Product Overview
The BZW-50K-24VDC is a 2" 24V DC normally open brass solenoid valve designed for high-flow control of water, air, fuel, and other compatible media in commercial and industrial fluid systems. This 2-way valve remains open when power is off and closes when 24V DC is applied. Its normally open configuration is useful for systems that need to maintain fluid flow during a power interruption or require flow to stop only when the valve is energized.
Constructed with a durable brass body, stainless steel internal components, and a Viton® diaphragm, this electric solenoid valve provides automatic fluid control across a range of compatible media. It features 2" female NPT ports, a 50 mm orifice, and a Cv of 48, delivering approximately 370 GPM of water flow at 60 psi.
The valve operates at 0 to 90 psi, with a media temperature range of 15°F to 250°F. Its 24V DC coil requires 30 W/1.25 Amps, uses a DIN 43650A electrical connection, responds in less than one second, and is rated for 100% duty at rated ambient temperature. No minimum operating pressure is required. Verify media compatibility, pressure, temperature, and flow requirements before installation.
Common Applications
Common applications include:
- Emergency cooling-water circulation
- Industrial water distribution
- Water treatment and filtration
- Bypass and recirculation lines
- Process draining
- Purging systems
- Irrigation
- Solar heating
- Hydroponics
- HVAC
- Plumbing
Installation
- Install the valve using compatible 2" female NPT pipe connections, following the directional arrow on the brass body.
- The valve can be mounted in different orientations, provided the flow direction is correct and the installation is properly supported.
- Connect the coil to a correctly rated 24V DC power supply capable of supplying 30 W/1.25 A. The DIN 43650A electrical connection must be properly secured.
- Flush the piping before installation, and we recommend an upstream filter to help prevent debris from interfering with the diaphragm.
- This valve is designed for unidirectional flow and does not prevent reverse flow.
*Consult a chemical compatibility expert for correct seal and valve body material choice.
