Product Overview

Featured here is Model NOB12-110V 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 1/2” inch female NPT threaded. This Electric Solenoid Valve can handle low viscosity fluids below 20 cst. The orifice size is 15mm and the Cv value is 4.8. 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 NOB12-110V 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.

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

I had bought this valve to replace an ASCO valve that I was having trouble with due to not closing when turned back on too fast after being turned off, this valve worked great! and for a fraction of the cost, I will be buying four more to replace others which need to be swapped as well.
