Solenoid valve 1 inch WZB2 with coil, NO - normally open 149B12409

Solenoid valve with a diameter of 1 inch, designed for precise control of liquid or gas flow. The brass body construction ensures durability and corrosion resistance, making it an ideal solution for both installers and end-users looking for a reliable component. The valve is normally open (NO), meaning that in the resting state (no voltage on the coil) it allows the medium to flow.

Construction and application

The WZB2 valve is a two-way element made of high-quality materials. The brass body guarantees durability, and the stainless steel used for the spindle and spring ensures resistance to the medium. The EPDM gasket provides a seal and compatibility with water and other neutral liquids. The valve is used in irrigation systems, heating installations, and industrial processes requiring automatic flow control. A minimum differential pressure of 16 bar ensures stable operation even in harsh conditions.

Key features and benefits

• Durable construction: The brass body and stainless steel components ensure long-lasting and trouble-free operation.
• Versatility: Can be used with water and other neutral liquids thanks to the EPDM gasket.
• High performance: A Kvs value of 11 guarantees adequate medium flow while maintaining low pressure drop.
• Safety: The IP65 protection class of the coil protects against dust and moisture, ensuring safe operation.
• Easy installation: Internal threads facilitate connection to the existing installation.
• Reliable operation: The normally open valve type (NO) ensures safety in the event of a power failure – the medium flow is maintained.
• Energy saving: A 9W coil provides efficient operation with minimal electricity consumption (AC power supply).

This valve is also characterized by high precision and fast response time, which is particularly important in applications requiring dynamic flow control. This allows installers to be confident in the reliability of the system, and end-users – comfort of use. Additionally, the valve has hygienic certificates ACS (France) and PZH (Poland), confirming its safety for health and the environment.
