Gv. with fitting, 1/2" FM, butterfly

Product detailed description

This butterfly ball valve with fitting is designed for use in water supply lines within residential and commercial buildings. It is commonly installed in heating systems, plumbing circuits, and irrigation setups where reliable shut-off is required. The valve allows for quick and secure isolation of water flow during maintenance or emergencies. The compact design and robust materials make it suitable for both indoor and outdoor installations, provided environmental conditions remain within specified limits.

The valve is typically used in conjunction with copper or steel piping systems and is compatible with standard threaded connections. Installers should ensure correct orientation and sealing to prevent leaks and maintain system integrity. Its PN 50 pressure rating makes it suitable for medium-pressure water systems, while the operating temperature range ensures functionality in both cold and warm environments.

Installation and connection

This valve is equipped with a 1/2 inch female metric (FM) thread for direct connection to threaded pipe ends. Before installation, ensure the pipe threads are clean and free from debris. Apply a suitable sealing compound or PTFE tape to the male thread to prevent leakage. Tighten the connection using a wrench, taking care not to overtighten and damage the threads or seating surface. Common installation mistakes include incorrect thread orientation and failure to verify the direction of flow. Always install the valve so that the flow enters the straight end of the body and exits through the opposite side. After installation, perform a visual inspection for misalignment and test for leaks under low pressure before commissioning the system.

Compatibility and accessories

This valve is compatible with standard water piping systems using copper, steel or plastic pipes with metric threading. For optimal performance, it should be used in conjunction with standard pipe fittings such as elbows, tees and couplings. Additional components such as pressure-reducing valves or filters may be required depending on the specific application and system requirements.

Technical background for designers

The valve operates via a rotating ball with a central bore that aligns or blocks the flow path. The ball is seated between two metal-to-metal seals to ensure a tight shut-off even under pressure. The nickel-plated brass body provides resistance to corrosion and wear, making it suitable for long-term use in potable water systems. The PN 50 rating indicates that it can handle sustained pressures up to 50 bar at room temperature, though this capacity decreases with increasing temperature. Designers should consider the minimum operating clearance required for the butterfly handle when planning the layout. The valve’s performance is influenced by the quality of the installation, particularly the alignment of the pipe and the integrity of the sealing surfaces. Regular inspection and maintenance will help preserve its efficiency and extend service life.

Service and operation

Routine checks should include verifying the tightness of the connection and ensuring smooth operation of the handle. Any resistance during turning may indicate sediment buildup or wear on the sealing surfaces. In such cases, the valve should be disassembled for cleaning or inspection. No specific service intervals are provided in the technical documentation, but periodic checks are recommended in high-use or harsh environments.

Frequently asked questions

Can this valve be used in potable water systems?
Yes, the valve is constructed from nickel-plated brass CW617N, which is certified for use with drinking water.

What is the maximum working pressure of this valve?
The valve has a nominal pressure rating of PN 50, meaning it is suitable for systems operating at up to 50 bar at standard temperatures.

Is it possible to install this valve in a horizontal or vertical position?
Yes, the valve can be installed in either horizontal or vertical positions, provided the flow direction is maintained as indicated on the body.

Can this valve be used in systems with temperatures below freezing?
Yes, the operating temperature range includes down to -20°C, allowing for use in cold environments without risk of material failure.
