Gv. indoor - outdoor, 3/4" MF, butterfly

Product detailed description

This indoor-outdoor ball valve is commonly used in heating, plumbing and irrigation systems for controlling the flow of water, air and other non-aggressive media. It is suitable for both indoor and outdoor installation, making it ideal for use in residential, commercial and industrial buildings. The valve is designed to ensure tight sealing and reliable operation under varying environmental conditions. It is particularly useful in applications where frequent switching is required, such as in distribution systems and control circuits. The compact design allows for easy integration into existing piping systems without requiring major modifications.

The valve is typically used in systems where a high degree of reliability and resistance to corrosion is required. Its construction ensures compatibility with standard pipe connections and facilitates straightforward installation. It is especially suited for environments where temperature fluctuations are common and where long-term durability is essential.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 40
Weight	0.216 kg
Code	8367R005
Brand	IVAR

The nickel-plated brass body provides resistance to corrosion and ensures compatibility with potable water systems. The PN 40 rating indicates the valve can handle pressures up to 40 bar at nominal temperatures, making it suitable for high-pressure applications. The operating temperature range from -20 °C to +120 °C allows for use in both cold and hot water systems. These parameters are essential for determining correct sizing and ensuring the valve meets the operational requirements of the system.Installation and connection The valve is connected using a 3/4 inch male-female (MF) thread, which requires precise alignment during installation to prevent leaks. The installation process involves preparing the pipe ends, applying a suitable sealing compound, and tightening the connections to the recommended torque. It is important to ensure that the valve is fully aligned with the pipe axis to avoid stress on the body. Common installation errors include cross-threading, improper sealing and incorrect orientation. After installation, the system should be tested for leaks and the valve operated through its full range to confirm smooth function.

Compatibility and accessories

This valve is compatible with standard copper, steel and plastic piping systems using MF threads. When installing, ensure that the entire piping system is designed to maintain coaxial alignment and that no external forces are applied to the valve body. No additional accessories are required for basic installation, though sealing compounds and wrenches may be needed for secure fitting. There are no related products listed for this model.

Technical background for designers

The valve operates via a specially shaped ball with surface depressions that reduce contact area between the ball and the sealing seat. This design minimises the accumulation of sediment and debris during operation, enhancing longevity and reducing maintenance requirements. The nickel-plated brass body offers good resistance to corrosion and mechanical wear, while the ATEST certification confirms suitability for potable water. The valve integrates into the system as a shut-off device, with its performance influenced by fluid velocity, media cleanliness and system pressure. Proper installation and alignment are critical to ensuring efficient operation and preventing premature failure.

Service and operation

The valve is designed for trouble-free operation and does not require regular maintenance. However, it is recommended to operate the valve fully once every six months to prevent the build-up of sediment on the ball surface. The body of the valve is permanently bonded and cannot be disassembled, meaning any damage beyond the handle or stem must result in full replacement. The valve must not be exposed to temperatures exceeding 185 °C, and welding operations should be performed at least 20 cm away from the valve body to avoid thermal damage.

Frequently asked questions

Can this valve be used in a domestic hot water system?
Yes, it is suitable for hot water systems with operating temperatures up to +120 °C.

Is this valve suitable for underground installation?
Yes, provided that the installation site is protected from direct mechanical impact and excessive moisture.

Can the valve be repaired if damaged?
No, the body of the valve is permanently bonded and cannot be disassembled or reassembled for repair.

What is the recommended method for sealing the threaded connections?
A suitable sealing compound or PTFE tape should be applied to the threads before tightening to ensure a leak-tight seal.
