Electromagnetic threaded valve for heating gases - 1/2"; PN 6; NC; brass IVAR.M16-RMO

Product detailed description

This electromagnetic threaded valve is commonly used in residential and commercial heating systems where gas is the primary heating medium. It is typically installed in gas supply lines to regulate and shut off the flow of gas in response to signals from gas detectors or in the event of a power failure. The valve ensures a secure, normally closed (NC) shut-off, making it a critical component in systems requiring safety and reliability in emergency conditions.

Its compact design and robust construction make it suitable for installation in boiler rooms, utility areas, and other controlled environments where gas lines are integrated with automated control systems. The valve is often part of a larger safety network that includes pressure regulators, gas detectors, and control panels. Installers must ensure that the valve is correctly sized and positioned to maintain system integrity and response times.

Technical parameters

Installation and connection

The valve is designed for 1/2 inch threaded connections and should be installed in accordance with standard piping practices for gas systems. Prior to installation, the system must be depressurised and the valve inspected for any damage or defects. The manual override feature allows for temporary opening without electrical power, which is useful during maintenance or testing. Common installation errors include incorrect thread orientation, failure to use appropriate sealing materials, and improper alignment with the control system.

Compatibility and accessories

This valve is compatible with gas supply lines and control systems that operate within the specified pressure and temperature ranges. It is typically used in conjunction with gas detectors and control panels that provide the necessary electrical signals for operation. Additional components such as pressure regulators and flow meters may be required depending on the system configuration. No specific related products are listed for this model.

Technical background for designers

The valve operates on an electromagnetic principle, where an energised coil opens the valve and de-energisation causes it to close. The NC configuration ensures that the valve remains closed in the absence of power, which is critical for safety in gas systems. The integration of this valve into a control system requires careful consideration of signal timing and system response to ensure rapid and reliable shut-off.

Service and operation

Regular inspection of the valve is recommended to ensure continued performance. This includes checking for signs of wear, verifying the integrity of the sealing surfaces, and testing the manual override function. No specific service intervals are provided in the technical data. During operation, the valve should be monitored for any unusual noise or vibration that may indicate internal issues. The IP65 rating provides protection against dust and water ingress, but the valve should not be submerged or exposed to extreme environmental conditions.

Frequently asked questions

Can the valve be used with gas detectors?
Yes, the valve is designed to respond to signals from gas detectors, ensuring a secure shut-off when gas concentration exceeds safe levels.

What happens during a power failure?
During a power failure, the valve remains in the closed position due to its normally closed (NC) configuration, ensuring system safety.

Is the valve suitable for low-temperature environments?
Yes, the valve is rated for operation at a minimum temperature of -20°C, making it suitable for use in cold environments.

Can the valve be manually opened?
Yes, the valve includes a manual override feature that allows temporary opening without the need for electrical power.
