UV Emergency Solenoid Valve Kits
Many Sterilight UV systems can be equipped with an emergency solenoid shut-off kit. A solenoid is an electromagnetic device that moves a plunger up and down when a current is passed through a coil that surrounds the plunger. The valve defaults to a specified fail-safe (turns off water supply), upon loss of power or a serious alarm condition such as decline in UV output or lamp failure. Therefore, the water flow will cease if there is a loss in power, a lamp failure, or a loss of UV output below a safe dosage level, thereby providing extra safety and security to your UV system.
Why is this important? In the event of a power failure or electrical outage to your home, your UV lamp in your UV system will lose power. This could leave your home unprotected if someone turns on a water faucet. Some bacteria and other waterborne pathogens can also swim past an un-powered UV lamp and reach the downstream portion of your water system and therefore not receive a dose of UV light once the power is restored. The same situation could occur in the event of a UV bulb failure or in the event of a reduction in UV lamp output (drop in UV intensity below safe dosage level). The solenoid emergency shut-off valve is normally installed at the output of your UV system and will physically close a valve in the event of a lamp burn-out, or power failure, thereby preventing any contaminant from passing through the system untreated. This feature will also turn off the water supply if there is a UV intensity decline below a safe treatment level in all for models equipped with a UV intensity monitor.
An emergency solenoid shut-off kit is highly recommended for all homes with a known bacterial, virus, or cyst contamination problem, and for all homes with an electrical supply that is prone to frequent outages.
Sterilight Emergency Solenoid Valve Shut-Off Kits
The Sterilight emergency solenoid shut-off kits are composed of 2 primary components; the actual solenoid valve and a wire harness/junction box package which allows you to easily make all of the necessary wiring connections. Our kits include both components. While an emergency solenoid shut-off kit can be added at a later date, for ease of installation we recommend that it be purchased and installed when you buy your UV system if at all possible.
All Sterilight solenoid valves kits include the wire harness and junction box (if required), designed for 110 volt (50-60 hz) operation.
All Sterilight valves are NSF/ANSI 372 validated for lead-free compliance, NSF/ANSI 42 and 61 for material safety requirements for drinking water treatment systems, and NSF/ANSI 169 for special purpose food equipment and devices.
Valves sizes ranging from 3/4" to 1" are available. Please note that a solenoid emergency shut-off cannot be used with Copper Series or basic Silver Series models as their controllers do not have the appropriate hardware.
