Threaded Ball Valve - B3 series stainless steel two-piece - 3”; L=173mm BRA.B3.622

Product detailed description

Threaded ball valves are essential components in industrial and commercial heating, ventilation and plumbing systems. They are commonly used in applications where reliable shut-off and minimal pressure drop are required. This two-piece model is suitable for systems operating with water, oils and hydrocarbons. It is frequently found in building services, industrial plants and infrastructure projects where medium to high-pressure conditions are typical.

Installers and technicians working with this model will encounter systems that require durable and corrosion-resistant components. The valve is designed for environments with fluctuating temperatures and pressures, making it suitable for both heating and cooling applications. Its compact design and locking lever allow for secure operation in hard-to-reach locations.

Code	B3622300
Brand	IVAR

The valve is rated for a maximum operating pressure of 63 bar and a temperature range of -25°C to +180°C. These parameters are critical for system designers when selecting the appropriate valve for the application. The stainless steel body and PTFE sealing ensure compatibility with a wide range of media, including potable water, oils and hydrocarbons. The full flow design minimises pressure loss in the system.

Installation and connection

This two-piece ball valve is connected via threaded ends, with thread sizes ranging from 1/4 inch to 4 inch according to ISO 228-1. The installation process involves aligning the valve body with the pipeline and tightening the connections to ensure a secure fit. It is important to verify that the thread dimensions match the system requirements and that the valve is installed in a position that allows for easy access and operation. Common installation errors include incorrect thread engagement and failure to check for alignment before tightening. The valve should be installed in a straight section of the pipeline to prevent stress on the body.

Compatibility and accessories

The valve is compatible with systems using water, oils and hydrocarbons. It is not suitable for steam or flow regulation applications. When installing, ensure that the system pressure and temperature are within the specified limits. No additional accessories are required for standard installation. The valve is certified for potable water and meets ATEX standards for use in potentially explosive environments according to EU Directive 2014/34/EU.

Technical background for designers

The valve operates by rotating a ball with a bore to either allow or block the flow of media. The stainless steel body (A351 CF8M) provides high resistance to corrosion and mechanical stress, while the ball and stem are made of AISI 316 stainless steel for enhanced durability. The PTFE sealing material ensures low friction and long service life. The two-piece design allows for easier maintenance and inspection. The valve is designed for integration into systems with full flow requirements and where a locking lever is beneficial for secure operation. The service life is influenced by the operating conditions, including the frequency of operation and the media's chemical properties.

Service and operation

The valve requires minimal maintenance due to its robust design and high-quality materials. Routine checks should include verifying the tightness of the connections and ensuring that the lever operates smoothly. No specific service intervals are provided in the technical data. The valve should be operated with care to avoid excessive force that could damage the stem or seating. In case of leakage or operational issues, the valve should be inspected for wear or damage to the sealing components.
