Autotrol 273/278

Good Water Warehouse Autotrol 273/278 Autotrol 273/278 Both still available at Good Water Warehouse is a rugged, high-flow valve series specifically designed for water conditioning of residential and commercial applications. Featuring high quality construction, simplified programming options and advanced cycle controls, the 2850 Series provides long lasting and reliable water treatment performance even in the harshest environments. It is intended to provide a 25 GPM flow rate as well as backwashing of up to 20 GPM, and hence is suitable for not only single but also multiple tanks.

With this solid state, memory retained valve is recommended as a top value alternative for the small to mid size residential mechanical valve.

Core Features and Functional Benefits

Rugged Design for Longevity

• Fiber reinforced polymer valve body withstands extreme environmental and operating conditions; Includes 1" fitted male NPT inlet and outlet.
• Flapper is Duraflow for frictionless sealing and the flapper is exposed to the water dissipating unnecessary wear
• External protective housing protects parts from water inlets and light conditions

Smart Control and Flexibility

With adjustable 3-or 5-cycle programming for clean, fresh water regeneration and adjustable salt settings to ensure the only time salt is used is when you decide.

• Optical sensor for precise valve cycle placement to ensure reliable treatment operation
• Programs are saved in non-volatile memory, guaranteeing no lost data in the event of a power outage
• History tracking for the system is provided for performance diagnosis and usage reporting

High-Performance Flow Capacity

25 GPM continuous service flow with less than 5 psi pressure drop

• Handles a backwash flow rate of up to 20 gallons per minute for tanks up to 21" (softener) or 18" (filter) diameter
• Perfect for residential apps or multi-tank / light commercial systems

Electrical and Power Features

• Works on 12v AC input using energy efficient controller
• Super capacitor holds time-of-day clock setting during power outages
• Energy efficient (average power usage of 3 watts) for low power systems

Various adapters for world-wide travel available, including North America, UK, Europe, Japan, Korea, Taiwan, and Australia
