20 SERIES

HUNG DIAPHRAGM VALVE
NORMALLY CLOSED

The 20 series is Jemko's new line of solenoid valves for aboveground storage tanks and offers a more economical solution to AST anti-siphon control. The valve is a normally closed, Viton seal, hung diaphragm, brass body design. Similar in design and application to our standard 14 series valve but with a few additional features.

The 20 series has less moving parts, is lighter in weight and has easier field repairs. The 20 series valve can also be mounted in any position or attitude although, installing the valve in a horizontal line with the coil upright will offer a longer operating life. The 20 series is compatible for use with a number of products such as petroleum products, air, gases, water and other low viscosity media. It is recommended that 100 micron filtration be installed ahead of the valve to increase life expectancy and reduce maintenance.
