Product Overview

Featured here is Model BZW-15 of our brass valve line. This particular valve is a two-way, semi-direct lift valve with a normally closed operating position. This means that there are two ports in which media flows and the valve will open when energized to allow media to pass through. Removing the energy from the valve coil will close it and stop 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 1/2” inch female NPT threaded. This Electric Solenoid Valve can handle low viscosity fluids below 20 cst. The orifice size is 16mm and the Cv value is 4.8. It can withstand pressure up to 115 psi and temperatures as low as 15°F and as high as 250°F. The seal material is VITON Rubber. 

This specific valve has a 12 Volt DC coil with a voltage range that is -+ 10. The coil head is fitted with a 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-15 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. 

*Consult a chemical compatibility expert for correct seal and valve body material choice.

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

Installed on a boom sprayer, they worked well after installation. It appears they will be fine during the next spray season in a few months.
