Poppet valve ZB-40, thread 1 1/2", coil 12V

Mushroom valve for gas detection systems

The ZB-40 mushroom valve is an element designed for quickly shutting off the gas supply in safety systems for gas installations, especially in conjunction with gas detectors. Its design ensures an immediate response in the event of a dangerous gas concentration being detected, minimizing the risk of failure and ensuring safe use. This valve works well in gas boiler rooms, residential buildings, and other low-pressure installations. It can also function as a manual shut-off valve.

Construction and operating principle

The ZB-40 valve is characterized by a simple and reliable construction. It is opened manually only, while closing occurs via a short 12V electrical impulse or manually using a dedicated button. A key feature is that the valve does not require constant power in the open or closed position – an energy-saving electrical impulse is used only to close it. This solution guarantees continuous operation even in the event of brief power outages. A built-in mesh filter protects against contaminants and extends the life of the device.

Key advantages and applications

• Safety: Immediate shut-off of gas supply in the event of a detected hazard.
• Energy saving: No need for constant power – 12V impulse only to close the valve.
• Reliability: Resistance to interference and voltage drops, ensuring stable operation.
• Versatility: Can be used as part of a gas detection system or a manual shut-off valve.
• Ease of use: Small maneuvering range and little force required to open the valve.
• Durability: Equipped with a mesh filter protecting against contaminants.
• Compliance with standards: Meets the requirements of PN-EN161 standard, confirming its safety and quality.

The ZB-40 valve with a DN40 diameter and a 1 1/2" thread is an ideal solution for installers looking for a reliable and safe element of gas installation safety systems and for end-users who value a high level of safety in their home or business. Its simple construction makes it easy to install and maintain, and energy saving translates into lower operating costs.
