Product Overview

The BZW-32K-110VAC is considered a two-way, semi-direct valve or assisted lift solenoid valve. Semi-direct solenoid valves are a mix between a direct-acting and pilot-operated solenoid valve; they use both armature movement to allow for lower-pressure or gravity-feed applications, as well as an additional pressure chamber which creates a pressure differential to assist in moving the diaphragm for higher-pressure applications. Semi-Direct valves are the most common type of brass general purpose solenoid valves.

Semi-direct valves are uni-directional, as noted by the arrow molded onto the valve body, and if there is backflow in your application, check valves are recommended. This valve will not prevent flow in the opposite direction intended. This valve, the BZW-32K, is Normally Open, which refers to the non-energized position. This valve series is Normally Open, or in the Open position when not energized. Once energized, this valve will snap shut in under one second as the coil creates a magnetic field that pushes the diaphragm down against a spring! This valve will remain closed until the power is switched off and the spring pushes the diaphragm back up, allowing media to pass through the valve once again.

This brass electric solenoid valve comes standard with a Viton® rubber seal. Viton® rubber is compatible with a wide range of media, including hot water, air, gas, diesel fuel, Freon, weak acids, and weak alkali, and is popular for its ability to withstand wide temperature and pressure ranges. This valve boasts a temperature range of 15°F to 250°F and a pressure range of 0 to 90 PSI.

Applications

This large range makes this valve extremely versatile and is commonly used in HVAC, plumbing, solar heating, and irrigation applications. Please note that semi-direct solenoid valves require a minimum pressure of 10 PSI for gases to open and close properly, and the flow rate for gravity-fed applications varies based on head height. Always consider pressure and flow rate when selecting a valve.

Installation

The BZW-32K-110VAC is fitted with a 110 Volt AC coil with an IP 65 Enclosure rating, which is the equivalent of an H Class Insulation Rating or a NEMA 4 waterproof level. This coil can accept voltages +/-10% of 110V AC, which matches the voltage in most homes, meaning it can be easily wired without a transformer. The coil comes standard with a DIN connector, allowing installers to use their preferred wires.
