The Valve 1" Motorized Drain (120V) is a heavy-duty blowdown valve engineered to allow automatic pressurized draining of the Mr.Steam Commercial CU generator's pressure vessel. Part of the optional CU81600-1 Automatic Blowdown System, this valve works in tandem with the system's Digital Blowdown Timer and Time Delay Relay Board to discharge minerals and salts from the boiler at scheduled intervals, helping maintain heating element performance over time. Its heavy-duty construction makes it especially valuable in areas with hard water, where mineral buildup can accumulate faster and place greater strain on system components without regular blowdown maintenance. Featuring a 1" NPT, normally-open, 120V drain valve assembly with 1" generator connection fittings, this valve installs directly into the existing blowdown plumbing for straightforward replacement. As a genuine Mr.Steam component, it restores reliable, automated blowdown function, helping facility operators maintain consistent boiler performance and extend the service life of heating elements in demanding commercial environments.
