Poppet valve ZB-20, thread 3/4", coil 12V

Mushroom valve for securing gas installations

The ZB-20 mushroom valve is a component of the gas installation safety system, designed to quickly shut off the gas supply in the event of its presence being detected at a dangerous concentration. It is a key component in gas detection systems, ensuring safety in boiler rooms, residential buildings and other facilities using gaseous fuels. The device is characterized by reliability and ease of operation, and its design allows it to work with various types of gas detectors.

Functionality and application

The ZB-20 valve is opened manually, providing control over the gas flow under normal operating conditions. Closing occurs automatically under the influence of an electrical impulse (12V=) generated by the gas detection system or manually using a special button. It is important to note that the valve does not require power in the open or closed position – an energy-saving electrical impulse is only needed to close it. This solution makes the valve independent of possible power failures, which increases safety. It can also function as a manual shut-off valve.

The valve finds application:

• in systems protecting gas installations in gas boiler rooms and residential buildings;
• in low-pressure gas installations;
• as an additional element for manually shutting off the gas supply.

Characteristics and benefits

The ZB-20 mushroom valve is distinguished by a number of features that translate into its reliability and functionality:

• Energy saving: No need for continuous power in the open and closed position minimizes energy consumption.
• Power independence: Loss of voltage does not affect the valve status – ensures continuous protection against gas leakage.
• Interference resistance: The design prevents accidental opening of the valve after it has been closed, which guarantees a high level of safety.
• Ease of operation: Small maneuvering field and little force required to open the valve make it easy to use.
• Durability: Equipped with a mesh filter that protects against contamination and extends the life of the device.
• Compliance with standards: Meets the requirements of PN-EN161 standard, which confirms its safety and quality.
• Versatility: Possibility of mounting in any position facilitates installation in various conditions.
• Simple construction: Ensures ease of servicing and replacement of elements.

The ZB-20 valve is a solid and reliable solution for anyone who cares about the safety of the gas installation. Its versatility and ease of installation make it an ideal choice for both professional installers and end users.
