Poppet valve ZB-50K flanged poppet valve DN50, 12V coil

Mushroom valve for securing gas installations

This flanged mushroom valve ZB-50K is a key element of safety systems in gas installations, designed to quickly shut off the gas supply in the event of a hazard. It is ideal for gas boiler rooms, residential buildings and other facilities where safety is a priority. The valve is opened manually and closed by a 12V electrical impulse or manually – providing flexibility and reliable operation.

Construction and operating principle

The ZB-50K valve is characterized by a design that allows for quick and reliable shut-off of the gas supply. It operates in a gas detection system, responding to a signal from sensors detecting dangerous concentrations of natural gas or propane-butane. An electrical impulse (lasting less than 1 second) causes the valve to close, minimizing the risk of explosion. It is worth emphasizing that the valve does not require a constant power supply – it only draws power when closing. This is an energy-saving solution that will not fail in the event of a momentary power outage.

Key features and applications

• Quick gas shut-off: Immediate reaction to a signal from the gas detector ensures a high level of safety.
• Versatility: It can function as both a shut-off valve in a gas detection system and a manual shut-off valve.
• Energy saving: No need for a constant power supply – an electrical impulse is only needed to close the valve.
• Reliability: Resistant to interference and accidental opening in the closed state – only conscious action can reopen it.
• Simple operation: Requires little force to open and operate.
• Equipped with a mesh filter: Ensures long life and protects against contamination.
• Compliance with standards: Meets the requirements of PN-EN161 standard, guaranteeing safety of use.
• Wide range of applications: Ideal for low-pressure gas installations in boiler rooms, residential and industrial buildings.

This valve is used wherever effective protection against gas leakage and potential explosion hazard is required. Its solid construction and high quality workmanship guarantee long-lasting and trouble-free operation. Flanged mounting facilitates integration with the existing infrastructure of the gas installation with a diameter of DN50.
