Poppet valve ZB-32, thread 1 1/4", coil 12V

Mushroom valve for securing gas installations

The ZB-32 mushroom valve is a safety system component designed to quickly shut off the gas supply in the event of its detection. It is a key component in low-pressure gas installations, providing protection in boiler rooms, residential buildings and other facilities. Its operation is based on cooperation with gas detectors – after exceeding the permissible gas concentration, the valve immediately closes, minimizing the risk of explosion or poisoning.

This valve is distinguished by its versatility – it can also function as a manual shut-off valve, which increases its practicality. The valve's design is designed for reliability and energy efficiency. It does not require power in the open or closed position, and a short 12V electrical pulse or manual button press is sufficient to close it. This makes it resistant to voltage drops and interference, guaranteeing continuous protection.

Construction and application

The ZB-32 valve has a 1 1/4 inch thread and is opened only manually. Closing occurs via a 12V electrical pulse or manually using a dedicated button. It is equipped with a mesh filter that protects it from contaminants and extends its lifespan. The application of the valve is wide – it is ideal for systems protecting gas installations in residential buildings, boiler rooms and industrial facilities. It can also be used as a permanent blocking element for gas-fired appliances.

Its simple construction is noteworthy, which translates into ease of installation and operation. Small maneuvering space and the small force required to open the valve make it easy to use even in difficult conditions. In addition, the valve meets the requirements of the PN-EN161 standard, confirming its compliance with European safety standards. The maximum working pressure is 25 kPa (0.25 bar).

Key features and benefits

• Fast gas shut-off: immediate reaction to a signal from the gas detector minimizes the risk of failure.
• Energy saving: no need for continuous power in the open and closed position reduces operating costs.
• Reliability: resistance to voltage drops and interference ensures continuous protection of the installation.
• Versatility: the possibility of use as a manual shut-off valve increases the functionality of the device.
• Easy installation and operation: simple construction facilitates installation and use of the valve.
• Compliance with standards: meeting the requirements of PN-EN161 guarantees safe use.
• Equipped with a mesh filter: ensures long device life by protecting against contamination.
• Compact dimensions: 145 x 155 x 101 mm make it easy to install even in tight spaces.
