Ball valve - corner, 3/4" M x 3/4" F

Product detailed description

This corner-mounted ball valve is specifically designed for integration into gas supply systems where fire safety is a critical requirement. It is commonly used in residential and commercial buildings for gas distribution lines, particularly in areas where fire risk is a concern. Installers working on gas piping systems will find this valve suitable for applications where a compact, directional change in pipe routing is required. The valve’s fire safety mechanism ensures that gas flow is automatically cut off in the event of a fire, preventing further gas leakage and potential hazards.

The valve is designed for use in systems operating within a temperature range of -20°C to +60°C. The fire shut-off feature activates when ambient temperatures reach approximately +100°C, triggering a mechanical closure of the gas supply. This makes it ideal for installations in kitchens, boiler rooms, or other gas-related infrastructure where fire safety compliance is essential.

The operating temperature range and pressure rating are key factors in determining the suitability of this valve for a specific installation. The PN 5 rating indicates that it is designed for low-pressure gas systems, while the temperature range ensures compatibility with both cold and moderately heated environments. The nickel-plated brass construction provides corrosion resistance and mechanical strength, making it suitable for long-term use in gas applications.

Installation and connection

This valve is designed for external male to internal female thread connections (MF), with a 3/4 inch thread on both ends. During installation, ensure that the threads are clean and free from debris to prevent leakage. Apply a suitable thread sealant or PTFE tape to the male thread before tightening. The valve should be installed in a position that allows easy access for operation and inspection. A common mistake is over-tightening the connections, which can damage the threads or the valve body. Always verify that the valve is fully open before commissioning the system to ensure unrestricted flow.

Compatibility and accessories

This ball valve is compatible with standard gas piping systems using 3/4 inch threaded connections. It is intended for use with gas media and should not be used with other fluids or vapours unless specified by the manufacturer. No additional accessories are required for standard installation. Ensure that the system pressure and temperature conditions align with the valve’s specifications before installation.

Technical background for designers

The valve operates as a directional control device with a built-in fire shut-off mechanism. The ball inside the valve body rotates to open or close the flow path. The fire safety device, known as FIREBAG®, is integrated into the valve body and activates when the ambient temperature reaches approximately +100°C. The material, nickel-plated brass CW617N, provides high mechanical strength and resistance to corrosion, making it suitable for gas applications. The valve is designed to integrate seamlessly into gas systems, with its compact corner design allowing for space-efficient installation. The service life and efficiency depend on correct installation, regular inspection, and adherence to operating conditions.

Service and operation

No specific maintenance is required for this valve under normal operating conditions. However, it is recommended to periodically inspect the valve for signs of wear, corrosion, or leakage. Ensure that the fire shut-off mechanism is not obstructed and that the valve operates smoothly. If the valve has been activated during a fire event, it must be replaced as it is a one-time-use safety device. No service intervals are specified in the technical data.

Frequently asked questions

Can this valve be used in gas systems with a pressure higher than PN 5?
No, the valve is rated for a maximum pressure of PN 5 and should not be used in systems exceeding this rating.

Is the fire shut-off mechanism reusable after activation?
No, the fire shut-off mechanism is a one-time-use device and must be replaced after it has been triggered during a fire event.

Can this valve be installed in a vertical orientation?
Yes, the valve can be installed in any orientation as long as the connections are properly sealed and the valve is accessible for operation.

What is the maximum operating temperature for this valve?
The valve is rated for operation up to +60°C under normal conditions. The fire shut-off mechanism activates at approximately +100°C.
