions to clean and reset media beds rather than regenerating resin with brine, but it's built on the same commercial-duty valve body and sees the same high flow rates and cycle counts as the softener version. Piston bore wear, drive gear wear and timer electronics failure eventually make the valve unrepairable through individual parts alone, particularly once several service kits have already been fitted, at which point replacing the complete valve is the practical fix.

Why buy this from WrekinWater

WrekinWater has supplied Autotrol and Pentair Magnum valve components to commercial installers and water treatment engineers for over 15 years from its Bettisfield, Shropshire base, and stocks the full range of Pentair Fleck, Autotrol, Clack and Kinetico components including the Magnum LOGIX commercial range. The business is rated Excellent on Trustpilot and has served more than 50,000 customers, and getting a genuine-spec replacement valve quickly matters when a commercial filtration system is offline.

How to fit it

1. Isolate the filter system at the bypass and shut off the mains supply before beginning any valve changeover
2. Confirm the media tank thread, riser tube diameter and bypass configuration match the IT-742 2" filter valve before ordering
3. Arrange for a competent installer or commercial water treatment engineer to remove the failed valve and transfer or fit the distributor/riser seal
4. Have the engineer mount and wire the new LOGIX-timed filter valve, matching the drain and backwash connections to the original layout
5. Programme the LOGIX timer for the correct backwash frequency, duration and flow rate for your filter media
6. Run a full manual backwash cycle and check all connections under mains pressure before returning the system to service
