Product Information

The Autotrol® 255 Valve features a rugged, robust, re-engineered design that uses less water, runs quieter and lasts longer. Combined with the 440 Clock Timer, it provides even more economical, convenient conditioning of your water supply.

Designed for simple, straightforward, fully automatic water conditioning, the 255 Valve/440 Control unit is built for years of heavy-duty use. Its efficient, direct-acting system functions independently of water pressure.

During normal conditioning, raw water enters the system through an inlet at thetop of the conditioning tank. As it seeps down through the conditioning bed, foreign particles and minerals are collected on the ion exchange sites of the resin, so that you can enjoy the quality, and convenience of conditioned water. During the regeneration cycle, the 255 valve automatically regenerates the ion exchange resin.

Fast, easy settings for even greater water savings.
With just two simple settings, your 255 Valve with the 440 Clock Timer Control can be programmed to automatically initiate the regeneration of your water conditioning system...and save water with each regeneration.

• The redesigned valve uses substantially less water to regenerate the system.
• Larger, stronger injector and screen caps seat positively for better operation.
• Redesigned valve disks ensure positive sealing and last longer.
• New streamlined interior valve sections allow for better flow rates.
• Regeneration frequency is easily set by positioning pins on a skipper wheel.
• Time of day is easily set with a 24-hour timer knob.
• Daily regenerations can be scheduled for up to 6 or 7 consecutive days, depending on the timer option selected.
• An extra regeneration can be initiated manually.
• Simple design and rugged construction ensure years of trouble-free performance.
• No moving parts in the water stream helps to prevent fouling, especially in iron-bearing or other types of problem water.
• Flapper-type valves are held closed by water pressure to ensure a leaktight seal.
• A unique, convenient separation feature allows the control module to be entirely removed from the valve by simply pulling out the locking bar.
• An automatic backwash controller is incorporated right into the system.
• An internal bypass automatically provides water while the system is being regenerated.
• The optional 156 Bypass Valve allows the entire water conditioning system to be bypassed when necessary.
