Product Overview

Featured here is Model BZW-20K-110V of our brass valve line. This particular valve is a two-way, semi-direct lift valve with a normally open operating position. This means that there are two ports in which media flows and the valve will close when the coil is energized to stop media from passing through. Removing the energy from the valve coil will open it and continue the flow. It works across various media such as hot water, air, gas, diesel fuel, Freon, weak acids and weak alkali. The valve features a heavy duty, solid brass body that’s sure to last in the most strenuous projects.

The port size is 3/4” inch female NPT threaded. This Electric Solenoid Valve can handle low viscosity fluids below 20 cst. The orifice size is 20mm and the Cv value is 7.6. It can withstand pressure up to 90 psi (6 bar) and temperatures as low as 15°F and as high as 250°F. The seal material is VITON. 

This specific valve has a 110 Volt AC coil with a voltage range that is -+ 10. The coil head is fitted with a DIN connection and has 5’’ wire lead that can easily be connected with your own choice of terminals. The top of the coil features a label that indicates the valve type and specifications. Its response time is very low; in fact, it acts in less than one second, making it a great choice for all types of applications.

Customers commonly use the BZW-20K-110V Valve for Irrigation, Fountains, Water Filtration, Solar Heating, Aquariums, Automotive, Beer Brewing, Hydroponics, HVAC, and Plumbing and everywhere else one of our valves can be applied.

This model is mountable in any position and features a conveniently positioned arrow on the body to indication the direction of flow. 

Warranty guarantees our valves to be free from defects in workmanship and materials under normal use for One year from the date of purchase.

Main house water simple shut off

Posted by David Eggert on 21st Sep 2018

This is terrific! Used Pex fittings to install to my house incoming water in crawl space. Picked power up from electrical outlet and installed a switch. Now throwing switch closes valve which completely shuts water to house. So dont have to worry about a water leak when away!!!!!!! Everybody needs to do this!!!!!

appears to work well

Posted by david on 11th Oct 2017

similar item (but normally closed) provided by another company said not to energize more than 8 hours because it might overheat the solenoid. Does this also apply to your valves? using valve in fall/winter/early spring only at elevation 7,000 feet in northern california. Wrapped and buried valve in valve box for freeze protection. Do i need to keep the underside of the black round cover open for cooling or ok to cover with insulation????? thanks
