ASCO™ 212 Composite Valve
asco 212 series engineered composite
ASCO has perfected composite valve technology with the Series 212, also known as 8212, plastic solenoid valves.
The robust, easy-to-install valves are designed specifically for water purification and conditioning systems in commercial and industrial applications. With the highest pressure and temperature ratings on the market -- up to 150 psi and 150°F - the 212 Series solves the breakdown and reliability problems found in other types of composite valves. Its lightweight engineered plastic body has been built and tested to achieve up to 1 million operating cycles. The 212 Series comes with ASCO's new FasN universal connection system - the world's fastest, most secure valve connection technology.
